grown in one of the beds in the central portion of the 
Temperate House, and is now a tree about forty feet high. 
This plant has been in cultivation at Kew since 1862, when 
it was presented to the national collection by Messrs. J. 
Veitch & Sons, Chelsea. Under cultivation in a greenhouse 
the species is easily kept in health, but it evidently requires 
abundant sunshine to induce it to flower, which the Kew 
plant did for the first time in June 1910, Already two 
other species of this genus have been figured in this work ; 
B. Bidwillii, Hook., at t. 5133, and B. discolor, F. Muell. at 
t. 6608,
