with Goodenough that they were distinct species. As they 
are found in the same marshy situations and often associa- 
ted, and are possessed of different and constant characters, 
they may be considered distinct. 
Like C. paniculata, it is often dioecious and polygamous. 
But it may be distinguished from it by its less diffuse spikes 
scarcely panicled and of a darker brown ; by its fruit which 
is darker colored, and rather more rounded or gtbbous at. the 
base, convex on the upper and slightly concave on the under 
side towards the tip, and more distinctly scabrous than C. 
paniculata. :

This isa very distinct species. Four to ten inches high— 
leaves sub-radical, bristle-form, and rather pale-green—one 
staminate spike, often very nearly sessile, and frequen 
rising to a less height than the pistillate—pistillate spikes 
two or three, on peduncles, the a two rising nearly Md 
the same level, about five flowered—fruit ovate or slightly 
obovate, black when mature, longer than the ovate whitish 
scale—bracts white, membranaceous, hyaline, scarcely half 
the length of the pedunele, obliquely truncate. It agrees
