Edward L. Greene (1898, p. 295) published Erigeron eximius in his Pittonia journal, citing a location of Marshall Pass, but no collector or collection. At the time of publication, Greene was at the Catholic University of America in Washington, D.C.

5. Some Western Species of Erigeron
E. eximius. Stems mostly several from a small branching crown or caudex, slender but rather rigid, 10 to 16 inches high, with few and scattered leaves ; herbage glabrous and glaucescent, except that the leaf-margins are sparsely hirsute-ciliate and the upper part of the stem and the peduncles rather densely granular-glandular, and with a few short spreading hairs: all the leaves perfectly entire, the tufted basal ones with spatulate-oblong obtuse blade and slender petiole ; the cauline from oblanceolate to spatulate and lanceolate, the middle and uppermost sessile : heads 4 to 9 (rarely 1 or 2), on slender rigid naked peduncles; bracts of the large involucre few and broad (only about 20), lanceolate, viscid-granular throughout, and only the very base hirsute : rays numerous and narrow, \ inch long or more, lilac-purple to rose-purple, rarely white.
Species abundant in pine woods below Marshall Pass, Colorado, and particularly on the lower slopes of Little Ouray Mountain in the same region, in rather dry ground; the allied, yet very different, E. Coulteri being as common in more moist and shady situations in the same district.

I have found no records in SEINet identifying a type for E. eximius.

There are several collections of Erigeron near Marshall Pass, but only one is likely E. eximius. It is Charles S. Crandall #2850 (NY2096920, CS110740). Initially determined E. superbus, CS110740 was annotated “ =E. eximius HDH 1949” The label states “Plants of Colorado, from Herb. State Agric. College, Colo.,” now Colorado State University, Fort Collins. The label also states “Distributed by The New York Botanical Garden.” HUH Botanist credits Crandall with 41 collections in 1896, some of which are lichens. SEINet (2022) lists 832 collections, concentrated mostly around Fort Collins, but including eight collections at or near Marshall Pass on 23 August 2022.

Whether or how E. L. Greene saw Crandall's collection is unknown.

Rydberg (1901, p. 24) published E. viscidus. The image of the type (NY168579) shows a plant that looks quite different from E. eximius.

Erigeron viscidus sp. nov.
A low cespitose perennial. Stems ascending, a little over 1 dm. high, more or less hirsute and glandular-puberulent, especially above ; leaves 3-5 cm. long, oblanceolate, dark green, sparingly hirsute and ciliate on the entire margins : heads few : disk about 1 cm. high and 1 5 mm. broad : bracts very numerous, subequal in one series, narrowly linear, fuscous, acuminate, glandular-puberulent, but not hirsute : rays very numerous, pale blue, about 8 mm. long and .5 mm. wide.
This species is intermediate between E. glandulosus and E. macranthus. It has the habit of the former, although larger, and the large heads and numerous narrow rays of the latter. It grows in wet ground, at an altitude of about 2700 m.

Rydberg (1906) published E. superbus crediting Greene for the name. No collections were cited, though a larger distribution than E. eximius was noted.

28. Erigeron superbus Greene. In the mountains of Colo. Alt. 7500-12,000 ft. Mountains near Empire; near Pagosa Peak; Minnehaha; Breckenridge ; Villa Grove; Idaho Springs; Artist's Glen and Halfway House, Pike's Peak; Box Canon, west of Ouray ; Baxter's ranch ; chaparral-covered hills southeast of Ouray ; mountains between Sunshine and Ward ; Stove Prairie Hill ; Marshall Pass.

Material designated a type of E. superbus would be C. F. Baker, #679, 15 August 1899, near Pagosa Peak, Mineral County, Colorado (GH6778, MO2616792, NY168557, RM22981, & RM160730). The database record of NY168557 showing a locality of “near Pagosa Springs” is a transcription error. The labels note that the collection was determined by Dr. Edw. L. Greene. Pagosa Peak is now in Mineral County, whereas Pagosa Springs is now in Archuleta County.

Rydberg (1906) does not mention either E. eximius or E. formosissimus, but does accept E. viscidus Rydb. (=E. formosissimus var. viscidus (Rydb.) Cronquist).

Stem retrorsely hairy; Inflorescence retrorsely hairy and somewhat glandular; Bracts somewhat reduced in size; Calyx margin scarious proximal ⅓; Corolla 18-19 mm., lavender, fading to brown tube and blue lobes; Staminode, 14 mm., glabrous proximal 9 mm., then increasingly hairy to densely hairy tip.

Weber & Wittmann (2012) will guide you to P. linarioides ssp. coloradoensis which they note is expected but not collected in Colorado. They do not accept P. teucrioides.

Ackerfield (2015) will also guide you to P. linarioides ssp. coloradoensis though based upon the hairiness of the staminode. However, per Southwest Colorado Wildflowers (https://www.swcoloradowildflowers.com) that plant is much larger, more upright, and with more broad leaves. That leaves us with the choice between P. caespitosus and P. teucrioides. I went with the latter mostly because of leaf shape, much more narrow in the latter than in the former. However, it would not surprise me if we decide the two species intergrade.

The greatest clarity comes from Harrington (1964, 2nd ed., p. 493) who specifically focuses on leaf width, i.e., “ usually not over 1.5 mm. width ” points to P. teucrioides. Harrington's description adds clarity by noting the leaves of P. teucrioides are involute, a character observed in our plant. Also with regard to the staminode, Harrington notes:

  • P. linarioides ssp. coloradoensis: barely widened distally, bearded with a rather dense tuft of hairs near the apex, very sparsely bearded proximally.
  • P. teucrioides: slender throughout, bearded most of its length.
  • P. caespitosus: slender, strongly bearded virtually its entire length.

Regardless, just a cursory review of voucher images suggests that a careful examination of vouchers of the two taxa might be called for.

Harbour.” Parry in litt. Very fine and full specimens (received as this article is going to press) are given in the recent collection above mentioned, both of the form gathered by Nuttall, with the leaves only about half an inch long and scarcely a line wide, and of a luxuriant form, with larger leaves, and flowers three fourths of an inch long on longer pedicels. The leaves on decumbent branches are all turned to the upper side, and often falcate, while the peduncles are rigidly turned to the lower side of the branch. The species is a well-marked one, and the most dwarf of the genus.

Greene (1901, v. 3, p. 23) published P. teucrioides from specimens that were not well in flower.

Pentstemon teucrioides. Suffrutescent, low, the slender tufted stems erect, 2 to 5 inches high, leafy throughout and floriferous from below the middle, the whole herbage cinereous-pubescent: leaves spatulate-linear, entire, almost pungently acute, less than 1 inch long, usually exceeding the internodes : flowers 5 or more in each subcapitate and short-pedicelled glomerule, all forming as it were a secund raceme along the upper one-half and more of the stem : segments of the calyx subulate-lanceolate, acute, entire, wholly herbaceous : narrow and strongly bilabiate deep-purple corolla about | inch long, glabrous ; sterile filament bearded almost from the base with orange-yellow hairs ; anthers glabrous.
Collected at Sapinero, 19 June; said to be common there, on dry ground, n. 186. The specimens are not well in flower ; and the aspect of the plant, particularly as to its inflorescence, is singularly like that of a Teucrium.

Greene (1899) says this about C. leptosepala and then describes C. chionophila citing Baker's collection.

C. leptosepala, DC. Syst. i. 310 ? Hook. Fl. T. x, fig. 1, doubtless. Basal leaves erect on long and rather slender petioles, round-oval, obtuse, with subcordate or subsagittate base and short rather open sinus, the margin coarsely and somewhat irregularly crenate or crenate-dentate ; the cauline one smaller, more nearly truncate at base, petiolate, inserted about midway of the stem, its stipules lanceolate-subulate, not clasping, the node indistinct, the lateral peduncle shorter and more slender than the terminal one: sepals 6 to 10, oblong-linear, obtuse: filaments linear-filiform, thrice the length of the anthers, the whole stamen surpassing the rather few pistils; mature carpels substipitate.
The plant here described answers well to the original account given of C. leptosepala, and to Hooker's figure. But still its habitat, as far as I can read it in the herbaria, is different from that assigned by De Caudolle. No such specimens are in my herbarium, nor in that of the National Museum, but there are three sheets of it in that of the Canadian Survey at Ottawa, namely, n. 1,251, from mountains south of the Zularaeen River, B. C, 27 July, 1888, collected by Dawson ; n. 1,252, Tsi-Tsutl Mountains, B. C, in swamps and marshy meadows, 14 July, 1896, by the same ; and n. 19,246, from Maclennan River, Fraser River, B. C, 31 July, 1898. They are all British Columbian specimens, and may therefore not improbably represent the real C. leptosepala.

Regretfully, Greene does not give us the etymology of “chionophila.” Stearn (2004, p. 384) states “chion- in Gk. Comp., snow-” So our plant could be known as the “Snow-loving Marsh-marigold,” and be pronounced ‘ki-on-o-PHIL-a.’

C. chionophila Acaulescent, with stoutish peduncles and scapes, and leaves thick and firm in texture, their outline from oval-subsagittate to obovate-subreniform, or even somewhat panduriform by an evident constriction below the middle, the whole margin usually coarsely and sharply dentate: earliest scapes either not equalling the leaves op little exceeding them : sepals 10 or fewer, oblong to obovate, large, the flower often 1½ inches in diameter: stamens very short, the filaments not longer than the anthers and widely dilated, of oblong outline, and even the connective subulate-dilated: mature carpels not known.
Obtained in the mountains of southern Colorado, near Pagosa Peak, at an altitude of 11,000 feet., by Mr. C. F. Baker, 28 Aug., 1899 ; and some earlier specimens in the U. S. Herbarium from southern Utah appear to be referable here, namely, those from Fish Lake at 9,000 feet, Marcus Jones, 8 Aug., 1894; also others from Marysvale, by the same collector in the same year.

Wefferling & Hoot (2017) published a key to distinguish C. chionophila and C. leptosepala.

Key to Caltha leptosepala polyploid complex
1. Leaves as broad as leaf length or broader; filaments filiform (i.e., narrower than anthers) and generally longer than carpels; in Coastal Ranges (British Columbia and Alaska), Cascades (Washington, Oregon, California), Klamath - Siskiyous (Oregon, Cali- fornia), or Sierra Nevada (California, western Nevada)
C. biflora
- Leaves longer than broad

2. Filaments broader and generally shorter than carpels; in U.S.A. Rockies or Basin and Range (Steens, Ruby Mtns.)
C. chionophila
- Filaments no broader than anthers (broadly filiform to about as wide as anthers) and generally longer than carpels; in all regions except southern Rockies

Wefferling & Hoot (2018) investigated the phylogeography of western North American subalpine marsh marigolds.

Hexaploids Caltha biflora and C. chionophila diverged in the Upper Miocene to Lower Pleistocene (chloroplast and nuclear dataset estimates overlapping at the MiocenePliocene boundary), and upon secondary contact formed allododecaploid C. leptosepala bidirectionally and at least three times.
