Erigeron stanselliae is a rare species of flowering plant in the daisy family.

This wildflower has been found at only two sites in coastal Curry County, Oregon, located

new species has been found at only two sites in coastal Curry County. It was collected as early as the 1970s and 1980s, but was misidentified then as a subspecies of the well known species E. eatonii Gray. In 2009, I asked Veva Stansell, one of the original discoverers of the plant, to lead me to a known locality at Flycatcher Springs, about 13 km SE of Gold Beach. My collections from there permitted a detailed morphological comparison with other taxa of the "Erigeron eatonii-complex," especially in Humboldt and Trinity Counties, California (Chambers 2011). I was able to separate the Curry County plants from their 4 nearest relatives by minor but taxonomically important features of 1) head size, 2) degree of leafiness of the flower stem, 3) density of distal stem pubescence, and 4) presence of minute glandular trichomes on the heads. Also significant in this comparison was that the new species is limited to serpentine-derived (ultramafic) soils. The two known populations are only 5 km apart and are disjunct geographically from the 4 related taxa. I suggested that future field studies of serpentines in SW Oregon and NW California might discover more populations of this otherwise rare and highly localized species. It was a pleasure to name the plant in honor of Mrs. Stansell, whose vigorous field work over several decades has contributed a great deal to our knowledge of the flora of SW Oregon and NW California.

Plants perennial, tap-rooted, taproot slender, 1–3 mm diameter, surface striate, caudices short (rarely elongate), 1–3 surmounting taproot, surface striate or corky. Stems simple or 1(rarely 2–3)-branched medially, erect or decumbent, 7–25 cm, glabrous or sparsely strigose, leafy 0.3–0.8 times length, distal peduncle leafless, (3–) 5–10 cm, glabrous or sparsely strigose, minutely glandular beneath the head. Principal leaves in a basal rosette, entire, linear to narrowly oblanceolate, mostly 1-nerved, 4–12 cm long, 2–5 mm wide, glabrous or sparsely strigose, cauline leaves 4–8, 0.25–0.33(–0.7) times basal, gradually or promptly reduced distally, linear to narrowly elliptic, 0.5–4 cm long, glabrous or loosely strigose on both surfaces, with unicellular or few-celled, sharply pointed trichomes. Heads 1–2(–4) per stem, held well above leaves, involucres 5–6(–7) mm high, 5–10(–11) mm wide (pressed), phyllaries in 2–3 equal or subequal series, linear-lanceolate, acute to acuminate, 1-nerved, margins green (on outer) or narrowly scarious (on inner phyllaries), loosely or densely white-pilose to strigose dorsally, with under layer of minute glandular pili (Fig. 2). Ray florets 14–36, corollas 6–10 mm long, 1–1.5 mm wide, white or pinkish, curling abaxially in age. Disc florets corollas 3–4 mm, teeth deltate, acute. Cypselae 3–4 mm (immature), 2-nerved, sparingly to densely strigose; pappus of 14–24 free, minutely hispid bristles, 2.8–3.0 mm long, with a few short outer setae

Etymology, habitat, and distribution.—named in honor of Veva Stansell, long-time resident botanist of southwestern Oregon, who guided the author to the population from which the type collection was taken. The two known localities for this species, McKinley Mine and Flycatcher Spring, are some 5 km apart, north to south, near the western margin of the Siskiyou National Forest, about 11 km east and 13 km southeast, respectively, from Gold Beach.

This wildflower is native to much of the western United States where it grows in many habitats from grassland to scrub to woodland. It is a small perennial daisy reaching a maximum height of anywhere from 4 to 30 centimeters. It grows from a taproot and has hairy stems which may be erect or drooping. The leaves are narrow and lance-shaped, with three veins and raspy hairs. They are basal and also continue up the stems. Atop each stem is an inflorescence of one or more flower heads, each up to 2.5 centimeters wide. The center is packed with yellow disc florets and there are many short ray florets around the edge which are bright white, sometimes tinted blue or pink on the undersides.
