OF THE DIPTEROCARPACEA, 39 
inspersa.  Petioli pilis stellatis longis fasciculatis fuscis obtecti. 
Flores.. ..... Fructus turbinatus, alis 5 crassis rigidis. 
Island of Basilan, South Philippines ( Vidal, n. 2160). 
Blade 7-11, petiole 2 in. long. Secondary nerves 18 pairs; 
tertiary parallel and reticulate. Differs from Dipterocarpus gran- 
diflorus in the short petioles, the tomentum of long hairs on young 
shoots, and the thick, not membranous, edge of the fruit-wings. 
Sect. V. Prrcamr, Dyer (slightly modified). 
Margins of two adjoining fruiting-calyx segments, which are 
continued into the fruit-wings, remaining separate for some 
distance, uniting lower down and forming the 5 wings of the 
fruit. These wings are transversely plicate. 
55. DrPTEROCARPUS INTRICATUS, Dyer in [ London] Journ. Bot. 
(1874) 105 ; Pierre, Fl. Forest Cochinch. fasc. 14, t. 215. 
Gregarious on sandy soil in the plains of Cochinchina. Delta 
of the Mekong river, 16 miles from the coast, extending to the 
limit of sweet and brackish water in the river (Warburg). 
The inflorescence of this species is remarkable. Different from 
most other species of this genus, it consists of unilateral racemes,a 
pair of large oblong-falcate membranous 5-nerved bracteoles being 
at the base of the short pedicel, which stands in the axil of these 
bractlets. Two such racemes, each bearing 6-8 flowers, stand 
at the end of the peduncle, and the common peduncle apparently 
ends in a solitary terminal flower, which, however, is nothing but 
the lowest flower of one of the two collateral racemes. An exa- 
mination of fresh specimens or material preserved in alcohol can 
alone settle this interesting point. o. 
Contrary to Mr. Dyer’s opinion (l. e. p. 153), I place D. intri- 
catus under this section. In D. lamellatus the wings, decurrent 
from the margin of the two adjoining calyx-segments, unite at the 
base of the frnit, here they unite below the apex. The difference 
is only one of degree, pedicel and base of fruit in both species 
have 5 wings only.
