CYMBIDIUM. 13 



native of Nepal^ but this habitat has not been confirmed by its 

 discovery in that country since its first introduction. It has re- 

 appeared at intervals in several orchid collections both in this 

 country and on the contiaeutj and the plant may still be in 

 cultivation. It is very near Gymbiclium canaliculatum, a circumstance 

 which suggests an Australian origin. 



0. Devonianum. 



Stems obscurely pseudo-bulbous, each witli 3 — 5 leaves. Leaves 

 broadly strap-shaped, acute, 7 — 12 or more inches loug, narrowed below 

 into a channelled petiole about one-fourth as long as the blade. 

 Eacemes stoutish, as long as the leaves, quite pendulous, sheathed at 

 the base with 3 — 5 brown membraneous boat-shaped scales. Flowers 

 numerous, 1 — l^ inch in diameter ; sepals and petals similar, ovate- 

 lanceolate, variable in colour, sometimes olive-green spotted with purple, 

 sometimes buff-yellow streaked with vinous purple, the petals shorter 

 and more acute than the sepals ; lip obscurely lobed, shorter than 

 the other perianth segments, broad ovate or sub-cordate ; the blade 

 reflexed, sometimes deep sanguineous purple, sometimes light rose-purple 

 with a darker blotch near each lateral margin. Column bent, with 

 two small rounded wings, greenish yellow with some red spots at the 

 apex.

Originally discovered by Gibson on the Khasia Hills^ and intro- 

 duced by him to Chatsworth in 1837, but where it did not flower 

 till the spring of 1843. Gibson found it growing on the trunks 

 of decayed trees and in the forks of the branches of old trees 

 where some vegetable matter had accumulated. It was next 

 gathered by Sir J. D. Hooker and Dr. Thomson on the Kollong 

 Rock in the same region, at 5,000 feet elevation. The Kollong 

 Rock is a very remai'kable geological phenomenon ; it is scarcely 

 less interesting from a botanical point of view, on account of the 

 number and variety of the orchids found on it and in its immediate 

 vicinity. A brief account of it, extracted from tlie Himalayan 

 Journals of Sir J. D. Hooker, may be suitably introduced here: — 

 " The Kollong Rock is a steep dome of red granite, accessible from 

 the north and east, but almost perpendicular to the southward, wliere 

 the slope is 80° for 600 feet. The elevation is 400 feet above the 

 mean level of the surrounding ridges, and 700 feet above the bottom 

 of the valleys. The south or steepest side is encumbered with
