ciliatis, foliis linearibus patulis glabris, paniculze ramis distantibus erecto- 
patentibus, spiculis patulis szepissime geminis, una sessili, altera pedicel- 
lata. 
A perennial, with slender erect glabrous stems about 3 feet 
long, branched low down. Sheaths 2-3 in. long, densely ciliated 
on the edges towards the top; blade acuminate, moderately firm 
in texture, 4-6 in. long, 1-3 in. broad, glabrous both on the sur- 
faces and margin. Panicles several to a stem, terminal and from 
the axils of the leaves, reaching a foot in length, with distant 
erecto-patent branches, the lower 2-3 in. long. Spikelets usually 
in pairs, spreading, lanceolate, glabrous, 4 in. long, one sessile, 
the other shortly pedicellate. Glumes lanceolate, acute, gla- 
brous, not aristate, the two outer about half as long as the spikelet, 
5-nerved on the back.—Central Madagasear, Baron 1061! Two 
species of this genus are already known, which are confined to 
the Himalayas, China, Japan, and the Malay archipelago. 
BROMUS DISSITIFLORUS, nh. sp. 
Perennis, glaber, caule elongato, foliis paucis elongatis anguste lineari- 
bus, panicule laxissimze ramulis paucis ascendentibus, spiculis paucis 
pedicellatis 7—8-floris, glumis sterilibus parvis lanceolatis, floribus segre- 
gatis, gluma florifera lanceolata 5-nervata breviter aristata. 
A perennial, glabrous in all its parts, with slender erect stems 
2-3 ft. long. Basal leaves several, with a linear setaceous convo- 
lute lamina reaching a foot in length. Stem-leaves about four, 
with tight sheaths 2-3 in. long and a linear blade sometimes 
half a foot long. Panicle very lax, nearly a foot long, with few 
distant solitary ascending branches, bearing each 2—4 spikelets, 
the side ones on ascending pedicels 2-2 in. long. Spikelets 
à in. long; sterile glumes lanceolate, unequal, j-] in. long; 
flowers erecto-patent, distinctly separated from each other on 
the slender glabrous axis ; flowering glume lanceolate-navicular, 
3 in. long, green, glabrous, obscurely 5-ribbed, narrowed gradu- 
ally into a very short terminal awn.— Central Madagascar, Baron 
2092! Allied to B. pectinatus, Thunb., and B. scabridus, Hook. 
fil., and amongst European species to B. sterilis. 
BROMUS ARRHENATHEROIDES, n. sp. 
Perennis, glaber, caule elongato, folis paucis elongatis lineari-setaceis, 
panicule laxz ramis multis ascendentibus, spiculis paucifloris lateralibus 
sessilibus vel breviter pedicellatis, glumis sterilibus magnis lanceolatis tri-
