Inflorescence of Coll. No. 2036, Besseya plantaginea

Described by James (1825) in his Catalogue of Plants, collected between Palmer Lake and Fountain.

… V[eronica] plantaginea. N. S.? Flowers spiked, unibracteate. Capsule nearly orbicular, dehiscent at the margin. Radical leaves numerous and large, oval-lanceolate, stiped. Margin crenate. Those of the scape few, sessile, and alternate, Spike long, dense-flowered.

This plant, so unlike in habit and appearance to the American Species of Veronica, seems referable to no other Genus among the Pediculariæ of Jussieu, to which it is manifestly nearly allied. Habitat on open plains within the Rocky Mountains; flowering in June and July.

Hufford and McMahon (2004) make a strong argument for submerging Besseya back into Synthyris.

A central concern is the paraphyly of Synthyris in the face of continued recognition of Besseya as a coordinate group. We advocate a classification that reflects our knowledge of evolutionary relationships, especially monophyletic groups. Thus, we consider it important that Besseya be classified as part of Synthyris (Hufford and McMahon, 2004).

The coordinates reported by my GPS receiver were (39.902637117,-105.275957342), but when mapped in ArcMap they were up on the side of the hogback. I'm sure the collection was made below the hogback fairly close to the stream. I used GoogleEarth to estimate different coordinates of (39.902078,-105.276874) which are about 125 m. to the southwest.

North Washington Open Space, Cressman Gulch, and Dakota Ridge.

Locations: North Washington Open Space.
Partially weeded patch os smooth brome at the top of the hill.
Post-weeding photo, not terribly enlightening.

Weeded a patch of smooth brome on top of the hill.

There was an isolated patch of smooth brome mixed into the remnant mixed-grass prairie on top of the hill. I estimate it to be 1 to 1.5 square meters in size.

Over the course of two days, with about 1 ½ hours of work, I pulled all of it. This resulted in 2 shopping bags of grass to dispose of. Probably weighed about 5 pounds. This material was removed to my residence and disposed of in the yard waste bin.

Generally, the culms snapped off at the ground surface. Though, in about ¼ to 1/3 of the stems I removed at least some root material. Occasionally I would get a rhizome to 6-8 cm in length.

I pulled mostly smooth brome, although occasionally I would also pull cheatgrass and alyssum.

I occasionally accidently pulled a native, such as mistaking a stem of scurf pea for a culm of smooth brome. However, overall, I suspect I did more damage to natives with my knees and shoes that by accidently pulling them.

Access to the patch without damaging the native vegetation was difficult. The plants are sometimes hidden in the litter, and sometimes too dense to step anywhere without stepping on a native. I noticed this with the cacti and with Eriogonum effusum.

The remaining native plant vegetation is shown in the list below.

Within the patch of smooth brome there were many small Echinocereus viridiflorus. It is not clear to me whether the small cacti were new seedlings and the smooth brome was acting like a nurse plant, or whether the cacti were small because of competition with the smooth brome.

Will removal of smooth brome simply prepare more habitat for cheatgrass and alyssum?

How quickly will the smooth brome re-assert its dominance in the patch?

How many years of weeding are necessary to completely remove the smooth brome?

Without post-weeding water, will the remaining natives suffer from root disturbance and from sudden exposure?

Should cheatgrass and alyssum be removed at the same time?

When weeding smooth brome around natives, should we be pulling the culms, or digging out the crowns and rhizomes?

Cacti exposed by weeding the smooth brome.

After weeding, I observed the following native plants in the weeded plot.

Looked for Colutea arborescens along Cressman Gulch.

C. arborescens is native to Europe and North Africa, but it is known on other continents where it is grown as an ornamental and used in landscaping for erosion control. It is also known in the wild as an occasionally weedy escapee from cultivation.

C. arborescens is on the monitor list of noxious weeds for Washington state, but has no special status in Colorado. Friends of Bidwell Park (Chico, California) lists it under the heading of "Plants ranked #1 on park priority list: Highly invasive. Should have immediate management," with the following comments,

Came from 1 plant in 1890s. Control attempted in past, focused eradication program started by FOBP in May, 2003 with about 1M plants removed so far. People spread seeds by "popping" pods as they walk through the park.

C. arborescens has potential to become invasive in New England (Martine, et al., 2008)

The construction of the condominiums at 410-416 North Ford Street bled over into the North Washington Open Space. The soil was disturbed, construction debris was dumped, and construction equipment was stored on the city-owned parcel. At completion of construction the construction debris and equipment was removed. The disturbed area was covered with a jute mat, and the area seeded. Unfortunately, the primary species seeded was Bromus carinatus Hook. & Arn. “California brome.” Colorado flora authors disagree whether California brome is native to the state (Shaw, 2008, and Ackerfield, 2015) or whether it is an alien grass (Weber & Wittmann, 2012). Regardless, there are no historic or recent collections of this grass made in Golden s.l. (SEINet, 2019). The closest old collection is an early 20th century collection from Mount Morrison (Bethel & Clokey #3998, 3 Jun 1921: CM234168, IND27631, RM88139 & UTC22795). There were no collections of B. carinatus when the Magic Mountain area was extensively collected E. H. Brunquist in 1959-1960, nor were there any collections from South Table Mountain when that mesa was collected by Loraine Yeatts in 1983-1984.

Therefore, I think it is fair to say that the planting of the grass as construction remediation represents introduction of an alien grass to Golden s.l. if not to Colorado. In addition, the seed was contaminated by Triticum aestivum L. “Wheat” as several specimens of that taxon were collected with the California brome. None of this was necessary, as there are numerous native grasses already growing in the North Washington Open Space that are easy to obtain and grow from seed.

Coll. No. 2110, 1 July 2019, characters observed: Perennial herb, decumbent to ascending, to 45 cm.; Stem, sparsely hairy; Leaves, apparently ternately compound with free foliaceous stipules, but described as “... leaves pinnately compound with 5 leaflets sessile on the stem such that the lowest pair of leaflets resemble foliaceous stipules ... Ackerfield (2015)”, leaflet, 11-12 mm. × (2.5)3.2-3.6(5) mm. wide; Inflorescence, umbel; Flowers, #(2)4-6, yellow; Stamens, united.

Width of leaves and flowers per umbel within range of both L. corniculatus and L. tenuis. Determined as L. tenuis because the range of characters occasionally equals the lower limit of the smaller L. tenuis, but never the upper limit of the larger L. corniculatus.

Lotus corniculatus, birdsfoot trefoil, is a Eurasian perennial legume, popular in temperate climates for pasture or hay and silage production. Its ancestry is controversial. While innumerable studies of L. corniculatus and allied species have been published, comprehensive morphological, geographical, and genetic studies are still needed. Nevertheless, there is sufficient information for a provisional analysis of the origin and relationships of this important economical species. Although sometimes defined to have diploid populations, L. corniculatus essentially appears to be tetraploid. Biochemical and genetic evidence indicates that this species is an allotetraploid. Although about a dozen diploid species have been proposed as ancestral to L. corniculatus, the evidence points strongly to four of these species. Lotus uliginosus uniquely shares a rhizomatous habit, an acyanogenic factor, and a tannin characteristic with L. corniculatus, clearly showing an especially close relationship, and reflecting the possibility that it is one of two direct parental species. Principal candidates for a second parent include Lotus alpinus, Lotus japonicus, and Lotus tenuis. ... An evolutionary sequence is suggested in which L. uliginosus hybridized with L. tenuis followed by introgression from L. alpinus and L. japonicus (Grant and Small, 1996).

Coll. No. 2154, 13 Jul 2019, characters observed; Annual, 12-20 cm.; Stems, erect, branched at and above the base; Leaves, alternate, sessile, oblanceolate, 14 mm. × 5.5 mm. wide, strigose, few hooked hairs on abaxial mid-rib; Inflorescence, scorpioid, greatly exceeding leaves, although there are flowers throughout the plant; Pedicel, in fruit << calyx; Calyx, in flower, 2.5 mm., fused ±½, lobes ±equal, strigose, some hairs hooked, in fruit 4 mm.; Corolla, white, lobes, blue; Nutlets, 1.2 mm., >>style, brown, smooth, shiny, margin sharp raised.

I applied M. micrantha because the inflorescence greatly exceeds the leaves and the plant is floriferous nearly to the base. Also hairs are hooked on the abaxial mid-rib of the leaves, a character only described for M. micrantha (see the Jepson Manual of California, 2nd ed.). This will key to M. arvensis in Ackerfield (2015). However, M. micrantha is not a possibility there. Distribution of collections of the two taxa (SEINet, 8 Dec 2019) show collections of M. micrantha in northeast Utah and southeast Wyoming, whereas collections of M. arvensis are much farther from Colorado.

Myosotis arvensis. Biennial or sometimes annual, 1-4 dm, often branched above, strigose to hirsute-puberulent throughout; lvs 1-6 cm ?3-16 mm, the lower mostly oblanceolate, the upper often more oblong or lanceolate; infl slightly if at all longer than the leafy part of the plant; mature pedicels ascending or spreading, equaling or generally surpassing the 3-5 mm cal; cal hirsute-puberulent and shortly uncinate-hispid; cor blue or occasionally white, the limb 2-4 mm wide; nutlets distinctly surpassing the style; 2n=50-54. Native of Eurasia, established in fields and roadsides from Nf. to Minn., s. sometimes to N.H. and W.Va. Summer. (Gleason, Henry A. & Cronquist, Arthur J. 1991. Manual of vascular plants of northeastern United States and adjacent Canada. lxxv + 910 pp.)

Myosotis micrantha. Annual or winter-annual to 2 dm, often branched from the base, ±hirsute-puberulent throughout; lvs seldom over 2 cm ?7 mm; plants floriferous nearly to the base, the lower fls scattered among the lvs; fruiting pedicels ascending or somewhat spreading, under 2 mm, shorter than the 3-5 mm cal; cal strigose at least above, the tube also shortly uncinate- hispid; cor blue, the limb 1-2 mm wide, not flat; nutlets surpassing the style; 2n=36-40. Native of Eurasia, locally intr. in dry waste places; Que. to Va., Mich., and Io. Apr.-July. (M. stricta) (Gleason, Henry A. & Cronquist, Arthur J. 1991.

Coll. No. 2205, 27 August 2019, characters observed: Perennial herb, to 35 cm., short-hairy throughout; Stem, ascending from a creeping rootstock; Leaves, mostly cauline, alternate, petiole, 25 mm., blade 40 mm. × 9 mm. wide, reduced distally, oblanceolate, margin, entire, tip, round, veins (nerves), #1, eglandular, short hairy; Inflorescence, head enclosed by involucre, many heads per stem, not showy, 70 mm. × 26 mm. wide, elongated, not overtopped by leaves; Peduncles, 3 mm.; Involucre, 5 mm. × 2.5 mm. wide, cylindric-conic; Phyllaries, in 5± series, lower << rest of involucre, unequal, 4 mm. × 1.2 mm. wide, chartaceous with green tips, veins, #1, eglandular, margins, flat, tip, ciliate; Receptacle, epaleate; Flowers, 2 kinds; Ray flowers, #4, tube 2.5 mm. + blade 2 mm. × 0.7 mm. wide = 4.5 mm.; yellow; Disk flowers, #8, tube 3.5 mm. + lobes 0.5 mm. = 4.0 mm., yellow; Pappus, many well-developed bristles, 3 mm., ±equal; Fruit (cypsela), 1 mm. × 0.4 mm. wide, brown, hairy.

Keys to S. nemoralis in Weber & Wittmann (2012) and FNANM per the form of the inflorescence, yet the description in FNANM better describes this as S. nana especially in the number of phyllary series, and relative number of ray and disk flowers. Based on the key in Ackerfield (2015), would key to S. nana based upon the relative number of ray and disk flowers in the heads. Based upon the description in Ackerfield (2015), very similar to S. nana but S. nemoralis is a better fit because the ray flowers, disk flowers, and the cypselae are shorter.

In 1828 Schiede emigrated to Mexico, accompanied by Ferdinand Deppe (1794-1861), a German naturalist with previous experience in the country. The two scientists planned to collect zoological and botanical specimens, which would then be sold to museums and dealers in Europe. In July 1828 they settled in Jalapa, and performed scientific excursions throughout the state of Veracruz. Although they were able sell their collections to museums in Berlin and Vienna, the money earned was insufficient to continue operations, causing Deppe and Schiede to abandon their enterprise in late 1830. Christian Schiede died in Mexico in 1836 at the age of 38 (Wikipedia).

But ... Why is Lessing listed at the species author, and not Schlecht. & Chamisso?

Summary of Plant Collections – 2019

This is a combined summary of my 2019 plant collections for each agency that granted a scientific collections permit.

Locations: Lippincott Ranch.

City of Boulder Open Space and Mountain Parks

The Lippincott parcel in northernmost Jefferson County is jointly owned by City of Boulder Open Space and Mountain Parks, and Jefferson County Open Space. It was acquired in 2018 and is not yet open to the public.

Collections made in the Lippincott parcel were distributed to both agencies and to Denver Botanic Garden (KHD). In addition, Boulder OSMP issued a permit to cross the adjacent Lindsay/Jeffco parcel and to collect there.

There were 116 collections made in the Lippincott parcel that resulted in 95 vouchers distributed to the City of Boulder Herbarium (CIBO). I made three collections in the Lindsay/Jeffco parcel, all of which were in sight of the Lippincott fence.

City of Golden

On City of Golden parcels, I collected plants at Apex Gulch, Dakota Ridge, Deadman Gulch, Heritage Dells, North Table Mountain, and North Washington Open Space. I made forty collections that yielded 129 vouchers, the largest number being send to Denver Botanic Garden (KHD, 28 vouchers), Cal Poly State University (OBI, 18 vouchers), and Regis University (18 vouchers).

I made one interesting collection on Dakota Ridge, of Nuttallanthus texanus (Scheele) D. A. Sutton. [Syn: Linaria canadensis (L.) Dum.-Cours. var. texana (Scheele) Pennell] with common names of “Blue Toadflax” and “Texas Toadflax.” There is only one other collection from Golden. It was made more than 100 years ago by Francis W. Pennell, August 11, 1915, along the railroad tracks just west of Golden. In 2003 Loraine Yeatts collected the plant at White Ranch Open Space Park.

In connection with the Peabody Museum excavation of the Magic Mountain Archeological site in 1959-1960, E. H. Brunquist (1966) and others from the Denver Museum of Natural History surveyed the nearby area for plants. Their list numbers 185 species. This systematic collection serves as a benchmark. Re-collecting the area would provide some data about movement of plants into the area, or extirpation of plants. There are some taxonomic issues that require analysis beyond the scope of this report to resolve. Regardless, five taxa were found in 2019 that were not collected in 1959-1960. They are:

Centaurea diffusa Lam. White Knapweed. A Colorado Noxious Weed on List B.
Berteroa incana (L.) DC. Hoary Alyssum. A native of Eurasia.
Nasturtium officinale R. Br. Watercress. May or not be native, Colorado authors differ in their assessment.
Ligustrum vulgare L. Privet. An escapee from cultivation, native of Europe.
Potentilla recta L. Sulphur Cinquefoil. A Colorado Noxious Weed on List B, and common along the Front Range. Native of Eurasia.

There are not enough modern collections from the area to begin a list of possible extirpations.

Fourteen collections were made at North Washington Open space, adding ten taxa to the list of plants found there. The total number of taxa is now 126, of which 79 are native to Colorado, 44 are alien, and 3 are undetermined as to nativity. Revision of my document “Botanical Resources of the North Washington Open Space, Golden, Colorado” for 2019 collections is the next item on my list after this document.

The construction of the condominiums at 410-416 North Ford Street bled over into the North Washington Open Space. The soil was disturbed, construction debris was dumped, and construction equipment was stored on the city-owned parcel. At completion of construction the construction debris and equipment were removed. The disturbed area was covered with a jute mat, and the area seeded. Based upon actual collections, the primary species seeded was Bromus carinatus Hook. & Arn. “California brome.” Colorado flora authors disagree whether California brome is native to the state (Shaw, 2008, and Ackerfield, 2015) or whether it is an alien grass (Weber & Wittmann, 2012). Regardless, there are no historic or recent collections of this grass made in Golden (SEINet, 2019). The closest old collection is an early 20th century collection from Mount Morrison (Bethel & Clokey #3998, 3 Jun 1921). There were no collections of B. carinatus when the Magic Mountain area was extensively collected E. H. Brunquist in 1959-1960 (Brunquist, 1966), nor were there any collections from South Table Mountain when that mesa was collected by Loraine Yeatts in 1983-1984 (SEINet, 2019).

Therefore, I think it is fair to say that the planting of the grass as construction remediation represents introduction of an alien grass to Golden, if not to Colorado. In addition, the seed was contaminated by Triticum aestivum L. “Wheat” as several specimens of that taxon were collected with the California brome. None of this was necessary, as there are numerous native grasses already growing in the North Washington Open Space that are easy to obtain and grow from seed.

Locations: Colorado School of Mines Survey Field.

Colorado School of Mines

I crossed the Survey Field numerous times on my way to or from City of Golden or Jefferson County Open space properties. As it turns out I made several collections in the southeast corner that plotting of GPS data showed to be on the adjacent City of Golden parcel. So, officially, I can only count five collections in the Survey Field, from which 17 specimens were prepared. They were distributed to California Department of Agriculture, Denver Botanic Garden, California Academy of Sciences, and University of Colorado – Boulder.

Locations: Lippincott Ranch. North Table Mountain Park. Ranson/Edwards Homestead Open Space Park. Tin Cup Ridge.

Jefferson County Open Space

One hundred and seventy-five collections were made at four different properties: Lippincott parcel, North Table Mountain Park, Ranson/Edwards Homestead Open Space, and Tin Cup Ridge. These collections yielded 601 specimens that were distributed to Jefferson County Open Space (140 mounted vouchers), Denver Botanic Garden (KHD, 129 specimens), City of Boulder (CIBO, 96 specimens), etc.

At Lippincott one interesting collection was my #2150 of Hieracium albiflorum Hook. “White-Flower Hawkweed.” This taxon is known from Boulder County, but this appears to be the first collection from Jefferson County (SEINet, 2019). The collection was made in the southwest corner of the parcel in deep ponderosa pine woodland duff with a very sparse understory. Vouchers were distributed to JCOS, KHD and CIBO.

I also collected a small non-native forget-me-not, Myosotis sp., applying M. micrantha Pall. ex Lehm.because the inflorescence greatly exceeds the leaves and the plant is floriferous nearly to the base. Also, the hairs are hooked on the abaxial mid-rib of the leaves, a character only described for M. micrantha (Baldwin, et al., 2012). There are no other known collections from Colorado (SEINet, 1 March 2020). The voucher is at Denver Botanic Garden (KHD).

Locations: Little Scraggy Peak. Trout Creek Pass.

Pike – San Isabel National Forest

In 2019, I collected twice in the Buffalo Creek Recreation Area on the northeast slopes of Little Scraggy Peak. Nearby areas were extensively collected by Timothy W. Chumley in 1995 and 1996, with a total of 336 collections, all of which are at RM. I also made one short stop near Trout Creek Pass, for as long as my family could stand it. Neither of these are the most exciting places to collect. However, the 39 collections yielded 129 vouchers that were sent to Denver Botanic Garden (KHD, 32 specimens), California State Polytechnic University (OBI, 23 specimens) , University of California Riverside (UCR, 19 specimens), California Academy of Sciences (CAS, 13 specimens), etc. These will all be new specimens to those herbaria from this part of Jefferson County and valuable additions to their collections.

Plans for 2020

I generally plan to continue collecting in the same areas. For the City of Golden, the North Washington Open Space is well-collected, so my activities there will primarily consist of checking for things I might have missed. More trips should be directed toward other parcels, such as Kinney Run and perhaps Dakota Ridge in the north.

For Colorado School of Mines Survey Field, my list of collections is at 94 taxa. I estimate it should be around 200 taxa based on the landscape and the sizes of the two primary parcels, so there is some more work to be done there.

For Jefferson County Open Space, the Lippincott parcel still needs some work. This work would be combined with City of Boulder Open Space and Moutain Parks. At Ranson/Edwards there is one species of milkweed that has been seen and needs to be vouchered. It may be time branch out to some other areas as well.

In the Pike – San Isabel National Forest, I plan to continue working over the Little Scraggy Peak area, expanding a little into surrounding areas. I would also like to return to the Leadville – Tennessee Pass area, especially the West Tennessee Creek basin. I think there are still some interesting things to find there.
