Calyx campanulate, with a short tube ; segments in two distinct 

 rows, usually 8, sometimes 10. Corolla campanulate, as long as the 

 calyx, with the same number of segments, which are entire, oblong and 

 much imbricated. Stamens inserted opposite the segments of the 

 corolla at their base ; filaments subulate, glabrous ; anthers oblong- 

 lanceolate ; staminodes one between each filament, large, oblong, peta- 

 loid, fimbriate. Ovary globose, silky, 8-10-celled ; style long, subulate. 

 Berry ellipsoid, with a thin firm pericarp. Seed usually by abortion 

 solitary, exalbuminous, with very thick amygdaloid cotyledons and a 

 short radicle. — Erect trees, with copious milky juice, stipulate petioled 

 entire' coriaceous leaves usually crowded at the end of the branchlets 

 and flowers in dense umbels from the end of the branchlets, with the 

 leaves.

1. B. Parkii, Kotschy in PI. EnoU. t. 2. A tree reaching a 

 height of 30-40 ft., with a trunk 5-G ft. in diameter branching like an 

 oak, and yielding copious milky juice, which coagulates into a kind of 

 caoutchouc. Leaves usually crowded at the tips of stout rugose 

 glabrous branchlets, petioled, stipulate ; petiole 2-3 in. long, glabres- 

 cent, pubescent at first ; stipules lanceolate, subpersistent, about ^ in. 

 long, silky on the back ; blade oblanceolate-oblong, 6-9 in. long, 3-4 

 in. broad, broadly cuneate or rounded at the base, subcoriaceous, 

 glabrous when mature on the upper surface, thinly pubescent beneath, 

 furnished with 20-25 pairs of prominent erecto-patent main veins. 

 Flowers in dense umbels from the axils of the leaves at the end of the 

 branchlets ; pedicels J-1 in. or more long, thinly clothed when young 

 with ferruginous tomentum. Calyx campanulate, coriaceous, with a 

 short tube and usually 8 oblong-lanceolate segments, the outer 4 

 especially densely coated with ferruginous tomentum. Corolla as long 

 as the calyx, with a short tube and oblong glabrous imbricated seg- 

 ments. Stamens as long as the corolla-segments ; anthers oblong- 

 lanceolate, ^ in. long, half as long as the subulate glabrous filaments. 

 Staminodes oblong-cuspidate, shorter than the stamens. Ovary globose, 

 silky ; style slender, variable in length, sometimes protruded from the 

 corolla, sometimes included. Fruit ellipsoid, 1^-2 in. long, with a 

 thin pericarp and usually a single seed, with very thick cotyledons. —
