The petals are imbricated or contorted, and the rest of the flower is similar to that of Jatropha, Sarcoclmium, Galearia. Only one species is known, a Brazilian tree, with compound digitate leaves and flowers disposed in compound cymes. Jleurites AlmHte.[E-meoc0e,)vevmeiJlm. ^-^^^ BanCOuKer), COmpOSed of trees from the warm regions of Asia and Oceania, has simple leaves digitinerved at the base and more or less cut. The flowers, fruits, and seeds (fig. 170, 171) are similar to those of the preceding genera, but the valvate calyx is irregularly divided into a variable number of straps, and the stamens, instead of being indefinite in number, are united in large quantities upon a common elongated receptacle. Saffofia, consisting of trees with simple leaves from Guiana, has also numerous stamens at the centre of the male flower. The sepals and petals are imbricated and the male flowers have five altemir petalous glands which are wanting in the female flowers. Ghceto- carpus^ composed of eastern India and tropical America, has also simple leaves. The tetramerous flowers have an imbricated calyx but no corolla, and from eight to sixteen stamens; they may thus be considered as a quarternary floral apetalous type of Jatropha or Sagotia. Eevea constitutes a small sub-series in this group. The moncer cious flowers are apetalous, and the gamosepalous calyx has long valvate or subinduplicate divisions. The introrse anthers, collected in one or two verticils, are applied vertically to the surface of a central erect cylindrical column, surmounted by a small terminal body. The ovary is surmounted by a column-shaped style. It consists of trees with alternate digitate trifolioliate leaves and monce- cious flowers united
