Lemmon's fleabane

Navajo fleabane, tidy fleabane

Habit Perennials, 10–25(–60) cm; taprooted. Perennials, 4–25(–50) cm; taprooted, caudices simple or branched, branches sometimes rhizomelike.
Stems

decumbent-ascending to prostrate (greenish, sometimes producing erect branches), hirsute to hispido-pilose, minutely glandular.

ascending to erect, sparsely to densely hispido-pilose to glabrate, minutely glandular.

Leaves

basal (not persistent) and cauline; (greenish) proximal blades oblanceolate to obovate, 5–12 × 1–3 mm, reduced distally, margins with 1–2 pairs of teeth or shallow lobes, distal entire, faces piloso-hirsute, densely minutely glandular.

mostly basal (usually persistent) or basal and cauline (petioles prominently ciliate, hairs spreading, thick-based);

blades narrowly oblanceolate to linear-oblong, 10–50(–80) × 1–4 mm, margins entire, usually ciliate, faces usually hirsute to hirsuto-villous, sometimes substrigose to glabrate, eglandular;

cauline unreduced or gradually reduced distally.

Involucres

2.5–4 × 5–10 mm.

4–7 × 7–12(–15) mm.

Ray florets

42–60, corollas white, without abaxial midstripe, 3–7 mm, laminae not coiling or reflexing.

50–100(–125);

corollas white to pink or blue, 6–15 mm, laminae reflexing.

Disc corollas

1.8–2.4 mm.

3–5 mm (throats indurate and inflated, hirsuto-strigose, hairs biseriate, sharply pointed).

Phyllaries

in 2–3(–4) series (erect, apices appressed), sparsely piloso-hirsute, minutely glandular.

in 2–4 series (midvein region orange or yellowish), hirsute to hirsuto-villous, ± minutely glandular.

Heads

1–3.

1–5.

Cypselae

1–1.2 mm, 2-nerved, faces sparsely strigose;

pappi: outer of setae, inner of 7–10 bristles.

1.2–1.8 mm, 2-nerved, faces sparsely strigoso-hirsute;

pappi: outer of scales (0.2–0.5 mm), inner of (7–)10–14(–15) bristles.

Discussion

Of conservation concern.

Erigeron lemmonii is found only in the Scheelite Canyon, Huachuca Mountains (Cochise County), on Fort Huachuca Military Reservation. The basal portion of the stems may be “subnaked and rhizomatous in appearance, but apparently not subterranean” (A. Cronquist 1947).

Varieties 3 (3 in the flora).

Erigeron concinnus has been treated within E. pumilus; G. L. Nesom (1983b) found that these species approach each other closely in geographic range without intergradation.
