ters, as from one root, to the number of twenty to fifty culms, scabrous, as 
are the leaves and sheaths also, and by no means easily confounded with 
C. oligocarpa, Schk.; known also long before the true oligocarpa had.

C. Careyana, Dew., grew beside the last in clusters with many culms, 
prostrate toward maturity and as it were radiating from the central root 
to the circumference of a circle three feet in diameter, or more. The 
shortness of the culm leaves strongly contrasted with those of the preced- 
ing which much surpassed the culm. : 
Not far from these was abundant, in a wet place, C. lupulina, far less 
advanced, while at considerable distance were flourishing C. intumescens, 
Edge, and C. lupulina, in close proximity, and little more advanced than 
» Grayi, 
C. Dewe ana, Schw., was also found in one dense matted oval turf of 
three feet in length and two in breadth, with the host of culms (hundreds 
at least) lying prostrate in all directions, light green; a plat of vegetable 
life more beautiful had never occurred to me. 
C. marginata, Muhl., so finely described and figured in Schk., but now 
held to be a var. of C. Pennsylvanica, Zam., is also abundant here, with 
only radical leaves which are longer than the culin, while those of the 
latter are stated to be not half so Jong as the culm. The spikes of the 
former are few-fruited, and sometimes only one or two fruit or none ma- 
tured, while the latter bear many more fruit. C. marginata should be a 
var. of the other; C. Pennsylvanica, Lam., var. marginata. 
ole 2. C. alpestris, Allion—The description of this species, by both 
Wahlemberg and Willdenow, was given in vol. vii, p, 268, of this Journal 
for 1824, hough the application there was an error, the description is 
Correct, and designates’ a species well known in Europe. The following 
Variety has been found in Texas and farther west, and is here described as 
280. C. alpestris, Allion, var, tripla, Dew. 
Staminate spike terminal, oblong, short-pedunculate; _pistillate spikes 
ee, rarely one, near the staminate, the upper sessile and the 
often three filiform peduncles, each with a pistillate spike t 
*pex, and the lowest or radical peduncle the longest and nearly equallin 
he culm; all the pistillate spikes short-oblong, loose and few-(3~10- 
 Wered ; stigmas 3; fruit oval-triquetrous, tapering at both ends, some- 
9 rather obovate, distinctly nerved, short-rostrate and beak sometimes 
» Subpubescent or scabrous, sub-alternate, sometimes equal 
anger than the oblong acuminate or mucronate scale; culm 3-8 inches. 
i ane about the length of the narrow, rough, or scabrous-pu 
te eaves, 
metimes the radical peduncles have equal length, like those of C. 
Umbellata, to which the prank was do alte vol. xxxi for 1861; but, if 
_ umbellate spikes give the character, then this may belong, as men- 
foned by Dr. Boott, to C. alpestris; perhaps it is intermediate between 
the two Species, It differs from the European form in its fruit bidentate 
and not with one-lobed orifice, longer rostrate and longer tapered below, 
and less obovate,
