half of the fruit, the apices of some of them being winged as above 

 described. In these respects the species resembles certain other 

 Malayan species of Shorea, e. g., 8. Martiniana Scheff, 8. scaberrima, 

 and &. stenoptera, Bnrck. Judging from the leaf-specimens on which 

 Miquel foivnded his Hopea 8ingkaivang, that plant must be a close 

 ally of this. A species (flower only) collected by H. 0. Forbes in 

 Sumatra (Herb. No. 2952) must also be closely allied to this. It 

 differs however by its conspicuously bracteolate inflorescence. Beccari's 

 Nos. 2681 and 3507, which form the types of Heim's species 8. brachyp- 

 tera, are also allied to this. 



6. Hopea, Roxb. 



Glabrous or hoary-tomentose resinous trees. Leaves quite entire, 

 firm, feather- veined ; stipules small, deciduous or inconspicuous. 

 Floivers sessile or shortly pedicelled, ebracteate, in lax panicles of uni- 

 lateral racemes. Sepals inserted on the receptacle, two being quite 

 external and three for the most part internal, obtuse, imbricate. Petals 

 falcate, their apices inflected in bud. 8tamens 15, or rarely 10, slightly 

 connate ; the connective subulate-cuspidate, the anthers ovate, their 

 valves obtuse, equal. Ovary 3-celled, the cells 2-ovuled : style shortly 

 cylindric or subulate. Fruit 1-seeded, closely surrounded by the bases 

 of the accrescent sepals, the 2 external of which are developed into 

 linear wings, the three internal not longer than the ripe fruit. Embryo 

 as in Shorea. — Disieib. of Shorea ; species about 35.
