species, are coriaceous and have 10 to 13 pairs of nerves. The Perak plant 

 may therefore belong to a distinct, hut closely allied, species. Curtis' 

 Penang specimens (Xo. 1401) are quite glabrous in all parts except the 

 petals. 



8. Dipterocarpus OBLONGiFOLius, Blume, Mus. Bot. Lugd. Bat. II, 

 36. A tall tree : young branches glabrous, dark-coloured, sparsely 

 lenticellate ; buds cylindric. Leaves coriaceous, oblong or elliptic- 

 oblong, shortly and bluntly acuminate, the edges sub-undulate, the 

 base cuneate ; both surfaces shining, glabrous, the midrib and 13 to 16 

 pairs of straight bold nerves with a few stellate hairs along their 

 sides : length 6 to 8 in., breadth 2 to 275 in., petiole "9 to l'l in. 

 Racemes slightly supra-axillary, densely tawny- torn entose, bifurcating, 

 each branch with 3 to 5 flowers and several linear membranous decid- 

 uous bracts. Flowers about 2 - 5 in. long. Calyx-tube fusiform, slightly 

 contracted at the mouth, 1 in. long, boldly 5-angled, densely stellate 

 tawny-tomentose as are the 3 minor calyx lobes ; the 2 larger linear - 

 oblanceolate lobes sparsely stellate-pubescent, boldly 1-nerved and with 

 2 obscure lateral nerves. Bipe fruit unknown. Miq., PI. Ind. Bat. I.

Perak, Scortechini. Distrib. Borneo, Sumatra. 



Except as regards inflorescence, the Perak specimens of this are 

 practically glabrous. In Bornean specimens, however, the young parts, 

 buds and petioles are fusco-tomentose. (Dyer 1. c.) 



9. Dipterocarpbs grandiflorus, Blanco, Fl. Filipp. Ed. 2, 314. 

 A tree 80 to 120 feet high: young branches rather stout, sub-compressed, 

 at first hoary-puberulous, but finally quite glabrous, nearly black when 

 dry ; leaf-buds shortly ovoid, minutely pale-canescent. Leaves coriaceous, 

 ovate-elliptic, shortly acuminate ; the base broad, rounded or sub-truncate, 

 sub-cordate ; the edges entire or obscurely undulate-crenate, both sur- 

 faces glabrous; main nerves 14 to 16 pairs, spreading, rather straight, 

 prominent on the lower, obsolete on the upper, surface ; length 6 to 9 

 in., breadth 3'5 to 5 in. ; petiole 2 to 3 in. long, glabrous. Racemes 

 about 4-flowered. Flowers articulated to the rachis, 2 in. long. Caly.v- 

 tube 5-winged from base to apex. Petals linear-oblong. Fruit oblong, 2'5 

 in. long, wings stout, *5 in. or more in width ; the 2 accrescent lobes of 

 the calyx oblong, obtuse, glabrous, reticulate, 3-nerved, the mesial 

 nerve the longest and most distinct, 7 to 9 in. long and 1"5 to 2 in. broad, 

 the smaller calyx lobes sub-orbicular. A. DC. Prod. XVL, 2 p. 612;
