 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

ERIGERON COMMIXTUS. With the habit of E. flagellaris, smaller, less stoloniferous, the leaves relatively broader, some entire, others with one or more conspicuous lobes at base of the blade, the whole plant almost hoary with a stiffly hirsute pubescence, this spreading on the leaves and petioles, retrorse on the stems and peduncles : heads, rays, achenes, etc., much as in E. flagellaris.

Canon of the Limpia, mountains of western Texas, 26 April, 1902, S. M. Tracy and F. S. Earle; also collected by the present writer, in the same general region, namely, in the mountains near Silver City, New Mexico, 18 May, 1880, and distributed for E. flagellaris. The species last named has a rather obscure, fine closely appressed hairiness. That of the new one is so extremely different, that were the plants of the size of a Sunflower or Goldenrod, no botanist would confuse them as one species, were the pubescence the only character. I may remark that true E. flagellaris reaches the mountains of even southern New Mexico, where, however, it occurs only in a more elevated biological zone.

We now treat E. commixtus as a synonym of E. tracyi.

ERIGERON TRACYI. Allied to the last but dwarf, only 2 or 3 inches high, densely leafy at base and with no stolons (at least at flowering time): petioles of the spatulate-lanceolate entire leaves shorter than the blade or obsolete; the whole herbage silvery-hoary with a fine dense strigulose pubescence, or this more sparse and spreading on the solitary scapiform peduncle: involucre hispidulous: outer pappus very conspicuous though consisting of only shorter and setiform hairs, the inner of a few very delicate capillary ones.

Davis Mountains, western Texas, Tracy and Earle, 28 April, 1902.

FLAGELLARE (sp. nov.): bienne ? striguloso-puberulum, pumilum; caulibus gracillimis e basi ramosis, floriferis seu primariis simplicibus superne aphyllis monocephalis, sterilibus patentibus flagelliformibus; foliis spathulatis mucronulatis inferioribus in petiolum gracilem attenuatis integris seu radicalibus parce inciso-lobatis, ramealibus parvulis sublinearibus sessilibus; ligulis numerosis gracilibus (albis purpureo tinctis) involucrum hirsutum duplo superantibus; pappo radii et disci conformi duplici, exteriore coroniformi-squamellato conspicuo, interiore e setis sub-20 fragilibus. Low, moist places, along Santa Fe Creek; May, June. (381.) -- Root slender. Flowering stems 5 to 7 inches high, very slender, few-leaved below the middle, naked and pedunculiform above; the head rather smaller than in the preceding species; the involucre, &c., similar. Lower leaves one to two inches long, including the slender petiole; those of the runner-like sterile branches decreasing to 2 or 3 lines in length. This species should rank next to the foregoing.

The “foregoing” was Erigeron cinereum (sp. nov.), now treated as a synonym of E. tracyi Greene. The head was described as “ as large as those on Bellis perennis ” and the involucre was described as “ hirsutum duplo superantibus ” [ coarse erect or ascending hairs doubly ??? ]

1682  Field identification: Potentilla norvegica.

This turned out to be a mixed collection of similar taxa in Potentilla Sect. Rivales. FNANM shed some light on this section:

The North American representatives of sect. Rivales are morphologically distinctive in being annuals, biennials, or short-lived perennials (especially in cold regions) with very short, conic-tapered styles. Plants grow primarily in wet habitats, especially where periodically inundated. These distinctions led E. L. Greene (1906c) to adopt Tridophyllum. However, the gross morphological cohesiveness is not matched by molecular monophyly. Instead, chloroplast data scatter Potentilla norvegica, P. rivalis, and P. supina among the core Potentilla, while P. biennis is sister species to the monophyletic Ivesia-Horkelia-Horkeliella clade (C. Dobe and J. Paule 2010; M. H. Tpel et al. 2011). Nuclear markers, on the other hand, place P. norvegica as sister to the Ivesia-Horkelia-Horkeliella clade (Tpel et al.), suggesting a possible hybrid origin and/or multiple origins of the biennial habit.

Existing herbarium annotations of Potentilla biennis, P. norvegica, and P. rivalis are not reliable, but the three species can be readily distinguished by vestiture of proximal petioles and stems. Only P. biennis has prominently septate gland-tipped trichomes; P. norvegica is characterized by relatively stiff, spreading, tubercle-based hairs to 3 mm, resembling those of P. recta. In addition, the tiny, smooth, pale achenes of P. biennis and P. rivalis contrast sharply with the larger, darker, strongly ridged ones of P. norvegica.
