A NEW SPECIES OF DURIO FROM BURMA

W. SOEGENG REKSODIHAEDJO *)

In working up the sterculiaceous specimens from the Herbarium of
the Indian Botanic Garden in Calcutta I have encountered a specimen of
Durio which represents apparently a hitherto undescribed species. The
description of this species is presented here. Gratefully I acknowledge my
thanks to the Director of the Calcutta Herbarium for the loan of the
specimen together with the excellent drawing from which the figure
published here has been copied partly.
