 sheath, ligule a broad band of closely-packed long hairs. L. 6-9 by 1 in., 

 underside soft to the touch, with extremely minute hairs, base cuneate, 

 narrowed into a very short petiole, n. 25-30 on \ in., 1. sheaths keeled, striate 

 and with minute deciduous appressed hairs. Spikelets glabrous, blunt, \ in. 

 long, 2-3, sometimes more, in distant heads, ■§ in. across or less, supported by 

 broad, polished coriaceous bracts. Glumes conspicuously nerved, minutely 

 ciliate at edges, palese minutely pubescent. Caryopsis broadly ovoid. 



Silhet. Chittagong. Arakan. Pegu, common near streams in the upper mixed 

 forests. Martaban. Tenasserim. Flowers frequently, known to have flowered in 

 Pegu : 1862 (D. B. Zamayi), 1871 (Kurz), 1875 (D. B. Tharawadi), 1891 (Carter). The

 L. 10-14 by 1-2J in., n. 21-30 on J in. Spikelets few, heads small on long whip-like 

 spikes, the uppermost nodes bearing leaf -sheaths only, with a small blade. Sometimes 

 1 or 2 lodicules. 11. D. longifimbriatus, Gamble, t. 81. Kyaukshat and Maliwon 

 forest, Mergui district. ( Wapyaw, Burm.). Leaf-sheaths hairy, with long falcate 

 and amplexicaul auricles, thickly set with stiff curved bristles, transverse veins dis-

12. D. giganteus, Munro; Gamble, t. 76. Vern. Wabo, Burm. 



Densely tufted, evergreen, culms erect, 80-100 ft. high, usually naked in 

 the lower portion, internodes 15-20 in. long, diam. 6-8 in., walls h in. thick. 

 Culm-sheaths hard, shining within, thinly hairy outside, 15-20 in. long, 

 blade shorter than sheath, ligule stiff, dark brown, 4-i in. broad. L. 9-20 

 by 2-4 in., glaucous and minutely hairy beneath while young, n. 20-28 on

 often leafy at top, distance between heads |-f in., rachis solid, glumes 

 mucronate, 1-2 empty, 3-6 fertile, the top fl. consisting of a long, involute 

 glume. Caryopsis oblong, -^ in. long. 



Probably indigenous in the hills of Martaban. Cultivated largely in Burma, in 

 India (north as far as Makuni, Assam, D.B. Apr., 1879), and in most tropical countries. 

 The plantations of Wabo nearMyanoung (Ind. For. ii. 311) probably are of this species. 

 Used for building and for carrying water. Does not split well (M. Hill). 13.
