rounded or more commonly pointed at the apex, hairy on the 
back and fimbriate at the apex with a coarse white beard. Flow- 
ers about I line long. Outer perianth segments in the staminate 
flower free, abruptly acute, slightly longer and larger than the 
inner, spatulate, fuscous above and bearded. Pistillate flowers 
bearded similarly to the staminate, the lobes occasionally three ; 
ovary shortly stipitate, dicoccous; stigmas two. The heads 
appear densely villous. This species is easily distinguished from 
E. articulatum and E. compressum by its villose receptacle, and 
from £. decangulare by its smaller stature, its more slender scape, 
shorter and acute bracts, smaller heads and flowers.

I have not seen a specimen of this Texan plant, but the 
authors of the species describe it as having pellucid leaves which 
are five to seven-nerved, plane, smooth, 8 to 11 lines long and 
a little over 1 line wide at the base. Scapes numerous, 4 to 5 
inches high, setaceous, smooth, compressed, two to three-angled, 
with lax sheaths which are as long as the leaves. Heads ovoid- 
globose, about 1 % inch long, a little longer than broad. Involu- 
cral scales fuliginous, broadly obovate, irregularly denticulate and 
white-woolly above, at length slightly recurved. Receptacle 
smooth. Bracts not quite 1 line high, surpassing the flowers. 
Sterile flowers about ¥% line high; outer perianth segments 
smooth and black-glandular at the apex; inner obovate and pilose 
at the apex. Stamens four. Inner perianth segments of the fertile 
flower white-woolly on the margins. Style two-parted, plainly 
destitute of appendages. Seeds ellipsoidal, rough papillose.
