GENERA. 
I. DRYOBALANOPSEZÆ. 
1. Dryobalanops Garrn.—Flowers hermaphrodite, receptacle 
rather concave. Sepals 5, slightly connate and perigynous at base, 
subequal imbricate. Petals 5, alternate, sometimes very slightly 
coalescing at base, contorted. Stamens , o-seriate; filaments 
short; anthers introrse; cells 2, linear; valves equal, connective 
apiculate. Germen free, almost entirely superior, 3-locular ; style 
slender entire, apex stigmatiferous not thickened ; ovules in each 
cell 2, collaterally descending; micropyle extrorse superior. Fruit 
capsular subligneous semi-included in accrescent base of calyx, lobes 
subequal, wing-shaped accrescent ; pericarp finally 3-valved at apex. 
Seeds 1 or more rarely 2 ; cotyledons of embryo exalbuminous, fleshy, 
very unequal, contortuplicate, the larger involving the smaller; radicle 
superior thick, vertical, pericarp intruded in false dissepiments between 
folds of embryo and laterally sub-2-winged.—A glabro ous resinous 
camphorous tree ; leaves alternate Dee entire coriaceous, crowded 
lineate-penninerved ; stipules minute or scarcely seen ; flowers at the 
summit of twigs or in axils of upper leaves, cymose-racemose ; each 
2-bracteolate (dndian Archipelago). See p. 210. 
2. Dipterocarpus Garry. ¥.'—Flowers outwardly irregular; 
summit of receptacle usually slightly concave. Calyx free, gamose- 
palous ; tube free, 5-fid or 5-dentate at apex ; lobes very unequal ; 
larger generally 2; all when young slightly imbricated ; afterwards 
valvate or open. Corolla contorted and stamens ©, slightly 
perigynous (of Dryobalanops) ; anthers elongated, cells linear introrse 
rimose ; connective more or less produced beyond cells, acuminate. 
Germen inferior at base 3-locular (of Dryobalanops), style slender, 
apex entire or shortly 3-dentate. Fruit dry subwoody, indehiscent,
