ANACARDIACEiE. 367 



coriaceous, dull ; the stout petiole half or two-thirds of an inch in 

 length. Panicles in the axils of the leaves at the summit of the 

 branch, branching, loosely many-flowered, slightly pubescent under a 

 lens, exceeding the leaves. Pedicels shorter than the flowers. Calyx 

 glabrous, persistent, five-cleft; the lobes broadly ovate, obtuse, slightly 

 if at all ciliate, probably imbricated in aestivation . Petals 5, scarcely 

 2 lines in length, ovate-oblong, recurved-spreading, deciduous. Sta- 

 mens 10, rather shorter than the petals, and inserted with them : 

 filaments subulate : anthers oblong, somewhat sagittate. Disk cumu- 

 late, exceeding the calyx, with the base of which it is scarcely cohe- 

 rent, thick and fleshy, the thinner edge minutely many-toothed. Pistils 

 usually 5, half immersed in the closely encircling disk, slightly hairy, 

 one (or sometimes 2 or 3) of them obliquely ovate and ovuliferous ; 

 the others fusiform and effete. Styles scarcely any : stigma terminal, 

 thickened, very obtuse. Only the immature fruit is known ; in which 

 two or three of the ovaries sometimes enlarge and become more or less 

 coherent at the base : probably only one of them is fertile. 



The plant here described well accords with the character and an 

 imperfect original specimen of Schauer's B. florida, from Manilla, ex- 

 cept that the flowers are larger, and the lobes of the calyx show 

 scarcely a trace of minute ciliate hairs. — From the ticket, I perceive 

 that Mr. Rich supposed our plant to be the Rhus atrum of Forster, a 

 New Caledonian species, which has obovate and coriaceous leaves, 

 indeed, but bears its (probably pentandrous) flowers in a dense, spi- 

 cate-crowded inflorescence, much shorter than the leaves.
