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 rotinded or gibbous at the 

 base, convex on the upper and slightly concave on the under 

 side towards the tip, and more distinctly scabrous than C. 

 paniculata.

The following description is translated from Willd. Sp, 

 PI. Staminate spike solitary , peduncled j pistillate in pairs, 

 peduncled, about five Jioxoered ^ fruit obovate-globose, striate, 

 beaked, obliquely truncate j bracts membranaceous, sheathing 

 and hyaline. 



It is found in the mountain woods of Austria, he. It has 

 been found in our country only at the foot of the limestone 

 hills in Pownal, Vt. 



This is a 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 frequently 

 rising to a less height than the pistillate — pistillate spikes 

 two or three, on peduncles, the upper two rising nearly to 

 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 peduncle, obliquely truncate. It agrees 

 with the fig. in Schk. and with the popular account irt 

 Rees' Cyc.
