Malay Peninsula in Penang and northwards to Tenasserim, according to Munro,
though Kuvz doubts it; much cultivated in Burma and in the gardens of Calcutta,
Madras Peradeniya in Ceylon, and elsewhere; also in the Palm-house at Kcw. Specimens
were gathered by D. Brandis at Maknm ia Assam in 1879 from cultivated plants.
I t was also collected at St. Helena by Mr. D. D. Monis.
This species is probably the giant of the bamboo tribe, and is at once recognized
by its size, its characteristic sheaths, and the long whip-like spikes of the panicle, with
long spikelets, acuminate anthers, and bifid palea. Good pictm-es of a magnificent spedmen
in the iloyal Botanic Gardens at Peradeniya, Ceylon, with its young shoots
appeared in the Gardener's Chronicle for 10th September 1893. In Burma it is known
as ' WaW (the 'Wa-ya' referred to this by Mum-o is, Brandis infonns me, D. longispatJms,
Kurz). An account of the plantations at Jlyanoung on the Irawadi is given in Ind.
Forester ii. 311, where it is said that the plantations have 15 to 20 clumps per acre
and that good culms fetch Rs. 1-4 each. The Assam name is Worra. It flowered in
the Calcutta Botanic Garden in 1860-61 and again in 1888; in Burma iu 1892, whonco
it was sent by W. T. McHarg from Tenasserim and by Abdul Iluq from the Shan
Hills; also in 1893 by H. Jackson from the Wyelat in the Southern Shan States.

A tufted bamboo. Culms with appressed silvery hairs, thickened and annulate at the
nodes. Culm-sheaths covered with appressed tawny haii-s, truncatc at the mouth; Uguk
narrow, entire, or nearly so. Leaves large, those of the end branches broadly lanceolate
acuminate; rounded at the base into a very short petiole; 9 in. to 1 ft. long by 1 to 2-5 in.

on the edges ; secondary veins 9 to 13 on either side, faint; leaf-sheaths striate, long
white-ciliate at tJie edges, ending in a small callus below the petiole and truncate at the
mouth; ligule broad, truncate, entire or shortly sen-ate. Injloreseence a large panicle of long,
whip-like, curved spikes; spikelots clustered in heads of 2 to 5 with a few small empty
bracts at base; rachis between the heads 0-5 to 3 in. long, flattened on one side on

by TDr. John Anderson at Poneshee and Bhamo in 18G8, and on the Yunan Expedition
in 1875.
Recognized by its long flagellate spikes and clusters with few spikelets, resembling
most the inflorescence of D. giganteus. Kurz says that there are lodiculcs, but I have
not found them.

A large bamboo with ciespitose culms, reaching 60 ft. in height, loaves borne only
on upper branches. Culms glaucous-green when young, greyish-green when old
