. The natural history of plants. Botany. UMBELLIFEE^. 169 ramified clusters of cymes, with articulate pedicels. The calyx is gamosepalous, 4-5-dentate; the petals are triangular and valvate; and the unilocular and uniovulate ovary is surmounted by a thick style with umbilical summit and surrounded at the base by a large epigynous 10-lobed disk. The fruit is an elongate drupe the woody putamen of which has on one side an exterior furrow corresponding to a sort of vertical incomplete false partition, to which is applied the corresponding margin of the seed. On this side the albumen has a deep furrow and lodges, above, a small embryo with foliaceous cotyledons, but it is not ruminate like that oi Arthrophyllum. Pler'andra (fig. 221, 222) is exceptional in this family on another ground: the andrcecium is not isostemonous. It has a superior calyx, more or less developed, and five or more triangular and purandra {Nesopanax) vUiensu. valvate petals, more or less ad- herent, with a number of stamens many times that of the petals. In Plerandra proper the number of these stamens is indefinite and they are pluriseriate. The leaves are compound-digitate, and the ovary has 12 to 15 cells, surmounted by a stumpy and truncate style with little-pro- nounced StigmatiferOUS lobes. Fig. 221. Flower ©. In , which we can make only a section of the genus, the stamens are indefinite in number, simple or sometimes bifurcate; the ovary is 6-10-celled, with the styles united in a dentelate conical mass, and the leaves are compound-pinnate. In those named Balceria, with digitate leaves, we find some fifteen stamens, an ovary of only five cells and a style very flat with five indistinct lobes; in Triplasandra, from ten to eighteen stamens, five or six ovarian cells with as many petals, and compound-pinnate leaves; in Tuhidanthus, digitate leaves, five very adherent petals and a very great number of pluriseriate stamens and ovarian cells, with very small stigmatiferous lobes.
