Annual or perennial diffusely branched stellate-pubescent herbs, with opposite entire or 
slightly undulate petioled leaves, and very small perfect 3-bracted flowers, solitary or clustered 
in the axils. Calyx of 5 equal pilose erect dry oblong 1-nerved sepals. Stamens 5, hypogy- 
nous, their filaments united at the base, their anthers 1-celled. Ovary subglobose; style short; 
stigma capitate or 2-lobed. Utricle globose, indehiscent. [Greek, branch-hair, from the

Part 2, 360. 1849. 
Perennial, somewhat woody at the base, or sometimes 
annual, stem terete, much branched, sometimes thick- 
ened at the nodes, the branches prostrate or ascending, 
4/-12/ long. Leaves orbicular, broadly ovate or rhom- 
bic-ovate, obtuse or acute, usually narrowed at the base, 
entire, inconspicuously veined, rather firm, 2//-12// 
wide, the petioles shorter than or equalling the blades; 
flowers 14’’ broad or less, mostly clustered in the axils 
of small upper leaves toward the ends of the branches. 
In dry soil, Kansas to Texas, Arizona and Mexico.

Annual, erect woolly or silky, branching or simple herbs, with opposite sessile entire or
