Lindley to contain the species having a clavate pseudobulb 
bearing leaves only at the apex, and a terminal or lateral 
inflorescence. The section was not recognized by Bentham 
and Hooker, but after excluding two or three species now © 
known to belong elsewhere it forms a well-characterized 
section of Dendrobium. The genus is remarkably poly- 
morphic, and is now estimated to contain at least five 
hundred species, these being distributed from Japan, 
China, and Northern India to New Zealand. 
Descr.—Au epiphytic herb about a foot high. Pseudo- 
bulbs 4-10 in. long, narrow at the base, with several 
somewhat imbricating sheaths, clavate above, somewhat 
compressed and sulcate, about 1 in. broad, 2-leaved at the 
apex. Leaves ovate-oblong, subobtuse, coriaceous, 34-44

the base, 4-5-flowered. Bracts ovate, subacute, somewhat 
concave, over $ in. long. Pedicels 14-2 in. long, smooth 
and slender at the base, upper part and ovary densely 
villous with reflexed hairs. lowers cream-white, with a 
few purple streaks at the base of the lip. Sepals spreading, 
about J+ in. long; the dorsal one elliptic-lanceolate, 
acuminate ; the lateral pair obliquely triangular, acuminate,
