ANACARDIACEil. 365 



1. Oncocarpus Vitiensis, Sp. Nov. (Tab. 43.) 



Hab. Feejee Islands. In a jungle at Rewa, Viti-levu. Also in 

 the Sandalwood district of Vanua-levu ; on hillsides. 



Tree 30 or 40 feet high ; the stout branches, foliage, &c, entirely 

 glabrous. Leaves simple, alternate, of a thick and coriaceous texture, 

 obovate-oblong, very obtuse, sometimes retuse, entire, or somewhat 

 undulate or repand, more or less acute at the base, from 4 to 9 inches 

 long, and from 2 to 4i inches wide, on stout petioles of 6 to 18 lines 

 in length, smooth, strongly pinnately-veined with 9 or 10 pairs of 

 primary veins which, like the thickened midrib, are very prominent 

 underneath, and inosculate near the margins ; the veinlets extremely 

 copious and finely reticulated. Stipules none. Flowers small, very 

 numerous, in a compound terminal panicle, which is minutely pubes- 

 cent. Pedicels very short. Bracts ovate-subulate, minute. Male 

 flowers. Calyx short, cup-shaped, five-toothed, puberulent. Petals 5, 

 hypogynous, oblong, acutish, puberulent outside, valvate in (Estivation, 

 with a minute inflexed apex, ividely spreading, a line and a half long, 

 deciduous. Stamens 5, alternate ivith the petals, and inserted with 

 them around the depressed, or hemispherical and hirsute torus that 

 occupies the centre of the flower : filaments filiform-subulate, rather 

 shorter than the petals: anthers oblong, emarginate at both ends, 

 two-celled, attached to the apex of the filament a little above the 

 notch at the base, introrse ; the cells opening longitudinally. Pistil 

 none. Female flowers known only from a sketch made by the bota- 

 nical draughtsman of the Expedition (copied in Fig. 5, 6 of the 

 Plate), which represents the calyx and corolla as in the male flowers, 

 no stamens, and a conical or pyramidal ovary, with 5 obtuse lobes at the 

 base, alternate with the petals, occupying the centre of the flower ; 

 the stigma sessile and truncate: its interior structure is not repre- 

 sented; but it is probably one-celled. Fruit a depressed, and as it were 

 deformed, knobby drupe, borne on a short and thickened, obconical, fleshy 

 torus (3 or 4 lines long), which is much smaller than the pericarp: 

 sarcocarp fleshy: putamen bony, depressed, irregularly sinuate-lobed 

 (the lobes about 8) one-celled. Seed solitary, conformed to the sinuose 

 cell, with a very thin integument : albumen none. Embryo transverse,
