folioso, paniculis axillaribus terminalibus-

Scirpus schenoides, Eli. Bot. S. Car. et 
Georg. v. I. p. 89. 
Culm about three feet high, triangular, 
leafy, especially towards the base. Leaves 
somewhat coriaceous, glabrous, two lines 
wide; the lower ones eight to ten inches 
in length; the upper ones much shorter, 
and.somewhat distant. Panicles four to 
five, on subexsert peduncles; the terminal 
one largest. Branches of the panicle sub- 
approximate, filiform ; the lower ones nearly 
two inches in length, with a scabrous, se- 
taceous bract at the base of each. Spike- 
lets ovate, small, rather loosely disposed 
upon the ramuli, on short pedicels, or glo- 
merate in twos and threes. Glumes fas- 
cous, broadly ovate, carinate, with a very 
short mucro. $ six, twice as long 
as the nut, strongly hispid upward. Style 
long, cleft almost to the base. Nut a little 
exceeding half a line in length, obovate, 
much compressed, deeply transversely ru- 
gose, crowned with a compressed conic 
tubercle, nearly one-third its length.

Oss. This very distinct species some- 
what resembles R. caduca ; from which, 
however, it may be readily distinguished 
by its much more numerous and 
spikelets, its strongly hispid bristles, and 
its much compressed and deeply rugose 
nut. The Herbarium of Dr. Baldwin con- 
tains specimens of this plant, with R. tz- 
In his detailed description, 
in manuscript, he has very strangely con- 
founded these three species; but the plant 
here described is doubtless the one which 
he transmitted under this name to Elliott; 
for a specimen of Scirpus scheenoides, from 
the latter gentleman, in the Herbarium of 
Dr. Torrey, agrees in all respects with our

Oss. This species is very nearly allied 
to the preceding, with which it is con- 
founded in the Herbarium of Dr. Baldwin. 
It is sufficiently distinguished, however, - 
by its nearly orbicular and less deeply ru- | 
gose nut, its shorter bristles, and patulous | 
corymbs.
