Discovered by Sir Hugh Low in North Borneo, in 1862, and 

 introduced shortly afterwards by Messrs. Low and Co., of the 

 Clapton Nurseries; it was subsequently gathered by one of our own 

 collectors, in Sarawak, on limestone hills, at 1,000 — 1,500 feet 

 elevation, growing with Cypripedium Stonei. It is dedicated to Lady 

 Hooker, wife of the late Sir William Jackson Hooker, for many years 

 the distinguished Director of the Royal Gardens at Kew. The variety 

 Bullenianum appeared amongst an importation of G. HoolcercB by 

 Messrs. Low and Co. in 18G1-5, and is named after Mr. Bullen, 

 at that time one of their foremen, but now of the Lewisham 

 Nurseries. The usual flowering season of the species is May and 

 June, that of the variety March and April.
