stout, rigid, smooth, ten to fourteen-angled, 1 to 3 feet high. 
Heads 4 to 8 lines in diameter. Involucral scales ovate, often 
eroded, dentate at the apex and hairy below. Receptacle hairy, 
the hairs under the microscope many-celled, appearing acute at 
the apex or very rarely club-shaped. Flowers about 2 lines 
high, densely woolly at the base, the bract larger than the 
flowers acute, white-bearded. Perianth segments spatulate, 
white-bearded.

4. ERIOCAULON RAVENELII, Chapm. 
£. Ravenelit, Chapm. Fl. 503 (1860). 
Very smooth throughout. Leaves linear, very acute, flat, 
thick or thin and pellucid, finely five to ten-nerved, somewhat 
longer than the sheaths. Scapes slender, 4 to 5 inches high, 
clustered, five to six-sulcate. Sheaths obliquely fissured, acute, 
nerved like the leaves. Heads 1 to 2 lines in diameter. 
Involucral scales scarious, light straw-colored, oblong, very ob- 
tuse. Bracts a little narrower than the scales, often obtusely 
pointed and denticulate, fuliginous. Flowers scarcely more 
than 4% line high, fuscous, smooth. Segments of the outer fer- 
tile perianth separate, very slender, mucronately pointed; of 
the inner somewhat broader, minutely toothed. Ovary sessile ; 
style parted into two stigmas. Chapman states that the style is 
occasionally simple and the seeds minutely pubescent. The spec- 
imens which I have examined failed to show either.

E. Texense, Korn. Linnea, xxvii. 595 (1854). 
Scapes smooth, 8 to 10 inches high, six to seven-sulcate, slender, 
in the specimens examined solitary. Leaves acuminate, many- 
nerved, fenestrate, flat, smooth, 1 to 2 inches long, a little shorter 
than the sheaths. Roots fibrous, the larger ones nodose. Heads 
hemispherical, 1 to 2 lines in diameter. Involucral scales 
obovate or nearly orbicular, smooth, entire, straw-colored. Re- 
ceptacle pilose with silky hairs. Bracts as long as the flowers, 
cuneate or obovate, the upper part livid, the lower whitish,
