DIPTER O CARPEM. 



\^l 



A gigantic timber-tree, with alternate, entire, parallel- 

 veined leaves, loose terminal and axillary panicles of yellow, 

 hermaphrodite, regular flowers, and enlarging (accrescent) 

 calyx-lobes. 



Fig. 112. Sal [Shorea robust a), about one-half or one-third natural size. 



Observe the remarkable enlargement of each of the lobes 

 of the calyx after flowering in Dipterocarpus and Hopea 

 only two become enlarged : hence the name of the former 

 genus and of the Family, significant of the two-winged fruit. 

 In some species of Dipterocarpus the wings attain several 

 inches in length.
