Saccolabium violaceum (Mr. Harrison's variety). 



sub-var. — Mr. Harrison's (Bot. Mag. t. 5433. Williams' Orch. Alb. V. 

 t. 23G), perianth segments wholly white, column green, anther yellow. 



Discovered by Curomg- near Manila^ and sent by liim to Messrs. 

 Loddiges^ of Hackney, about 1840. It is now known to be quite 

 common throughout the Phihppine Islands^ always occurring in hot, 

 damp valleys, often on the Mangroves growing in the swamps 

 along the coast. The sub-variety was communicated to the Royal 

 Gardens at Kew in 1863 by Messrs. Low and Co,^ who imported 

 it from the island of Pulo-copang in the China Sea (not found on 

 any map within our reach), and named it in compliment to 

 Mr. C. H. Harrison, " a gentleman greatly interested in the intro- 

 duction and cultivation of Indian orchids." The nearest affinity of 

 Saccolalnum violacewm is the Burmese 8. giganteum, from which it 

 differs chiefly in the form of the labellum. It usually flowers in 

 the early spring.
