The Zrora here figured has been in cultivation at Kew 
since 1889, in which year it was presented to the collec- 
tion by the late Dr. Treub, the distinguished Director of 
the Botanic Garden at Buitenzorg in Java, of which 
island it is a native, though it appears now to be very 
rare there in a wild state. The most recent record of its 
occurrence as a wild species is one by Dr. Hallier, by 
whom it was met with in a wood near Dépok, south of 
Batavia. Its nearest ally in the genus appears to be 
TI. congesta, Roxb., a native of Burma and Malaya, figured 
at t. 4325 of this work as J. Grifithii, Hook., which, 
however, differs from /. umbellata in having red flowers. 
In a tropical house at Kew J. umbellata forms a large 
branching shrub which flowers freely in May and June.
