 Leaves usually opposite, leathery, with stipules. Flowers perfect, solitary 

 in the axils or in spikes, racemes, cymes or panicles. Caljrx with 3 or 4 

 valvate sepals. Petals as many as the sepals, 2-eleft or lacerate. Stamens 

 twice or four times as many as the petals, or rarely of the same number, 

 inserted at the base of a disk; filaments short or elongated; anthers 2- 

 eelled, opening lengthwise. Ovary inferior, or partly inferior, usually 

 3-5-celled or rarely 1-celled; styles united; stigmas sometimes lobed. 

 Ovules 2 or rarely 4 or more in each cavity, pendulous. Fruit leathery, 

 crowned with the calyx, indehiseent or tardily septicidal. The family con- 

 sists of about 15 genera, containing some 50 species, natives of tropical

1. EHIZdPHORA L. Sp. PI. 443. 1753. 



Evergreen trees, with an astringent bark, and stout pithy twigs. Leaves 

 opposite, entire; stipules elongated, interpetiolar, caducous. Flowers cream-

 to the base of the ovary, the 4 lobes leathery. Petals 4, emarginate, leathery. 

 Stamens 4—12, alternate with the petals; filaments short. Ovary 2-celled, half- 

 inferior, produced into a fleshy cone. Stigma 2-lobed. Ovules 2 in each 

 cavity. Fruit pendulous, 1-celled, leathery. Seed solitary, germinating in the 

 persistent fruit, the elongating radicle sometimes reaching the ground before
