the hand-writing* of Willdenow and Schader, and it appears 
to me that there is a very considerable, if not specific distinc- 
tion, between the European and American plants known by 
the name of C. flavescens. I have not, however, ventured to 
alter the specific name at present, but will leave it for future 
consideration. The European species is a much smaller plant, 
from an inch and an half to three inches high . The spikes 
are conglomerated ; the spikelets ovate, not compressed. The 
form of the glumes likewise differs considerably. Sept. 
3. C. umbel compound, rachis angular. Spikelets bicoioi-;^ 
compressed, lanceolate, acute. Scales lanceolate, 
purple on the margin, obtuse* Pistillum long, 
bifid. Sued oval, ash coloured, smooth. Invo- 
lucrum 3'leaved, much longer than the umbeU

This plant is described, as above, by Dr. Muhlenberg, as a 
“ co-species” Spikes in a compound umbel. Spikelets lan- 
ceolate, reddish -purple and yellow. A larger species than 
No. 1. about ten inches or a foot high. In damp or wet pla- 
ces, on the borders of rivulets and springs, common. August. 
4. C. spikes oblong loose ; spikelets subulate, ex- stri§:osi^. 
panding, a little remote ; small iiivolucrums gene- 
rally v/antiiig ; partial umbels, with alternate rays..

Mr. Elliot describes tliis species as attaining the height of 
three feet. In this neighbourhood I have never seen it be- 
yond eighteen inches or two feet. Stem 3-sided, or angled. 
Leaves very long. Three or more of the leaves of the involu- 
crum generally longer than the umbel. Very common on the 
margins of swamps and ditches, and not unfrequently in san- 
dy corn-fields of Jersey, near meadow-ground. Perennial. 
August. 
5. C. culm erect nearly naked, striated, smooth tri- phymarodes, 
quetrous. Radical leaves lanceolate, sheathing at 
the base. Umbel simple or decompound. Invo^ 
lucrum 3-9 leaved, unequal, three leaves longer 
than the others, rough on the margin. Peduncles 
altogether unequal, compressed, spikelets two- 
rowed, linear, compound below, simple above, 
long 15-flowered, opposite, alternate, yellowish, 
with a linear brae tea. Caltx glume, 1-valved ob-*
