Usually tufted, but the rhizome often with long creeping branches whick 

 send up tufts of culms at a distance from the parent clump. Principal 

 branches flattened above the axillary bud, hence angular, branches few (2-3) 

 from each node. L. tesselated with numerous prominent transverse veics, 

 forming squares with the n., sheath loose. The Indian species frequently 

 have the uppermost 1. apparenth^ in pairs, the internodes between these 1. 

 being very short. Panicle terminal, leafy, spikelets sessile 1-4-fld., in the 

 axils of large imbricating bracts, the bracts often with a small leafy blade. 

 Empty glumes 2-3, palea 2-keeled, many-nerved, often bimucronate, stamens 

 3, style long with 3 long feathery stigmas. Species about 30, Eastern Asia. 



1. p. assamica, Gamble MSS. Mishmi hills, forming extensive patches covering 

 the hillside, 10-11 ft. high, makes excellent walking sticks (GriiEth MSS. Notes and 

 Journals, p. 38). Namdang, iLakhimpur district, Sadiya. Also cultivated near 

 Sibsagar. Culm-sheaths straw-colour, at the base of the narrow blade with narrow 

 oblong auricles, covered with long bristles, transverse veins prominent on the inside 

 of culm-sheaths. L. thin, linear-lanceolate, 4-6 by ^-f in., pet. slender J in. long, 

 n. 36-42 on J in., leaf-sheaths long bristly-ciliate at mouth. FL unknown. Following 

 Munro, Gamble in Bambusese united this with Fhyllostachys lambusoides, Sieb. et Zucc. *, 

 Gamble t. 27, but he has since informed me that in his opinion the Indian plant is 

 distinct.

 the Naga hills. Cult, at Bernardmyo, Upper Burma, brought from China. Mai pang

 stems are flat on one side, and some of the 1. are in pairs, pet. slender, J in. long,

 Gamble under Arundinaria elegans, collected by J. Anderson on the Yunnan expedi- 

 tion at Poneshee in 1868, 1. | in. wide, n. 45 on i in. A specimen mentioned by 

 Gamble in the same place, collected by G. Gallatly (746), Tenasserim 5,000 ft., I have 

 not seen.
