and the glabrous calyx of Dipterocarpus affinis, the smaller seg- 
ments in flower reflexed, and not erect as represented in Korthals’s 
figure of D. Baudii. Vidal, Sinopsis, Atlas, tab. 14. fig. D, 
represents a fruit of what he calls D. pilosus, from the island 
Alabat (Tayabas), with the smaller segments of the fruiting-calyx 
erect, which agrees with the fruit of D. pilosus from Assam and 
of D. Baudi; from Sumatra. 
A leaf of D. elongatus, Korthals, flowers and fruit of which are 
unknown, from Borneo in Herb. Kew, agrees well with D. affinis, 
and it is not impossible that more complete specimens of the two 
species may show their identity, in which case Korthals's name 
will take precedence.
