This leaves, as the oldest unoccupied name, H. opacum of Torrey & Gray, which 
accordingly reappears as a specific name. 
tt Placente projecting a little, or not at all: sepals unequal. 
= Leaves mostly linear, with rather large and scattered pellucid dots: flow- 
rs in somewhat lealy-bracted cymes: capsule conical or globose; seeds large, 
oval, strongly rugose transversely. 
13. H. spherocarpum Micux. Simple or branched, 1 to 3 
feet high: leaves linear to narrowly oblong, mostly obtuse, 2 to 3 
inches long, 3 to 6 lines wide: eyme loosely- flowered, dicho- 
tomal flower mostly sessile : sepals varying from small and linear

Rocky banks of the Ohio and its tributaries, southward to Arkansas. 
This stands as a very good species, easily distinguished from any likely to 
be confounded with it, by its strictly one-celled capsule and large very rough 
s. In fact, the seeds are the most ch everett fth g 
mistake the specific name has been often written H. spherocarpon, while the 
original name is as above. 
14. H. dolabriforme Vent. Low, straggling, 6 to 18 inches 
high: leaves linear to linear - lanceolate, widely spreading, about 
an inch long, a line or two wide, mostly acute: cyme few-flowered, 
dichotomal flower pedicelled: sepals large and foliaceous, lance-

Ovate-conical, almost triquetrous, about 3 lines long, coriaceous.
