sepals. Nuts or drupes about half as loug as the calyx, minutely pubesceut, 

 with a thin epicarp and crustaceous endocarp. Embryo in the seeds examined 

 as much curved as in Cadellia, but the cotyledons narrower.

Flowers hermaphrodite. Calyx small, 4- or 5-cleft. Petals 4 or 5, almost 

 valvate. Disk hemispherical or cupular. Stamens 8 or 10, with a small 2- 

 cleft scale at the base of the filaments. Ovary globular, entire or shortly

 albumen' scanty ; cotyledons folded towards the middle. — Trees, usually armed 

 with prickles. Leaves alternate, compound. Elowers small, in pedunculate

 Branches glabrous, often armed with short conical prickles, usually m pairs, 

 one on each side of the leaf, but probably not really stipulary. Leaflets 3, 

 ovate, acuminate, 1|- to 3 in. long, the lateral ones petiolulate and oblique at 

 the base, the terminal cue narrowed at the base ; all glabrous or sprinkled 

 with a few hairs underneath. Flowers small, few together in axillary cymes, 

 on slender peduncles, shorter than the leaves. Calyx and petals quite gla- 

 brous. Filaments hairy at the base. Drupe small^ depressed, globular, fur- 

 rowed between the nuts.

Order XXX. BURSERACEiB. 



Flowers regular, hermaphrodite or polygamous. Calyx usually small, 3- 

 to 5-lobed or divided into as many distinct sepals. Petals 3 to 5, hypogy- 

 nous or perigjmous, imbricate or valvate in the bud. Stamens twice as many 

 as petals, or rarely of the same; number, inserted on or around the disk ; an- 

 thers versatile, with 2 parallel cells opening longitudinally. Disk usually 

 annular or cupular, often adnate to the base of the* calyx. Ovaiy free, 2- to 

 5-celIed, tapering into a single style, with an entire or lobed stigma. Ovules 

 2 in each cell or rarely solitary, usually pendulous, the micropyle superior. 

 Fruit a drupe, eitlier indehiscent or the epicarp opening in 2 valves, pyrenes 

 2 to 5, bony or chartaceous, distinct or united. Seeds solitary in each py- 

 reue, pendulous; testa membranous; albumen none. Cotyledons usually 

 membranous,^ folded or rarely thick and fleshy .—Shrubs or trees, often yield-
