Erigeron canaani S. L. Welsh

Erigeron higginsii may prove to be a distinct entity. It was described as differing from E. canaani in having smaller involucres (4.5–5.5 × 7.5–11 mm) with fewer rays (7–12); it occurs at 2900–3120 m in the Pine Valley Mountains of southwestern Utah.

Perennials, (5–)10–25(–30) cm; taprooted, caudices simple or branched. Stems ascending to decumbent or nearly prostrate, sparsely strigose to glabrate, eglandular. Leaves basal (persistent, old leaf bases persistent, chaffy, fibrous) and cauline; basal blades linear to narrowly linear-oblanceolate, 50–150 × 1–2(–3) mm, cauline gradually or abruptly reduced distally, margins entire, faces glabrate to sparsely strigose, eglandular. Heads 1(–3). Involucres 5–7 × 10–13 mm. Phyllaries in 2–3(–4) series, hirsute, minutely glandular. Ray florets 15–22; corollas white to purplish, 3.5–6 mm, laminae not coiling or reflexing. Disc corollas 3.5–5 mm. Cypselae 1.8–2.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of ca. 20 bristles.

Erigeron higginsii S. L. Welsh

Erigeron canaani is a rare species of flowering plant in the family Asteraceae known by the common name Abajo fleabane. It has been found only in southern Utah, in sandy soil and in cracks on cliff faces in Washington, Kane, and San Juan Counties.

Erigeron canaani is a perennial herb up to 30 cm (12 inches) tall, producing a taproot. One plant can produce several flower heads, sometimes one per branch, sometimes in groups of 2 or 3. Each head has 15–22 white or purpleray florets, plus numerous small yellow disc florets.

The species is named for Canaan Mountain south of Zion National Park. The common name "Abajo fleabane" refers to the Abajo Mountains south of Canyonlands National Park.
