PHAIUS ALBUS. 



it was afterwards discovered in Silhet, by Francis de Silva, who was employed to 

 collect plants for the Botanic Garden of Calcutta. 



It requires a hot and moist stove when growing, but should be kept cool, and 

 more dry when dormant. The soil should be rough sandy peat mixed with small 

 potsherds. 



It may be increased by division in the spring, just before it begins to grow. 



The generic name Phaius is derived from <pai.bs, brown, the first-discovered 

 species being of that colour. The specific name albus has reference to the white 

 flowers. The dissection shows the column, at the base of which is the adnate 

 labellum.
