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. artiailatiim and E. conipressum by its villose receptacle, and 

 from E. dccangnlare by its smaller stature, its more slender scape, 

 shorter and acute bracts, smaller heads and flowers.

Herb. Van Heurck, 10 1 (1870). 

 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 1 1 lines long and 

 a little over i 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 i^ 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 i line high, surpassing the flowers. 

 Sterile flowers about y^ 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.
