INDIAN ВАМВОЗЕЖ; GAMBLE. 59 
'9 in., striate, many-nerved with conspicuous transverse veinlets, sparsely hairy outside, 
one at the base of Ше spikelet, the other above; lowering glume similar, “7 to 1 in. 
long; palea of lower flowers longer than flowering glumes, narrow, 2-keeled, ciliate on 
the keels, 3- {о ó-nerved and hairy between the keels, divided often one-fourth of the 
way down into long hairy tails separated by a sinus, that of the uppermost flower not 
keeled or ciliate, not, or only slightly, cleft, glabrous except the acute tip, many-nerved 
and transversely nerved; rachilla hairy. Lodicules 2, lanceolate, acuminate, ciliate, very 
thin. Stamens long exserted, drooping, filaments purple, anthers yellow, the connective 
produced in a blunt point. Ovary yellow, depressed-turbinate, stalked, surmounted by 
a long style, bearing 3 broad feathery stigmas. Caryopsis about 74 in. long, glabrous, 
cylindrical, with a somewhat broader top, spongy below, ending in a long beak formed 
by the persistent base of the style; pericarp crustaceous, shining above. 
Hills of. Upper Burma in moist forests on ridges at 2,000 ft. elevation. A large 
handsome bamboo of which the stems are greatly in request for building purposes and the 
seed of which is eaten. It flowered in 1891. Our specimens were colleeted by Mr. J. W. 
Oliver, Conservator of Forests, or by Messrs. Allan and Lowis under his orders. It has 
also been collected by Abdul Huk in the Shan Hills for the Caleutta Royal Botanic 
Garden. The bracteate, loose inflorescence, deeply-cleft lower pales and long entire 
upper ones at once distinguish this genus of two species, and this species is readily 
recognized from the other by its larger size in all respects. It is called Thanawa in Burmese 
and Mui‘ong by the Kachins. А considerable quantity of seed has been collected and 
distributed, and many seedlings have been raised and planted in Dehra-Dun and 
elsewhere. I have only found two lodieules, but I expect the third is also often present.

9. THYRSOSTACHYS SIAMENSIS, Gambie. 
A very graceful, cespitose deciduous bamboo. Сийиз 25 to 40 ft. high, straight, not 
branching till high up, 1:5 to 3 in. in diameter, usually covered with the persistent old 
culm-sheaths, otherwise greyish-green ; nodes not prominent ; internodes 8 to 11 in. long, 
with a white ring below the nodes, Culm-sheaths 9 to 11 in. long, 4:5 to 8 in. broad, 
soft, thin, covered with fine white appressed риђевсепсе on the back, striate, attenuate 
upwards to а wavy truncate top, about 15 in. broad, produced at the margins into short 
triangular auricles; imperfect blade 4 to 5 in. long, narrowly triangular, the edges 
recurved ; ligule narrow, 1 in. broad, glabrous, finely ciliate. eaves narrow, linear, 3 to 
6 in. long, "З to "5 in. broad, rounded or attenuate at the base into a very short (:05 
in. long) petiole ; points short, twisted; glabrous on both sides, or slightly pubescent 
beneath when young; scabrous on one edge ; main vein narrow, secondary veins 3 to 
5, intermediate 6 to 7; Jeaf-sheaths striate, white pubescent and ciliate, truncate, and 
ending in a glabrous callus; ligule very short, ciliate; branches after flowering often 
producing tufts of wiry branchlets, with very small leaves. Inflorescence a large,
