Palafoxia hookeriana
Fl. N. Amer. 2: 368. 1842.
Endemic
Annuals, 25–180 cm. Stems usually stipitate-glandular throughout. Leaf-blades broadly to narrowly lanceolate, 50–100 × 3–25 mm. Involucres broadly turbinate. Phyllaries 7–16+ × 3–5 mm, ± equal, scabrous and/or stipitate-glandular. Ray-florets 5–13; corollas 10–20 mm, laminae 9–14 mm. Disc-florets 25–90; corollas ± actinomorphic, 10–12 mm, throats ± funnelform, shorter than lobes. Cypselae 6–9 mm; pappus-scales of inner cypselae 5–8 mm. 2n = 24.
Phenology: Flowering late summer–fall.
Habitat: Sandy soils
Elevation: 10–200+ m
Discussion
Plants of Palafoxia hookeriana with stems stipitate-glandular distally (versus throughout), phyllaries 7–12 (versus 10–16) mm, and florets 25–50 (versus 50–90) per head have been treated as var. minor Shinners.
