4 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
nerved, angled, ciliate on the margins and apiculate; flowering glumes similar, but larger, 
with 2 prominent nerves and intermediate: finer ones; palea 2.keeled, ciliate on the 
keels, acute or bifid at the tip, about as'long as flowering glume. Lodicules 3, obtuse, 
fimbriate, 1 smaller, 8-nerved, nerves wavy. Stamens with short filaments and obtuse 
anthers. Ovary glabrous, style swollen at the base and soon divided into two feathery 
stigmas. Caryopsis not known. Beddome Flora Sylv. ссххх. | 
Ceylon, higher hills of the north-east system of mountains in the Central Province, 
where it was collected by Mrs. Walker and by Messrs. Watson, Thwaites, and Trimen. 
Also in the Pulney Hills in South India (Beddome, 1873). 
This handsome species is recognised by its purple panicles and large thick leaves 
with cartilaginous edges. Beddome's Pulney Hill specimens (leaves only) have the 
leaves longer and nàrrower thau those fróm Ceylon, but I consider them to belong to 
this species. 'Thwaites Мо, 3860 referred to this by Munro is, I consider, true

2. ARUNDINARIA WicHTIANA, Nees in Linnea ix. 482 (1834). 
An erect, gregarious shrub with slender culms arising from short branching 
rhizomes. Culms 6 to 10 feet high, occasionally higher, dark green, turning yellowish- 
brown with age; nodes swollen and with a hairy ring below them formed by the 
bases of fallen sheaths; internodes 10 to 14 in. long, usually flattened on one side, 
prominently striate when young, usually rough; branchlets many, verticillate from the 
nodes, either of leaves only or of leaves and flowers mixed. Culm-sheaths papery, straw- 
coloured, prominently striate, 4 to 8 in. long by 1 to 3 in. broad, slightly narrowed 
upwards, covered thickly at the base and less so above with stiff golden hairs arising 
from tubercular bases; imperfect blade wavy, narrow, subulate, 1 to 1% in. long by “1 
to "9 in. broad, scabrid ; ligule short, truncate, fimbriate on the edge. Leaves of leaf- 
bearing branches 5 to 7 in. long by 75 to 1 in. broad, rounded or slightly narrowed 
at the base into a very short, somewhat swollen petiole, tip long acuminate, margins 
incurved; the edges seabrid; glabrous above, glaucescent beneath and usually glandular- 
pubescent оп Ше midrib; main veins hardly prominent above, shining below, secondary 
veins 5--Т pairs, intermediate usually 5, transverse veinlets numerous, regular, prominent 
raised beneath: those of flowering branches smaller, more rounded at the bise: 
leaf-sheaths striate, keeled, often' purple, sometimes covered with numerous strong о 
based strigose hairs, ciliate at the edges and furnished at the mouth with 5 to 8 lon 
stiff bristles ; ligule short, blunt, often dentate. Inflorescence in dense, leafy, бы 
spreading panicles, with capillary, flexuose branchlets, axils glandular. Spikelets on ig
