Chorizanthe pungens
Trans. Linn. Soc. London 17: 419, plate 19, fig. 2. 1836.
Plants prostrate to ascending or erect, 0.5–2 (–2.5) × 0.5–10 dm, grayish-villous. Leaves basal; petiole (0.5–) 1–3 (–4) cm; blade oblanceolate, (0.5–) 1–5 (–7) × (0.3–) 0.4–0.7 (–1) cm, villous. Inflorescences rather dense with secondary branches suppressed, grayish; bracts 2, similar to leaf-blades at proximal nodes only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 0.5–7 cm × 2–7 mm, awns 0.5–1.2 mm. Involucres 1, grayish, cylindric, often ventricose basally, 2–2.5 (–3) mm, with distinct, white to pink or purple, scarious margins extending nearly full length of awn, corrugate, villous abaxially; teeth spreading, equal, 0.5–1.5 mm; awns uncinate with longer ones 2–3 mm and alternating with shorter (1–1.5 mm) ones. Flowers exserted; perianth bicolored with floral-tube white and tepals white to rose, cylindric, 2–3.5 mm, pubescent abaxially; tepals connate less than 1/4 their length, monomorphic, obovate to oblong, acute to truncate and erose apically; stamens 9, slightly exserted; filaments distinct, 2–3 mm, glabrous; anthers cream to rose, ovate, 0.3–0.4 mm. Achenes dark-brown, globose-lenticular, 2–2.5 mm.
