Dipterocarpus Gaertn. 



1. Dipterocarpus lasiopodus Perk. n. sp. Tree 30 — 40 m high (ex 



Merrill), young branches densely hirsuto-tomentose. Leaves 

 coriaceous, elliptic, oblong or ovate- oblong, on the upper sur- 

 face glabrous, on the lower surface glabrous except at the 

 sparsely pubescent midrib, margins undulate, nerves on both 

 sides very prominent, veins parallel at rightangles to the nerves, 

 midrib depressed above, prominent beneath; length 12 — 23cm, 

 width 6 — 12 cm; petiole 3,5 — 4 cm long, densely hirsute, 

 consisting of tufts of stellate hairs, some short some long. 

 Stipules 4 cm long, 9 mm wide, externally densely hirsuto-to- 

 mentose. Fruit ovoid, wings 13 cm long, 2 cm wide; tube of 

 the fruiting calyx with 5 protuberances in its upper portion. 



Luzon, Prov. ofTayabas, Guinayangan, growing on sandy 

 soil, sandstone (Merrill no. 2031 with fruit in April), (Merrill 

 no. 2004). 



The nearest ally of this is Dipterocarpus Warbiirgii 

 Brandis, from which, however, it differs by having smaller fruit. 

 In D. lasiopodus the densely hirsute -pubescent petiole is most 

 peculiar. Mekrill says that the wood of this tree is used for 

 bancas (native canoes) and that the tree occurs frequently in 

 forests.
