Diaperia candida (Torr. & A. Gray) Benth., Hook. fil. & Gen. Pl.

Diaperia candida is the most restricted of the three species, occupying most of eastern Texas (including the coast) and extending to adjacent corners of southeastern Oklahoma, southwestern Arkansas, and northwestern Louisiana.

Plants grayish silvery, 3–25 cm, densely sericeous. Stems mostly 1; branches proximal or none. Leaves: largest 10–18 × 2–3 mm; capitular leaves subtending glomerules only, or sometimes also hidden between and surpassed by heads. Heads proximal and distal, in spiciform or racemiform arrays, ± spheric, 1.5–2 mm, heights ± equal to diams. Receptacles ± spheric, 0.3–0.5 mm, heights ± equal to diams. Pistillate paleae scarcely imbricate, longest 0.9–1.3 mm. Bisexual paleae mostly 1–3, apices incurved, ± involute, gibbous. Functionally staminate florets usually 0. Bisexual florets 3–5; corollas protruding from heads, ± zygomorphic, 0.5–0.9 mm, glabrous, lobes unequal (1–2 enlarged). Cypselae rounded, ± terete, mostly 0.5–0.6 mm (bisexual slightly longer). 2n = 14.

Diaperia candida, common names silver pygmycudweed and silver rabbit-tobacco, is a plant species in the sunflower family, native to the south-central part of the United States: Texas, western Louisiana, southwestern Arkansas, southeastern Oklahoma.

Diaperia candida is an annual herb with leaves that appear silvery because of woolly hairs pressed against the surface. One plant generally has several small flower heads. Flowers bloom March to June. Its habitats include oak and pine woodlands, prairies, and coastal areas.
