6. GIGANTOCHLOA HETEROSTACHYA, Munro in Tran$. Linn, Soc. xxvi. 125. 
A graceful, apparently somewhat scandent, bamboo. Culms 30 ft. long, thin-walled. 
Culm-sheaths not known. Leaves linear-lanceolate, 4 to 11 in. long, "5 to 1 in. broad, 
rounded at the base into a short petiole about 71 in. long, produced above into a long, 
seabrous, twisted, setaceous point; smooth above, except the scabrous points on ko 
marginal veins, smooth below except for a few hairs ọn the midrib, scabrous on the 
margins; main vein narrow, shining, secondary veins 6 to 8, intermediate 5 to 7; 
leaf-sheaths striate, ending at the mouth in a shining callus and a rounded glabrous 
auricle, and produced beyond it to meet the ligule; ligule long, dentate, glabrous, some- 
times long ciliate. Inflorescence a large leafy panicle with spicate branches bearing 
distant few- rarely many-flowered heads in the axils of chaffy glabrous bracts ; heads 
with fertile flowers often with only one spikelet, those with sterile flowers bearing 4 to 
5; rachis smooth, striate, uppermost joints slightly pubescent, distance between heads 
from “5 up to 4 in. or more. Spikelets of two kinds: sterile “5 to ‘7 in., consisting 
of glumes sheathed one within the other; fertile 1 to 1°3 in. long, "2 in. broad, 
giabrous, oblong, compressed, with usually 1 to 3 empty glumes or with one incomplete 
flower, 4 to.5 fertile flowers and 2 to 3 terminal incomplete flowers, all on the joints 
of a persistent rachilla ; empty glumes ovate, acute or mucronate, many-nerved, glabrous ; 
flowering glumes similar, but those of upper flowers convolute, longer mucronate ; palea 
shorter than flowering glume, that of lowest (usually imperfect) flower very short, 
obtuse, 2-keeled, ciliate on the keels, 4- to 8-nerved. . Lodicules 2 to 3, oblong or 
ovate, blunt or somewhat acute, long-fimbriate. Stamens exserted, tube short and thick 
at first; anthers about 74 in. long, apiculate, the point penicillate: Ovary ellipsoid, very 
hairy, with a hairy s/yle somewhat flattened and often curved, and bearing one to three 
plumose purple stigmas. Kurz in Indian Forester 1. 345. | 
Malay Peninsula, collected by Griffith (No. 6731) near Ayer Punas, about houses. 
Тһе few fertile spikelets, which are glabrous and many-flowered, seem to distinguish 
this species. Kurz thinks it must be а Teinostachyum, but the spikelets. I have 
examined are distinctly those of а Gigantochloa, with monadelphous stamens, keeled рајеге 
and lodicules, Munro says there are three lodicules, but I have only found two, so too 
I һауе only found undivided stigmas. With this also I identify Ridley's No. 1717, 
Вија tilan, with much larger and many-flowered heads. The plate was done from 
Griffiths specimen, and does not show the head quite so large or with 80 many spikelets 
as it should perhaps do. 6. lafispiculaía with much-flattened large spikelets in heads 
of 2 to 3 only comes very near this.
