Agoseris heterophylla var. quentinii

G. I. Baird

Sida 21: 271. 2004.

Common names: Arizona agoseris
Treatment appears in FNA Volume 19. Treatment on page 334. Mentioned on page 333.

Stems 0. Leaves spreading to prostrate; blades 2–12 cm × 3–9 (–12) mm, mostly lobed, lobes 2–3 pairs, abaxially glabrous, adaxially pubescent. Peduncles 0–26 cm, lengths mostly less than 0.5 times leaves at flowering, 0.5–3 times leaves in fruit, ± glabrate, or apically tomentose. Florets 15–30+; corollas ± equaling phyllaries at flowering, tubes 2–3 mm, ligules 2–3 × 0.8–1.5 mm; anthers ca. 1 mm.


Phenology: Flowering Mar–Jun.
Habitat: Mesic to dry habitats in deserts, grasslands, and oak woodlands
Elevation: 1200–2000 m

Discussion

The relatively small corollas and anthers of var. quentinii suggest that it, too, may be autogamous, as is var. heterophylla.
