2. PYRAMIDOCARPUS, 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, 
l-celled, 3-angled at the top; stigma minute, 3-fid; ovules very 
humerous, affixed in many rows to three parietal placente. 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 crustaceous, 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.

Flowers hermaphrodite, monochlamydeous. Flower-tube very short. 
epals 5-6 ovate, acute, valvate. Stamens 40—60, emerging from 
the base of the fower-tube, arranged in bundles alternating with 
the sepals ; filaments thread-like; anthers subglobose minute. Disk 
rather thick, lining the flower-tube and dividing at its throat into five 
oblong-obtuse pilose lobes (staminodes) placed opposite to the sepals.
