hairs rise in the vagina. Repens, Lam., arenarium (no. 476. ib.), and 
paludosum, Roxb. (no. 465. ib.) have blunt glumes, and live in water.

ribus 5-9-nerviis ciliatis, superioribus 3-nerviis. 
Deserta; Punjab.

ligula membranacea paleacea. Culmi glabri, erecti, 1—3-pedales.

superior bifida aristata, arista locustam æquante.  Lodicule grosse 
eroso-truncatz, subbidentate. - Flosculi 3 pedicelli dense pilosi, pilis.

There are several forms very much resembling one another, and 
which have been confused together in herbaria. This species 
differs from all in the plane, not convolute, leaves.  Circinatus, 
Hochst. (Steud. Gr. no. 294, p. 387) differs from all in the indu- 
rated polished glume. | Oliverii, Boiss. (no. 295. ib.; Desf., 288. ib.) 
has rough convolute leaves, longer than those of laniger. The 
pedicel and rachis have hairs equalling the floscules. The glumes 
are 5-nerved. Laniger (from Algiers) has much shorter convolute 
leaves, the pedicels not quite reaching to the floscules. The 
glumes 7—11-nerved. 
There is another species, abundant in the lower Himalaya, dif- 
fering in having longer, linear convolute leaves, spikes defracted, 
with much shorter hairs in the pedicels, and scarcely aromatic— 
almost the same as the Persian Oliverii. 
ARISTIDA (CHZTARIA) HYSTRICULA. Pusilla, glabra, gluma superiore 
acutata inferiorem ovulatam mucronulatam subduplo superante. 
Sindh and Multan. (Stocks, No. 187 partim.) 
Spithameea, pallescens. Culmi graciles, glabri, striati. Vaginze breves, 
ore pilis albis, longe ciliate. Folia glabra, convoluta, pollicaria. Pa- 
nicule breves, pauciflore. Gluma inferior ovata, acuta, carina serru- 
lata in mucronem abeunte (2-linealis) ; superior sublvis, linearis, in 
mucronem hispidulum acutata (3-33-linealis), quandoque fissa. Flos- 
culus hispidu]us, arista non articulata, stipite 8—10-lineali, setis sub- 
zqualibus 1-1$-pollicaribus hispido-scabris. 
The habit is very unlike Hystrix (Linn.fil.; Steud. Gram. no. 99, 
p. 141), though the technical description is too much like.
