E. SIMPLEX, p. 306. The specimens numbered 410 of 
Drummond's New Orleans collection seem to belong to this 
species; buttlieyare too young to be determined satisfactorily. 
E. TENUIS, p. 309* Mr. Arnott, in a very recent letter, in- 
forms me that the printer of Nees' Cyperaceae, made a mistake 
respecting Scirpidium tenue. According to the Mst. the syno- 
nym ought to be, " S. tenuis, ^Nluhl. ex parte, nee S. tenuis, 
Willd. et Link." It is also " S. tenuis, herb. Endlich. e Con- 
necticut." The specimens which Nees examined are immature, 
and he remarks of the species " Fructus deest. Specimena non 
sufficient." So that his plant may still be identical with his 
Eleocharis tenuis. Nees was probably led into error by 
Muhlenberg's inaccurate description of this species. 
E. MELAXOCARPA, p. 311. I havc received specimens of 
this rare species from Mr. Groom, who collected them no a 
journey from Middle Florida to Georgia. On carefully ex- 
amining the style, I find that it is two-cleft, and remarkably 
hairy, particularly about the bifurcation. The culm is rather 
striate than sulcate, and the nut is blackish when mature. The 
spikes are somewhat acute in many of Mr. Groom's specimens.
