_. CARES PROPINQUA. Mees, et Mey. in Kunth, Enum. 2, p. 396. Swamps, Mark West's Creek, 
California; April 20. No. 1622 of Coulter’s California collection. 
CAREX CHEROKEENSIS, Schw.; Torr. de Schw. Car. in Ann. Lyc. N. York, 1, p. 369, t. 25, f. 1. 
Swamps, Santa Rosa Creek, California; May 1. We can find no character that will distinguish 
this from the eastern plant. The specimens are young. The ovate abbreviate spikes and short 
bracts give it a peculiar aspect. It might be considered a var. minor. C. Cherokeensis, like all 
its allies, is very variable; from solitary to geminate and ternate spikes, (my C. Christiana, in 
Bost. Jour. Nat. Hist.) Bigelow’s specimens, if mature, would closely resemble the original 
figure of C. Cherokeensis, Torr. & Schwein. Monogr. of N. Amer. OS in Ann. Lyc. N. York,

HIEROCHLOA BOREALIS, Rem. de Schult. Syst. 2, p. 513; Hook. Fl. Bor.—Amer. 2, p. 234. 
Red-woods, California ; April 12. m" Bowie with a very short awn, or sometimes scarcely 
mucronate.

£ Arn. Bot. Beech. p. 408, non Linn. ا‎ ia, Sonoma, May 3, and Benicia, California ; 
April 23. Tt’ is No. 2028 ep Hartweg's collection. It differs from S. avenacea of the eastern 
States in its much larger flowers, the almost villous lower palea, the hairiness of the awn 
below the articulation, and in the pubescent leaves. 
AGROSTIS MICROPHYLLA, Steud. Syn. Pl. Glum. p. 164? Mark West's creek, California, May 
1. "This species was founded on a grass collected by Douglas in ** North America ;" doubtless 
in California, though it is not taken up by Hooker and Arnott in the Botany of Beechey's 
Voyage. It is Agraulus brevifolius, Nees, Mss. Our plant differs somewhat from the grass 
described by Steudel. It is rather stout than “ slender,” and is nearly two feet high. The 
leaves are flat, about two lines wide, and; as well as tlie sheaths, are quite rough to the feel. 
Panicle about three inches long, 7اا‎ the branches fasciculate and somewhat conglom- 
erate. The flowers are of a purplish tinge: Glumes ` nearly equal, lanceolate, tapering to a 
long slender point, the lower one rough on ‘the keel, otherwise glabrous ; both of them without 
lateral nerves. Lower palea less than half the length of ‘the ‘glumes, truncate, with four short 
teeth at the summit, furnished a little below the middle of the back’ with a nearly straight 
slender awn, which is nearly twice the length of the valve. Upper palea ‘wanting, Or. SS 
as a very minute rudiment. Stamens 3. Styles plumose. iie ý 
CALAMAGROSTIS GIGANTEA, Nutt. in Trans. Amer. Phil. Soc. (n. sêr.) 5, p. 148: ` Prairies and 
ravines, along the Canadian River. Glumes somewhat coriaceous,” one-nerved, the superior 
nearly 2-3 times the length of the pales, hairs at the base of the latter more ‘Kian half the 
length of the valves. Caryopsis oblong, obtuse at each end, large for the size of the spikelet;
