We.stem Ghats and hills of South-West India from Mahabaleshwar to the Anamalai
Hills. Collected b y Ritchie at Kala Nuddi in 1852, No. 820; Brandis on Sattara Ghats,
1870; R. S. Pagan at Mahabaleshwar, 1892; "W. A. Talbot in North Kanara, Nos. 857,
905, iu 1884, also in 1889; R. C. Wroughton in Poona district and A. D. Wilkiiis in
Almednagax, 1892; Beddome in Anamalai Hills; Brandis in Coorg.
I feel sure I am right in identifying Bamhisa Ritcheyi, Mxinro, with Oxytenanthm'a
mono&tvjma, Beddome; and to this JIunro himself (see MS. note in Kew Herbarium) agreed.
The species is very well mai-ked by the velvety culms, narrow culm-sheathe, long narrow
pointed spikelets witli only one flower, and glabrous ovary and style. The leaves arc
very variable, but Brandis' specimens and Munro's descriptions agree well with those sent
b y Bombay officers, and the narrower, smaller leaves belong mostly to flowering branchlets.
INDIAN BAMBUSE^i GAMBLE. 75
Ritchie gave the vernacular name as Choomaree; Brandis' specimens boar the names Chiwa,
chiioan, chawa; Wroughton's and Wilkins' specimens those of Huda, udhe, manga, tandali.
Ritchie says it is used for basket-work ; Wroughton that it is one of the commonest bamboos
largely cut and used for all purposes, but not really veiy good. I am not sure that the
stigma is always undivided, for I have found some that separated on maceration, and I am
rather in doubt whether Munro's specific name should not have precedence. I cannot trace
this species with certainty in Dalzell and Gibson's Bombay Flora, but it may be what is
meant by the Chiivarco bamboo identified by him as Bamhusa Arimdo, Klein, Nces in
Linnoea, ix. 471, though tho description does not agree.

7. OSYTENASTHERA STOCKSII, Munro in Trans. Linn. Soc. xxvi. 130.
A slender bamboo. Culms grey-green, glabi-ous or covercd with close soft pubescence,
solid or with a small cavity, with few branches ii-om the nodes, which are
marked by a ring and soft pubescence; internodes 6 to 13 in. long. Culm-shca^hs
6 to 9 in. long, 3 to 7 in. mde at base, tapering gradually upwards and somewhat
concavely truncate a.t top; densely appressed brown h a i r y on the back, ciliate on the
margins; imperfect Made subulate acuminate, rounded at the base, and again expanded
into a rounded, waved, long-fringed auricle on the top of the sheath; liffulo lont^, •;-5
in., deeply fimbriate, conspicuous. Leaves linear-lanceolate, 4 to 8 in. long,
to '7 in. broad, rouiided or attenuate at the base into a veiy short -1 in. petiole;
at top ending in a setaceous point; glabrous above, except near the edge.s where tlie
veins are scabrous, glabrous or hairy below, scabrous on the margins; main vein naiTow
])ale, shining beneath, secondaiy veins 5 to 6 with 6 or 7 intermediate, not prominent;
leaf-sheath striate, glabrous or at first pubescent, moutli somewhat produced; ligule vaX\iex

spinous spikelets, tho heads supported b y rounded chaSy bracts ; rachis smooth, striate,
the distance between verticils 1 to 2 in. ; heads 1 in. in diameter. Spikelets -4 to -5
iu. long, narrow, glabrous, mucronate, many fertile mixed witli a few sterile. Emptij
glumes 2, ovate-mucronate, 5- to 7-nerved; then two hermaphrodite flowers; flowering ghmcs
ovate, sub-acute with a strong mucro on the back; palea of lower flower as long as
flowering glume, 2-keeled, ciliate on the keels, S-nerved between, blimt, that of upper
flower concave, convolute, blunt. Stamens long exserted, tube rather persistent; anthers
short, acute. Ovary ovoid, hairy, with a long hairy style and undivided purjjle plumose
stigma. Caryopsis not seen. Beddome Fl. Sylv. ccxxxiii.
Concan, collected by Stocks; by W. A. Talbot at Carwar in 1889, and at Coompta
River in 1884; usually cultivated.
This species is not veiy well known, but it is recognized by the acute and not
apiculate anthers and 2-flowered spikelets. I have, as did Brandis, examined many
spikelets without finding the 2- to 3-fid stigma. All I have seen are undivided. 'J'albot
gives the Kanara name as Eonda man, but says the commonest name is Mace [Mes?).
