VANDA. 103 



The species upon which the genus was founded and the first 

 Vanda that was introduced into British gardens. It was cultivated 

 by Sir Joseph Banks in the early part of the present century, and 

 flowered for the first time in his stove at Springrove in the autumn 

 of 1819. It is common in various parts of Bengal, growing upon 

 different kinds of trees but principally on the Mango {Mangifera 

 indica) ; it also occurs on the Concan Hills in the Bombay 

 Presidency and in Ceylon. 



It was named in compliment to Dr. William Roxburgh_, one of the 

 earliest pioneers ot Indian botany and Director of the Botanic 

 Garden at Calcutta from 1797 to 1814. 



V. Sanderiana. 



Leaves 12—15 inches long and about an inch broad, complicate at 

 base, truncate, cuspidate, sometimes unequally two-lobed at apex. 

 Eacenies sub-erect, generally shorter than the leaves, 7 — 10 flowered. 

 Flowers flat, 3 J — 4| inches in diameter, the pedicels and ovary six- 

 ribbed, twisted, pale brown at the base, passing into light purple 

 upwards; bracts oblong, acute, pale yellow-green; sepals broadly obovate, 

 the dorsal one delicate rose colour sufi"used with white ; the lateral

 smaller than the sepals, coloured like the dorsal sepal with a tawny 

 blotch spotted with red on the side next the lateral sepals ; bp 

 small in proportion to the other segments, bipartite, the hypochile 

 transversely oblong, concave, with an inflexed anterior luargin, variable

This remarkable Vanda, one of the most appreciable gains to horti- 

 culture during the last decade, was discovered by M. Roebelin, the 

 energetic collector of Messrs. Sander and Co., who succeeded, in 

 1882, in reaching the previously unexplored portion of south-east 

 Mindanao, where he detected this and the scarcely less remarkable 

 Ae'rides Lawrencere and Phalcenopsis Sanderiana. Our own collector, 

 David Burke, also succeeded in reaching the same region a few 

 months later, and from that time these fine orchids became
