 Sylv. 324. The Mephanf Grass, Vern. Iral^ Ita Kalli, Tarn. Gliats between Travancore 

 and Tinnevelli above 2,000 ft., coyering immense areas, often to tlie exclusion of almost 

 all otlier vegetation, with impenetra]3le thickets up to 15 ft. high, from which stand 

 ou^ a few scattered trees of Vernonia, Eugenia, and other kinds. Culms erect or 

 straggling, internodes 2-5 ft. long, 1-2 in. diam., walls thin. Culm-sheaths thin, 6-8, 

 blade narrow, subulate, 1^-3 in. long. L. 6-24 by 2-6 in., pet. thick, J-J in. long, 

 n. 18-21 on J in. Fl. panicles leafy, fertile spikelets few, 2 in. long, with numerous 

 sterile ones in distant heads on fascicled spikes, which are arranged in large leafy 

 panicles. Lodicules usually 3, lanceolate, more or less unequal, one dentate, sometimes 

 biiid. Stamens up to 120, anthers ^-f in. long, with a long point, filaments monadel- 

 plions, free at apex. Fr. ovoid, 3-4 in. long, 1| in. diam., fleshy, surrounded by the 

 persistent glumes and palea. Beddome collected it in fl. about 1868. T found it in fl. 

 on the Tinnevelli ghats in Feb. 1882, and in Travancore the species was expected to 

 flower in 1905. Believed to die down after flowering. Yar. hirstda, G-amble, t. 112,

 closely clasping the stem, brown hairs outside in the lower portion, blade early 

 deciduous glabrous, finely ribbed, 3-3^ in. long. Young shoots olive-brown just above

 on J- in., transverse veins conspicuous, distant, mostly oblique, sheaths green with a 

 few scattered brown hairs on the margin. Similar to Pseiidostachyum ^olymorplitmi^ 

 Munro, but reported to be tufted. 2. Sinthana, Bui-m. Pyinyaung forests, Meiktila 

 district, along banks of streams and on low, moist ground (Troup. June 1902). 

 Culms erect, clothed with light brown silky hairs, which are matted together like felt 

 near the nodes, 50 ft. high, internodes 15-24 in. long, diam. 3J-4 in., walls \ in. thick, 

 rootlets at the lowest 3 or 4 nodes. Culm-sheaths 7-10 in. long, brown-hairy outside, 

 blade persistent, ribbed on the outside. L. densely clothed with fine hairs beneath, 

 6-8 by i~| in., n. 21 on J in., transverse veins distant. 3. Tlialaw-wa, Burm. Culti- 

 vated in the Northern Shan States, 2-4,000 ft. (Troup, June 1902). Tufted, culms 

 light green, with minute white silky hairs, erect, 40-50 ft., internodes 1^-2J ft., 3-4 in. 

 diam., walls J in. thick, small branchlets at most of the nodes. Culm-sheaths thick, 

 nearly glabrous, 5-6 in. long, 12 in. wide at base, the sides curving to a slightly 

 concave top, 4 in, broad, with a brown fringe, blade triangular, on the inside densely 

 clothed with brown hairs, sharply cuspidate, base IJ in. t. 7-9 by 1 in., n. 25 on \ in , 

 transv. veins visible, oblique, distant. 4. Wamin, Burm. Cultivated in gardens in 

 the Northern Shan States, said by some to have been brought from China, by others 

 from Chengmai, in Siam (Troup, May 1902). Culms loosely tufted, erect or bending 

 stiffly up to 40 ft., usually smaller, dark green, shining and perfectly glabrous. 

 Internodes 4-6 in. long, rarely longer, much swollen in the lower half, the swollen 

 part 4-5 in. diam. Bootlets on the lowest 3 or 4 nodes. Culm-sheaths resembling
