610 POLYANDRIA MONOGYNIA. Hopea. 



Panicles terminal, and from the exterior axills, droop- 

 ing, composed of alternate, bifarious, secund, recurved, 

 villous ramifications of numerous small, pale yellow, de- 

 lightfully fra<?rant flowers. Bractes cordate, acute, vil- 

 lous, caducous. Calyx five-leaved ; leaflets unequal, 

 ovate, villous, pennanent, the two largest increasing 

 into tAvo large oblong, obtuse, membranaceous wings, 

 by the time the pericarpium is full grown. Corol one- 

 petalled; contorted. Tube short, campanulate. Border 

 of five oblique, sublinear, oblong, spreading divisions, 

 with their margins revolute, curled, and somewhat vil- 

 lous. Filaments ten, about as long as the tube of the 

 corol, and inserted by broad, conicnl, fleshy bases, into 

 its bottom, alternately larger and bifid. Anthers fifteen, 

 tvvo-lobed, with a subulate point from the apex of each, 

 or as in Asarum the anthers may be said to adhere to 

 the filaments below their apices. Germ superior, ovate, 

 three-celled ; cells three-seeded, attached to the top of the 

 axis. Style straight, the length of the stamens. Stigma 

 simple. Capsule ovate, pointed, one-celled, evalvular, of 

 a tender texture, closely enveloping a single seed of the 

 same shape and size, outwardly covered with the per- 

 manent calyx, two of the leaflets of which are now 

 enlarged into two linear oblong, obtuse, tough, mem- 

 branaceous, nervous wings, many times longer than the 

 seeds. 



The above described tree is nearly allied to my Shorea, 

 as well as to the wood oil tree, Dipterocarpus of the Ma- 

 lay Islands, Pegue and Chittagong. It differs from the 

 first in having only two of the five leaflets of the calyx in- 

 creasing into wings, in having a more petalous corol, and 

 from Shorea in the stamina. 



I am inclined to think Dammara selanica, Rumph. 

 Herbar. Amb. vol. 2. p. 168. t. 56, is of the same na- 

 tural order, particularly as in some parts of India, very 

 large quantities of a resinous substance are also collected
