Catalina Tarweed

Deinandra clementina is known only from six of the Channel Islands (Anacapa, San Clemente, San Nicolas, Santa Barbara, Santa Cruz, and Santa Catalina).

Subshrubs or shrubs, 15–80 cm. Stems ± solid (floccose in some leaf axils). Leaves: proximal blades toothed or entire, faces pubescent to somewhat canescent, ± hirsute, strigose, or scabrous, often stipitate-glandular. Heads usually in crowded, corymbiform or paniculiform arrays. Bracts subtending heads usually overlapping proximal 0–¹/2+ of each involucre. Phyllaries ± evenly stipitate-glandular (sometimes sparsely), including margins and apices, often with non-glandular, pustule-based or non-pustule-based hairs as well. Paleae in 2 series (1 between ray and disc florets, 1 between outermost and adjacent disc florets). Ray florets (11–)13(–20); laminae deep yellow, 4.5–7 mm. Disc florets 18–30, all or mostly functionally staminate; anthers reddish to dark purple. Pappi of 7–10(–15) lance-linear, fimbriate scales 1–3 mm. 2n = 24.
