half of tlic fruit, tho apices of some of theni being winged as above 
described. In those inspects tho species resembles certain other 
Malayan species of Shown, e. g., S. Marduiaua Scheff, 8. scaherrima, 
and S. stenoptera^ Bnrck. Judging from the leaf -specimens on which 
Miipiel founded his H&pea Singkatcang, that plant must be a close 
ally of this. A species (flower ouly) 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 
Hot. 2681 and 3507, which form the types of Heim's species S. brachyp- 
tera, are also allied to this. 
6. Hopea, Roxb. 
Glabrous or hoary-tomentoso resinous trees. Leaves quite entire, 
firm, feather-veined ; stipules small, deciduous or inconspicuous. 
Flowers sessile or shortly pedicclled, ebracteate, in lax panicles of uni- 
lateral racemes. Sepals inserted on the receptacle, two being quite 
external and three for tho most part internal, obtuse, imbricate. Petals 
falcate, their apices inflected in bud. Stamens 15, or rarely 10, slightly 
connate ; the connective subulate-cuspidate, the anthers ovate, their 
valves obtuse, equal. Ovary 3-celled, the cells 2-ovulcd : 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 Street. — DisiiUB. of Shorea ; species about 35.
