Prostrate or decumbent perennial, often suffrutescent at the base; stems 3-10 dm. long, 
simple or sparsely branched, subangulate, striate, when young densely pubescent with short, 
closely appressed, grayish, hispidulous hairs, usually glabrate in age; petioles 2-8 mm. long; 
leaf-blades oblong, oval, elliptic-oblong, or obovate-oblong, 1.5~6 cm, long, 1-2.2 cm. wide, 
usually rounded at the apex but sometimes acutish, acute or acuminate at the base, firm, 
densely pubescent beneath with short appressed hispidulous hairs, or glabrate in age, the 
upper surface soon glabrate; heads axillary or terminal, sessile or subsessile, solitary or glomer- 
ate, short-cylindric or ovoid, 12 mm. long or shorter, the flowers stramineous; bracts and 
bractlets half as long as the sepals, ovate, acuminate, long-mucronate, appressed-pilose; 
sepals 3-4 mm. long, ovate-oblong, acute, 3- or 5-nerved, densely pubescent with short hispidu- 
lous hairs; filaments linear, the tube short; staminodia ligulate, longer than the filaments, 
laciniate at the apex; style short; utricle subglobose; seed 1 mm. long, reddish-brown, shining.
