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 Pediculari 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.
Full Size ImagePartially weeded patch os smooth brome at the top of the hill.
Full Size ImagePost-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 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 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.
  • Artemisia dracunculus L. Tarragon, Dragon Wort
  • Artemisia frigida Willd. Prairie Sagewort
  • Artemisia ludoviciana Nutt. Silver Wormwood
  • Erigeron divergens Torr. & A. Gray. Spreading Fleabane

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)

Despite the small size of the town, this is a strategic location, lying in a broad mountain pass on the divide between the Yampa River to the north and the Colorado River to the south. As a result, the town is traversed by not only State Highway 131, but also the former Craig branch of the Denver and Rio Grande Western Railroad.

No. 2090, 26 June 2019, characters observed: Annual/Perennial unknown (planted Spring 2019), height 60-90 cm., clumped; Leaves, sheath and blade differentiated, soft; Sheath, 80 mm., closed, generally glabrous, except collar somewhat hairy; Ligule, membraneous, 2 mm.; Auricles, absent; Blade, 140 mm. × 7 mm. wide, flat, scabrous, mid-rib prominent; Inflorescence, 1 per culm, >leaves, panicle, 180-200 mm. × 40-90 mm. wide; Rachis, not extended, minutely scabrous on abaxial side; Spikelets, many (#22-26), 36 mm. × 11 mm. wide, similar, 1 per node; Compression, lateral; Disarticulation, between the florets; Glumes, lower, 9.5 mm., veins, #5, distinct, upper, 12 mm., <lowest floret, veins, #7, distinct keeled, membraneous, awns, 0, margins short ciliate; Florets, 6 per spikelet; Rachilla, exposed, scabrous on abaxial side, not extended; Lemma, 13 mm., broad, 2.5 mm. midvein to margin, >glumes,ovate, keeled distally, finely short hairy throughout, veins, #9, glabrous, margins, scarious, tip, entire, awns, #1, 8 mm., straight, attached near tip; Palea, 7 mm., <lemma, keel, ciliate, veins, green, margin, glabrous, tip, entire; Anthers, 3.6 mm., yellow; Ovary, hairy. Keys poorly in most Colorado floras, but quite nicely to B. carinatus var. carinatus in the Jepson Manual (Baldwin, et al., 2012), in good part by the length of the lemma awn. Regardless, I think this is very likely a commercial cultivar used in revegetation.

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.
