Plants 10–30 (–40) cm; scape glabrous. Caudices not obvious at anthesis; roots white; bulblets absent. Leaves 4–20 (–23) × 1.5–4 (–6) cm; petiole usually slender (at least basally); blade broadly elliptic to ovate, base slightly decurrent onto stem, abruptly tapering to petiole, margins sinuate to dentate, surfaces glabrous. Inflorescences 1–6-flowered; bracts narrowly lanceolate, 3–8 (–10) mm, glabrous. Pedicels 1.5–4.5 (–5.5) cm, glabrous. Flowers: calyx light green, 4–6 mm, glabrous, tube 2–3 mm, lobes 5, 2.5–4 mm; corolla-tube yellow with red, thin, wavy ring, lobes 5, usually white, rarely lavender, 13–20 mm; filaments distinct, whitish yellow to yellow, 0.6–1 mm; anthers 6.5–8 mm; pollen-sacs purplish to reddish purple or yellow, often streaked with red, connective yellow basally, smooth; stigma not enlarged compared to style. Capsules tan to light-brown, valvate, narrowly ovoid, 9–13 × 3–5 mm, glabrous; walls thin, pliable. Seeds without membrane along edges.


Phenology: Flowering late spring–summer.
Habitat: Moist, usually shady slopes in oak and conifer woodlands
Elevation: 2400-3100 m

Discussion

Dodecatheon ellisiae occurs in two disjunct locations. In north-central New Mexico, it is found in the mountains of Bernalillo, Sandoval, and Torrance counties. In southeastern Arizona, it is known from the mountains of southern Apache (White Mountains), southern Graham (Pinaleno Mountains), Greenlee, and northeastern Santa Rita (Santa Catalina Mountains) counties. On the Graham Mountains in Arizona, the corolla lobes may be lavender. Plants in Arizona and Chihuahua have yellow stamens with some red speckling. It is not known if this is significant taxonomically; it does suggest a shift in pollinators.
