 interior edge and each formed by an imilocnlar ovary tapering into 

 an apiculate style whose slightly dilated stigmatiferous apex often 

 adheres to the stigmas of the two other carpels. In the internal 

 angle of each ovary is seen a placenta supporting four ovules, 

 arranged in two vertical ascendent series, with the micropyle turned

downwards and outwards. There are flowers whose gynseceum is 

 formed of only two carpels. The fruit (fig. 337) is, accordingly, 

 composed of two or throe indej^endent, folliculiform, divergent, coria- 

 ceous carpels, each opening slowly inwardly to set at liberty from 

 one to four seeds. These (fig. 338) present beneath their double 

 coat, the exterior of which is fleshy and the interior crustaceous, a 

 fleshy albumen surrounding an embryo with inferior radicle and 

 large orbicular flattened cotyledons. In certain species of the same 

 genus, indicated under the name of Turpinia,'^ the carpels are inde- 

 pendent only in the upper portion and not towards the base. The peri- 

 carp, generally indéhiscent, is more or less thick, coriaceous or even 

 fleshy. In all the Triccros, however, the number of ovules is varia- 

 ble in each series, reduced even sometimes to one. There are ten 

 species ^ of this genus, arborescent or frutescent, growing in tem-
