2. PYBAMIDOCARPTTS, Oliv. ; Benth. et Hook. f. 

 Gen. Plant, i. 798. 



Flowers hermaphrodite. Flower-tube very short ; sepals 3, imbri- 

 cate, orbicular, concave, leathery, passing' into the petals. Petals 

 7-10, of the same form as the sepals, gradually decreasing in size from 

 without inward, and passing into the stamens, the 3 or 4 innermost pro- 

 longed at the apex, erose. Stamens 20-30 in many rows, short, peri- 

 gynous ; anthers oblong ; connective flat. Ovary 3-gonous, pyramidal, 

 1-celled, 3-angled at the top ; stigma minute, 3-fid ; ovules very 

 numerous, affixed in many rows to three parietal placentae. Fruit 

 large, leathery, thick, cubical or pyramidal, thickened and bluntish 

 at the angles, carinated on the surfaces, 3-4-valved, few-seeded ; style 

 short. Seed large, oblong or roundish, angular ; testa crugtaceous, sur- 

 rounded by thin pulp ; albumen fleshy. Embryo. . . . — A small tree with 

 terete branches, annulate above the insertion of the leaves, which latter 

 are alternate, coriaceous, oblong, stalked ; leaf-stalks thickened at the 

 apex. Flowers small, in short axillary spikes ; fruit of the size of a 

 hazel-nut. 



The following is the only species described. 



1. P. Blackii, Oliv. ; Journ. Linn. Soc. ix. 171. 4 small tree 25 ft. 

 high, with glabrous cylindrical branches. Leaves alternate, stalked, 

 coriaceous, glabrous, oblong-elliptical, rounded at the base, cuspidate, 

 minutely denticulate, 6— 8 in. long, 2 \- 3J in. wide; stalk 5-9 lines 

 long, thickened at the apex ; stipules caducous. Flower-buds globular, 

 spherical, arranged in dense, axillary, shortly stalked spikes, J— 1 in.

The specimens in the herbarium have immature flowers only, hence there is nothing

3. BIVINIA, Tulasne ; Benth. et Hook. f. Gen. Plant, i. 800. 



Flowers hermaphrodite, monochlamydeous. Flower-tube very short. 

 Sepals 5-6 ovate, acute, valvate. • Stamens 40-60, emerging from 

 the base of the flower-tube, arranged in bundles alternating with 

 the sepals ; filaments thread-like ; anthers subglobose minute. Bisk 

 rather thick, lining the flower-tube and dividing at its throat into five 

 oblong-obtuse pilose lobes (staminodes) placed opposite to the sepals. 

 Ovary free or nearly so, oblong or subglobose, 3-lobed, 1-celled, with 

 numerous anatropal ovules attached to 4-6 parietal placentas ; styles 

 4-6 alternate with the placentas, persistent, ultimately cleft into two
