Filago dasycarpa Grisebach, Abh. Königl. Ges. Wiss. Göttingen 24: 185. 1879

Plants mostly 5–8 cm. Leaves 6–9 × 2–4 mm. Heads congested distally, mostly 4–5 mm. Bisexual corollas: lobes usually 4.

Flowering and fruiting Mar–May. Drying mud at edge of pool; ± 20 m; introduced; Tex.; se South America.

Micropsis dasycarpa is known in the flora area from one gathering (Victoria County, Gulf Coast prairie with Mimosa strigillosa Torrey & A. Gray, in 1987). For this treatment, I have assumed the Texas population to be a recent introduction; R. Barneby provided evidence that M. dasycarpa could be an overlooked amphitropical native (J. D. Morefield 2004; see also discussion under 101. Psilocarphus).
