B. grandiflorum was introduced into cultivation before 
1895, when a flowering specimen was exhibited at the 
Royal Horticultural Society by Sir Trevor Lawrence. The 
specimen here figured was purchased for the Royal 
Gardens, Kew, in 1898, from Messrs. F. Sander & Co. It 
flowered in a tropical orchid house in October, 1900, and 
the flower lasted for three days.
