568 LXXVIII. GRAMINE^E. [Bambust 



attacks of Bostrichi (Roxb.) To B. Balcooa I am inclined to refer the It 

 Bamboo which is cultivated near villages in the outer hills below Simla, as high 

 as Sairi (5500 ft.), but not higher. The stems attain 40 ft., they are branchless 

 to a height of about 5 ft., the rings at the nodes are nearly horizontal, the joints 

 12-18 in. long and 3 in. diam. ; the sheaths of young shoots are large, densely 

 covered with black hairs, their breadth at base about half their length, narrowed 

 into a triangular apex, longer than broad, and about - the length of the sheath. 

 Leaves large, 9-12 in. long, 1-2 in. broad, very scabrous at edges, otherwise gla- 

 brous ; secondary nerves 7-11 on either side of midrib, not very prominent, 

 transverse veins distinct, but distant. I have never found it in flower. 



B. Falconeri, Munro 1. c. 95, is a remarkable species, described from flower- 

 ing specimens collected by the late Dr Falconer in the Dehra Doon in Sept. 

 1840. Spikelets lanceolate, wholly glabrous, nearly 1 in. long, about 10-flowered, 

 the upper 4-5, fl. male or sterile, with short effete anthers. Flowering glumes 

 mucronate, with numerous broad prominent nerves somewhat resembling those 

 of B. Tulda. Palea much shorter than glume, 2-keeled, keels fimbriate ; 7 dis- 

 tinct nerves between keels, and 2 lateral nerves on either side of keels. An- 

 thers pilose at the top, lodicules 3, with prominent longitudinal nerves termin- 

 ating in subulate teeth. Leaves, supposed by Munro to belong to the same 

 species, collected by Falconer in the previous year (Oct. 1839), and by Strachey 

 and Winterbottom at 4000 ft. elev. on Okenath in Garhwal, are 16 in. long, 3 

 in. broad, with 14 to 16 pair of prominent secondary nerves and distinct trans- 

 verse veins, concolorous and glabrous, but scabrous beneath, they resemble the 

 leaves of Dendrocalamus Hamiltonianus. The identification of the large Bam- 

 boo of the Dehra Doon and of the outer ranges between Kalka and Sairi remains 

 for farther inquiry.

Stems tall unarmed, 20-50 ft. high, green, yellow, or with green and 

 yellow stripes, joints 4 in. diam. and more, with thin walls. Leaves thin, 

 linear-lanceolate, 6-10 in. long, f-lj in. broad, very scabrous on the lon- 

 gitudinal nerves close to the edge, secondary nerves conspicuous, 6-8 on 

 either side of midrib, transverse veins numerous. Flowering stems often 

 leaf-bearing. Spikelets sessile, oblong-lanceolate, laterally compressed, 

 J - 1 in. long, glabrous, 4 - 1 2 - flowered, distichous, so that the flowers 

 of each side appear distinct, and separated by a furrow, fasciculate, or 

 in compact half-whorls on long, interrupted, paniculate spikes. Empty 

 glumes 2 ; flowering glumes ovate-lanceolate, narrowed at the base, longi- 

 tudinal nerves prominent near apex, indistinct below, mucronate and 

 ciliate at the apex, fimbriate keels of palea conspicuous near the top of 

 flowering glume. Lodicules transparent, thinly membranous. Anthers 

 penicillate at the apex, with short hairs. Style slender, filiform, 2-3-fid 

 at the end. 



Cultivated in many districts of India, particularly in the western Dekkan, 

 Kolapur, Sattara, Poona, Silhet, Cachar, Chittagong. In the eastern Panjab, 

 according to Stewart. Abundant in Ceylon, up to 2000 ft. (Thwaites Enum, 375). 

 Indian Archipelago, tropical America, and the West Indies. Commonly grown 

 in conservatories in Europe, where it not rarely comes into flower.
