Indian Canyon Fleabane

Rays of Erigeron untermannii tend to both coil and reflex, emphasizing its apparent close relationship to E. caespitosus. The leaves are often spatulate and glabrous to glabrate abaxially, features more similar to E. radicatus and its close relatives. Hybrid parentage is a reasonable hypothesis.

Perennials, 2–8 cm; taprooted, caudices branched, retaining old leaf bases. Stems erect (greenish proximally, essentially scapiform), strigose, eglandular. Leaves mostly basal (persistent); blades oblanceolate to spatulate, 10–50 × (1–)2–5(–7) mm, sometimes continuing on proximal ¹ / 2 of stems, margins entire, faces usually sparsely to densely strigose, abaxial sometimes glabrous or glabrate, eglandular. Heads 1. Involucres 5–7 × 6–12(–15) mm. Phyllaries in 2–3(–4) series, densely hispiduloso-hirsute, eglandular. Ray florets 14–30; corollas white to pink or purplish, 4–8 mm, laminae coiling and reflexing. Disc corollas 3.5–5 mm. Cypselae 2.3–3 mm, 2-nerved, faces and margins moderately strigose to strigoso-sericeous, margins densely ciliate; pappi: outer of setae, inner of 18–35 bristles.

Erigeron carringtoniae S. L. Welsh

Erigeron untermannii is a North American species of flowering plant in the family Asteraceae known by the common name Indian Canyon fleabane. It is native to the western United States, only in the state of Utah.

Erigeron untermannii grows in sunny locations in sagebrush and in open coniferous woodlands. It is a small perennial herb rarely more than 8 centimeters (3.2 inches) tall, producing rhizomes and a branching underground caudex. The inflorescence is made up of only one flower heads per stem. Each head contains 14–30 white, pink, or purple ray florets surrounding numerous yellow disc florets.
