1. B. coccineus, Schum. et Thonn. PL Guin. 226. A copiously 

 branched shrab 4 or 5 ft. high, with glabrous, terete, dark-coloured, woody 

 l)ranches mottled with copious, pale, raised spots. Petiole | in, long, firm, 

 slightly downy when young, the rachis 2-3 in. long ; leaflets in 3-5 pairs, 

 obovate, the lateral ones alternate, on very short petiolules, about I in. long 

 by ^ in. broad, the point rounded and emarginate, the lower side cut away 

 slightly towards the base ; texture subcoriaceous, both sides glabrous when 

 mature, the lower a little downy when young. Flowers in copious, lax, 3-5- 

 flowered cymes, the peduncle very short, the pedicels very slender, glabrous, 

 often |— ^ in. long, with small lanceolate bracts at the base. Calyx at first 

 campanulate, 1 line deep, the lobes reaching two-thirds down, ciliated, orbicu- 

 lar, much imbricated, finally quite patent, \ in. deep and the lobes then scarcely, 

 if at all, imbricated. Corolla white, 3-4 lines long, the petals equal, under 

 1 line broad. Stamens all equal and equalling the corolla or alteraately 

 longer and shorter and the longer ones falling short of the corolla, with inter- 

 mediate gradations. Carpels densely grey-silky. Pod about ^ in. long, ob- 

 long-cylindrical, very slightly stalked, glabrous, brown, coriaceous, a little 

 curved, finely grooved longitudinally. — Planch, in Linnaea, xxiii. 412 ; Walp.

After examination of a large number of specimens, it is quite clear to us that no de- 

 pendence can be placed on the length of the filaments as a specific character, and that there 

 is no definite limit between the 3 species published from the W. coast. 



2. B. orientalis. Baker. A small tree with very rugose glabrous branches 

 mottled like those of the preceding. Petiole f-l in. long, firm, glabrous, the 

 rachis 6-8 in. long; leaflets in 10 or 12 nearly opposite pairs arid a terminal 

 one, the lateral ones on stalks under 1 line long, oblong, \-\\ in. long by 

 about half as broad, the base equally rounded, the point blunt and slightly 

 mucronate ; texture subcoriaceous, both sides glabrous. Plowers as in the 

 preceding. Petals (not seen in our specimens), according to Baillon, obovate 

 and much imbricated. Pruit-calyx deeper than in the preceding (2 lines), 

 the lobes subdeltoid. Pod ^-f in. long, slightly curved. — Rourea orientalis,

 Also a plant of Madagascar, from whence M. Baillon (1. c.) has described 2 additional 

 species. 



3. B. ovatifolius. Baker. Branches woody, terete, glabrous, not 

 mottled. Petioles slender, glabrous, f— |- in. long, the rachis 1^-2 in. long;
