94 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
imperfect blade 4 to 6 in. long, broad, triangular, cuspidate, appressed-hairy beneath, 
rounded at the base, and then again decurrent in broad. wavy auricles fringed with few 
deciduous bristles; ligule narrow, *1 in. broad, white-hairy outside. Leaves oblong-lanceolate, 
19 to 14 in. long, 15 to 18 in. broad, unequal at the base, and narrowly attenuate into 
a short "1 in. petiole; above long acuminate, with a twisted, scabrous, setaceous point; 
glabrous above except the scabrous points on marginal veins, shortly pubescent beneath; 
scabrous on the edges; main vein conspicuous, shining, secondary veins 10 to 16, 
intermediate 5 to 7, pellucid glands many, giving the appearance of strongly marked 
tranverse veinlets beneath;  /eaf-sheaths glabrous or slightly hairy, ending in a broad 
shining callus, straight truncate at the mouth; ligule short. Inflorescence a large compound 
panicle with spicate branches bearing heads of sterile and fertile spikelets with chaffy 
bracts; rachis usually fistular, striate. Spikelets up to 2 in. long with 1 to 2 empty or 
gemmiparous glumes, 5 to 6 fertile flowers, and 1 to 2 terminal imperfect flowers ; rachilla 
obcuneate, striate, minutely ciliate at top; empty glumes ovate-acute, mucronate; flowering 
glume ovate-lanceolate with a broad base, acute, glabrous, sometimes with a soft sub- 
foliaceous point, many-nerved; palea ovate, 2-keeled, scabrous, toothed on the keels, 
5-6-nerved between them, tip glabrous or penicillate. | Lodicules almost obovate, long- 
fimbriate, many-nerved. Anthers narrow, penicillate at the apex. Ovary ovate, acute, 
hairy above, with a short style and З long hairy stigmas. Caryopsis not known. Munro

in Assam by Jenkins. 
Very little is known of this plant except the original sheets in the Kew Herbarium. 
But I believe I am right in identifying with it No. 1001 collected by С. Mann in 
1391 at Charduar in the Durrang district of Assam, though the spikelets are not quite 
so long, and the rachis not so soft and fistular as in the type. I also think that 
С. Mann’s Bhaluki-makal (Assamese) collected in Sibsagar in 1889, is this species. Не 
says it is а soft-culmel kind easily attacked by insects, and consequently not much

Culms and culm-sheaths not known, Leaves 19 to 14 in. long, 1:5 % 2 in. broad, 
oblong-lanceolate; unequally narrowed at the base into a short 2 in. broad petiole; 
ending above in a subulate seabrous point with the margins recurved, sometimes con- 
tracted below the tip; slightly seabrous above, especially on marginal veins, smooth 
beneath; edges not seabrous; main vein narrow, shining, secondary veins 10 to 12, 
not conspicuous, intermediate 3 to 5; leuf-sheaths appressed, hairy, somewhat keeled, 
ending in a narrow callus, and truncate at the edges where they meet the ligule; ligule 
2 to :3 in. long, very deeply cleft in the middle into two elongate rounded lobes, 
bearing long stiff ciliz. — Јодотезсетев on long spicate leafy branches bearing very
