A very curious spedes, which has been placed in this genus on aoceimt of its
resemblance generally to A. PrakU, especially in the solid eabns. The verv Ion»-
nan-ow sheaths are remarkable, and in its leaves it resembles OephalmtaAumn ' i t wa°8

called Bene,!, {Kkada). Mann states that it is much used, split, as a bindino- material

A ca2spitoso shrub. Culms graceful, yellow, smooth, 10 to 12 ft. high, about '5 to
•7 in. in diameter or loss, flattened on one side in alternate internodes; nodes prominent,
glabrous; iiiternodes short; branches serai-verticillate from the nodes. Cuhn-sliealhs 6 to
10 in. long, 1 to 2 in. broad, thin, papery, striate, rounded above into a short neck
and truncate, the margins produced to meet the ligule and furnished with a few
long stiff ciliaj; imperfect blade narrow, subulate, recurved; ligule long, blunt, dentate.
Leaves thin, oblong-lanceolate, 3 t o 4 in. long usually, '5 to '7 in. broad, rounded at the
base into a '1 to '2 in. long, black, hairy petiole, ending above i n a setaceous p o i n t;
smooth above, glaucous beneath, and with wlnte stiff hairs below; scabrous-serrate on
one margin; main vein prominent; secondary veins 5 to 6 pairs, intermediate about 7,
transverse veinlets very numerous, finely tessellate; leaf-shcaths loose, keeled, striate,
glabrous, eiliate on one edge; usually furnished at t h e mouth w i t h several long stiff bristles
on a short auricle; ligule rather prominent, rounded. Inflorescence a large l e a f y ]janicle
of braeteate spikes of spikelets; the bracts shoi-t, obtuse, sheathing, paleaceous with a
l e a f y imperfect blade; spikelets in each bract 3 to 5 fertile. Spikelets 1 t o 1'2 in. long,
•1 to "2 in. b r o a d ; e^npty ghmes 2, lower very large, sheath-like, bluntly truncate,
with a foliaccous green cordate blade, which becomes suialler or disappears in the
upper flowers, upper short, -3 in. long, oblique, keeled, ciHate on the keels, few-nerved,
those of upper flowers longer and more unequal sided, in terminal spikelets sometimes
w a n t i n g ; /öiücrm^ glumes ovate, acuminate, '8 in. long by '3 in. broad; main nerve
strong, secondary- 5 to 6 p a i r s ; palea about as long, narrow, 2-keeled, minutely scabrous,

emarginate or bifid, shortly eiliate, 3—7-veined, unequal. Stamens veiy long, exserted,
<li'ooping; anihars '4 in. long with the connective apiculate. Ovary depressed, ovoid,

Munro has identified Grifiith's plant with the well-known China and J a p a n species,
but apparently no flowers have been seen. I have consequently taken ray plate from
a Hongkong specimen in the Calcutta Herbarium. But G, Mann has sent leaf-specimena
of two species of PHYLLOSTACHYS, one of which seems to agree with this but
cannot bo certainly identified without flowers, and the other appears to be n ew (sec below).
Griffith described his plant as ' a small hard bamboo which forms excellent wnlking
sticks,' Mann's specimens were collected from cultivated plants found i n the Sibstigpl-
