bracts, hairy at the base and ciliateon the edges, the spikelets іп verticillate clusters 
on thin, wavy, scabrous, hairy pedicels; rachis hairy, flattened оп one side. 
Spikelets 1 to 1:5 in. long, narrow, with 2 empty glumes and 4 to 6 flowers ; 
rachilla long, 2 to °З in., flattened, hairy, ciliate at the clavate top; етріу glumes 
2, ovate-lanceolate, mucronate, 5- to 7-nerved, scabrous, hairy оп the back ; flowering glume 
9 in. long, lanceolate, long mucronate, scabrous, hairy above, 7-пегуед; palea nearly 
as long, bimucronate, 2-keeled, ciliate on the keels. Lodicules 3, obovate, faintly nerved, 
long ciliate, one rather shorter and narrower. Stamens apparently not exserted; anthers 
emarginate, the connective not produced, but the cells crowned with a few very fine 
white hairs. Ovary linear-oblong, glabrous, with a very short style and 2 long 
plumose stigmas. Caryopsis not known, 
Khasia and Jaintia Hills of Assam: collected by Griffith at Moflong in 1835; by 
Hooker in 1850; by C. B. Clarke at Sohra, 4,500 ft. in 1872; and by G. Mann on 
the Mangot river near Jowai, Jaintia Hills, at 3,500 ft. in 1889 and at Nungklaw, 
Khasia Hills, at 3,000 ft. in 1890. 
This species is distinguished from А. callosa, the other thorny species, by its quite. 
different inflorescence, smaller leaves and peculiar culm-sheath. The woolly nodes of the 
culms and branchlets and the hairs on the apices of the anthers are, however, the best 
general characters. As stated by Munro, it seems to have only once been collected in 
flower, namely, by the Assam Deputation under Wallich and Griffith for the examination 
of the tea plant. The Khasia name is Ahnap (С. Mann); but Mann’s Khasia specimen 
bears the name U-spar, which is also that of A, callosa. The culms are used for 
tying the thatch of native houses. |

10. ARUNDINARIA CALLOSA, Munro іп Trans. Lian, Soc. xxvi. 30. 
A shrubby thorny bamboo. Culms 12 to 20 ft. high, % to 1 in. in diameter, grey- 
ish-green, smooth, striate when young; nodes raised in a ring which is subtended by. the 
base of the fallen sheath fringed with soft brown hairs, and which is studded with 
short thick conical spines, the said spines breaking through the sheath when the latter 
is detached; internodes 6 to 10 in. long, nearly solid at base, the walls higher | up rather 
thin, (15 in. in thickness), Culm-sheaths as long as or longer than the internodes, 
loose, thin, striate, smooth, transversely veined, ciliate on the edges, gradually attenuate 
upwards from а softly hairy base to a 2 in. truncate tip; imperfect blade 5 to 1 in. 
long, subulate, hairy without and within, decurrent on the sheath in long-fringed short 
auricles; ligule *l. in., fimbriate. Leaves 8 to 9 in. long, * to 13 in. broad, oblong 
lanceolate, thin; somewhat unequally attenuate at base into a 1 to E in. long 
petiole. which 18 swollen at its base; ending above in a scabrous, acuminate point; 
finely glandular-scabrous above, especially . on the marginal veins, райе and pubescent 
beneath; scabrous-serrate on the edges; main vein prominent, shining, hairy on the 
upper. surface; secondary: veins 5 to 8 pairs conspicuous; intermediate 5 to 6; transverse
