The published literature I used was primarily Post's (1956) dissertation on Swertia of the western United States, and Kartesz' (1988) flora of Nevada. The herbarium specimens I have examined were at UC/JEPS, CAS/DS, RSA/POM, and a few smaller local herbaria. Online collection was obtained from the Consortium of California Herbaria and the Southwest Environmental Information Network. These two virtual herbaria have been accessed many times over a period of years, often late at night while wearing my robe and bunny slippers. As of this writing, 25 Feb 2012, I am aware of 1178 vouchers of Frasera from the following herbaria: RM (216), NY (125), UTC (112), UC+JEPS (111), CAS+DS (101), RSA+POM (96), ASC (58), UCR (41), CS (31), ARIZ (23), GH (12), ASU (11) and others (103). I keep this data in a Microsoft Access data base and an ArcGIS feature class. Specimen records that include geographic coordinates, or enough information to estimate geographic coordinates, are plotted on the distribution maps. About 65% of collections have usable geographic coordinates, 22% do not have coordinates and have been located at the nearest named location, 9% are re-located by me because of obvious errors in the geographic coordinates, and the remainder of 4% are GPS locations of observations without a collection. In addition to the map and summaries that follow, the source data used to prepare the map and summaries is available at "Distribution of Frasera albomarginata." If you are interested in current distribution maps, I would recommend starting with fresh data from CoCH and SEINet, so that your maps will include recent collections. | ||||

Locations: Benson. Johnson. Little Dragoon Mountains. |
Southeastern Arizona
Two of the three collections appear to have been made close-by to each other, at locations described as "near Johnson," and "in the foothills of the Little Dragoon Mountains." Both of these locations are on the southeast side of the Little Dragoon Mountains. R. A. Darrow collected Frasera albomarginata (#3451, 3 May 1946, ARIZ) 3 miles north of Johnson, on alluvial soil from limestone ridge, with associated mesquite and Flourensia, a tarwort. Post (1956) saw this collection at a time when it was the only collection from this area. R. K. Van Devender and W. D. Peachey collected (#93-618, 5 May 1993, ARIZ) in the foothills of Little Dragoon Mountains, about 3.2 mi from pavement at Johnson Road exit of I-10, beyond Arimetco mine pit, where it was described as abundant along disturbed roadside in overgrazed grassland. I attempted to visit this locality on 1-Jun-2008, leaving Benson early on a Sunday morning, and heading east up I-10 for Dragoon Summit, and the former town of Johnson. I ran into locked gates at all three roads north from I-10. The Johnson Mine, which appeared to be in the middle of my route to the Little Dragoon Mountains, was locked up tight, and not a soul in sight. Maybe on a weekday I could have obtained permission to pass through, but not today. The mountains above the mine appeared to be Pinyons and Junipers on limestone, the right environment for Frasera albomarginata. | ||||

On 1-Jun-08, I searched the area 10 miles south-southeast of Hookers Hot Springs fairly carefully. This would be on 3 Links Road, in the pass between Tres Alamos Wash, and the San Pedro River. There is some limestone here. However, the vegetation is ocotillo, prickly pear, agave, and mesquite. It's just not quite high enough for Frasera albomarginata. I now think it likely that the described location of 7 miles southwest of Hookers Hot Springs is correct, and the geographic coordinates and PLSS description given by the collectors is wrong. That location would be along the spine of this same ridge, but at a higher elevation, and may be a more likely habitat for Frasera albomarginata. | ||||

Locations:
Johnson.

On 26 April 2011, with the permission of Nord Resources, Inc., I once again visited the Johnson site, traveling past the mine to a location near the northern boundary of the mine. I made two collections of F. albomarginata, and nine collections of associated species. All these collections were deposited at UC. John L. Anderson (#2012-15) made an additional collection north of the Johnson Camp Mine in June, 2012. | ||||

Locations: Petrified Forest National Park. |
Regardless of the proximity of the three collections, the group is separated by quite a distance from any other collections of Frasera albomarginata. The nearest other collections were made about 220 miles (335 km) north at Petrified Forest National Park. | ||||

Petrified Forest National Park
The third collection, by R. H. Peebles and E. Q. Smith (#13965, 15 Jun 1938, US, GH, NY, ARIZ) was made at the south entrance of the park. On 2-Jun-08, I drove through Petrified Forest National Park. Again I did the Figure 8 Snipe Hunt Routine every half mile, from the south entrance to about the mid-point of the park. No Snipe, or Frasera albomarginata, for that matter. Asked a Ranger, but learned that they have Law Enforcement Rangers here, not Interpretive Rangers or (heaven forbid!) a biologist on staff. Their volunteer "wildflower lady" had a nice poster in the Museum, but not with my little plant. This Collared lizard was the prettiest thing I found. He was clearly waiting for someone to take a photo. | ||||

The third collection (David R. Goddard, #608, 14 June 1927, UC) gives a location 8 miles south of Oak Creek Lodge, which would be in the Wilson Canyon or Casner Canyon area, about 2 miles north of Sedona. At this location, Frasera albomarginata was growing on exposed slopes and abundant.
On 31-May-08 I thought to stop at Casner Canyon and hike a bit. However, the miniscule lot was full of two tourist busses with tourists. So I went on to the next canyon south. Hiked around here for a half-hour or so, but saw no Frasera albomarginata. | ||||

The Colorado collections are primarily from Mesa Verde, where the taxon was collected by Alice Eastwood and Townsend Brandegee. Townsend Brandegee was at Mesa Verde in 1875 (#1249, MO, PH, MICH, UC). The collection(s) by Alice Eastwood may be one or more collections and are found at CAN, COLO, UC, and US. At least one collection was made 1 July 1889.
A brief discussion with the park biological staff revealed that the taxon was found on Weatherill Mesa, and on the lower mesas of the Ute Mountain Indian Reservation. | ||||

There is a collection from the Canyon Rims Recreation Area between the Colorado River and the Manti - La Sal National Forest. This collection by W. C. Hodgson with Ron Hill (#9235, 18 Jun 1995, NY188580) was made at the Sundance Trailhead into Dark Canyon Wilderness, end of Road 208A (37°50'49'N, 110°12'48"W), which I believe to be near Squaw and Papoose Rock, the nearest landmark with an accepted name in GNIS. Frasera albomarginata was found with Ephedra, Atriplex canescens, A. confertifolia, Cowania, Yucca angustissima, Gilia gunnisonii, Sclerocactus parviflora, Hymenoxys argentea, Pinus edulis, Juniperis, Bromus rubens, Calochortus, Coleogyne ramosissima, etc.
This area is accessed from Utah Highway 95 several miles southeast of its crossing of the Colorado River near Hite, Utah. My experience in travelling in this area is that most maps are accurate as to the placement of roads, but quite inaccurate with regard to the names of those roads. The Streets data set from the Utah State Geographic Information Database (SGID), however, appears quite accurate with regard to names and route numbers. | ||||

There is a collection by Rose E. Collom made 5-August-1939 (ARIZ 369229) at Rowes Well with no county name given. There is a Rowe Well, Rowes Tank, and Rowe Well Picnic Area all in the same vicinity about two miles south of the south rim of Grand Canyon and west of Arizona Highway 64. It seems reasonable to assume this is the location named "Rowes Well."
I attempted to visit this site on 30-May-08. From Arizona Highway 64, I drove west on what appears to be Forest Road 328 "Rowes Well Road" as far as the railroad and what looks like someone's private ranch. I wandered around here for the better part of an hour, but did not find Rowe Well, or Frasera albomarginata. In retrospect I was always south of Rowe Well. Next time, I'll take a map with me. | ||||

Also, there are two collections that were made south of the park entrance, at two different locations in 1946.
K. F. Parker, E. McClintock, and G. T. Robbins collected four miles south of south entrance to Grand Canyon National Park, finding Frasera albomarginata common in yellow pine openings (#6181, 14 August 1946, UC737082 , ARIZ). A little further south, ten miles south of South entrance to Grand Canyon National Park, K. F. Parker also found the species to be common along roadside in yellow pine forest (#6023, 15 Jul 1946, ARIZ). | |||||

The collection was made on top of the plateau, accessed by an oil exploration road. The undulating top of the plateau was clothed with a low, scattered forest of pinyon and juniper. The notation "CC" on the voucher indicates that the collection was made as part of a study of the central coal region of Utah (S. L. Welsh, pers. comm.). The notation of "Summerville" indicates the collection was made on the Summerville geologic formation. | ||||

The described location of Page Flat I assumed to be Paige Flat. The rest stop nearest to Paige Flat on US I-70 is the Ghost Rock Rest Stop.

Hualapai Mountain Road also crosses a basaltic flow. I did not see either Frasera albomarginata or any likely-looking habitat. A checklist of species (Anonymous, n.d.) found in Hualapai Mountain Park lists "Elkweed/Green Gentian" as being found in the park. Review of Hualapai Mountain geology does not show any limestone or other carbonate outcrops on the mountain, at least at the 1:1,000,000 scale (Hirschberg and Pitts, 2000) . | ||||

Finally, Post (1956) reports a collection of Frasera albomarginata by Marcus E. Jones (19-June-1890, POM) from "Bucksin Mountain, near Parker." Bucksin Mountain is listed as a synonym for Buckskin Mountain that is northwest of Parker. However, the elevation of Buckskin Mountain, and the vegetation that I can see in aerial and satellite photographs does not appear conducive to the presence of F. albomarginata. There are, however, two other locations in Arizona known as Buckskin Mountain. I think it's possible that Jones collected this specimen at one of the other Buckskin Mountains in Arizona.
Supporting this idea, Lenz (1986, p. 82) contains a long quote from Jones' biographical notes that places Jones on the road from Flagstaff, Arizona to Panguitch, Utah, in June 1890, crossing the Buckskin Mountains of Coconino County, Arizona and Kane County, Utah. I think it far more likely that Jones made his collection of Frasera albomarginata in the Buckskin Mountains of Cononino County, rather than that Buckskin Mountains of La Paz County, Arizona. Therfore, my map of the distribution of Frasera albomarginata shows this collection in the Buckskin Mountains of Coconino County, Arizona. | ||||

I found one Frasera albomarginata on Quail Hill. It happened to be growing in the tire tread of a long disused road. The seed is small and round and, maybe, it rolls to low places.

There does not seem to be a Burnt Creek in either the Quinn Canyon Range or the Grant Range. However, there is a Burnt Canyon, and a Burnt Canyon Spring, just north of Humboldt-Toiyabe National Forest Road 410, on the west side of the ranges. Humboldt-Toiyabe National Forest Road 410 forms the boundary between the Quinn Canyon Range and the Grant Range.

The collection in the Pahranagat Range was made by Searls and is deposited at F and GH as noted by
Post (1956). Beyond that, I have no other information specific to this collection. "Searls" is probably Fanny Searls (1851-1939). She graduated Laureate of Science in 1870 from Northwest Female College and studied for a year at Northwestern University, the first year women were admitted. In 1871 she travelled with her father, a lawyer, to the Pahranagat mines in Nevada. While there she collected 215 plant specimens, as well as minerals and fossils, which she gave to Professor Oliver Marcy at Northwestern University. In 1877 she received her M.D. from University of Michigan but couldn't get an internship. So she worked as a student nurse in New york until 1881 when she married a Chicago ophthalmologist: Henry Gradle. After her husband's death in 1911, she moved to Santa Barbara, California, where she lived until her death. Dalea searlsiae (A. Gray) Barneby is named for her. | ||||

Thorne (#13589, 6/24/1976) collected Frasera albomarginata on what they described as a gray ignimbrite outcrop. However, the rock unit comprising Crystal Peak, the Tunnel Spring Tuff, is a crudely stratified, non-welded rhyolite ash-flow tuff with clasts of Palaeozoic dolomite, limestone and quartzite making up 10 per cent of the tuff (McBride and Picard, 2000). It's not unusual to find Frasera albomarginata on volcanic or plutonic rocks, when they contain a substantial portion of carbonates like the Tunnel Spring Tuff.
Tunnel Spring, by the way is on the west side of the Tunnel Spring Mountains, about 10 miles west southwest of Crystal Peak. | ||||

Vouchers are at POM and NY.The New York Botanical Garden online records (http://nybg.org) report three collections by Marcus E. Jones from Nevada with names including "Currant." On 31 July 1923, Jones collected Eriogonum microthecum Nutt. var. lapidicola Reveal at the Currant Creek Mountains (NY282222). On the same day, he also collected Ivesia sabulosa (M. E. Jones) D. D. Keck at Currant Creek (NY834049). There are no other collections in this location until 8 October 1924 when Jones collected Frasera albomarginata S. Watson at the Currant Creek Mountains (NY188578). Currant Creek drains the Snake Mountains to the east. It's possible that Jones thought the name for those mountains was "Currant Creek Mountains." I also noticed that Jones' collections occasionally mix county names. For example, Palisade is sometimes listed in Elko County and sometimes in Eureka County. The same for Ruby Hill, although, place names containing "ruby" are fairly common throughout Nevada. The collection of Frasera albomarginata in the Currant Creek Mountains is such as odd collection, it must remain suspect until more evidence can be obtained of Jones' collection localities in October of 1924. | ||||

| I am a little surprised that I have not found a collection of Frasera albomarginata by Mary Beal, or by Willis Linn Jepson, who visited Mary Beal at the Providence Mountains. JEPS has 567 collections made by Mary Beal at the Providence Mountains, and 188 collections made by Willis Linn Jepson there, but none of them are Frasera albomarginata. | |||||
