Root iiemuial stem 6-12 inches high, leafy throughout, ending in a thyrsus of 
small, white, loosely corymbulose flowers. The stem and edges of leaves are 
usually smooth ; but sometimes the leaves are either papillate or ciliate on the 
edges, and the stem, especially in its upper half, more or less densely clothed with 
defiexed cartilaginous hairs. Flowers scarcely 1 line long. C. acuminata, E.

along the truncate apex with long white hairs ; stem simple, scapelike, 
with opposite subdistant leaf-scales below, angular, floriferous above ; 
cymules capitato-fasciculate, sessile in the axils of opposite, scale-like 
bracts, forming a long spicate-thyrsus ; calyx-lobes short, ovate, nerved,

The specimens are in an advanced state, with withered leaves. Leaves nume- 
rous, 1-2 inches long, with a spathulate petiole, expanding into a shortly cuneate 
lamina, 1-1} inch broad, abruptly cut off at top, and fringed with rigid hairs 2-4 
lines long. Flowering stem 12-18 inches high, more than half of it occupied by the 
spiked inflorescence, whose tufts are $—1 inch apart. A remarkable species.
