. The natural history of plants. Botany. 486 NATURAL EISTOBY OF PLANTS. Aexioxicon five stamens' alternating with these latter leaves, each consisting of a thick incurved filament and an introrse two-celled basifixed anther of longitudinal dehiscence. Alternating with these stamens are five pairs of thick glands, the glands of each pair approximated' to form a crescent with its concavity outwards ; they sur- round a little depression which lodges a short abortive gynseceum. In the female flowets the perianth is nearly the same as in the males, except that the number of its leaves is more variable. The stamens and the glands accom- panying them are arranged as in the male flower, but the former are sterile, having no anther, or only a rudiment at the top of the filament. The gynseceum here consists of a free ovary, covered with peltate scales and sur- mounted by a narrow style, at first inflexed, and divided above into two little stigmatiferous lobes. In the ovary-cell is seen a parietal placenta, bearing nearly at its top two collateral descending ana- tropous ovules,' whose micropyles, capped by their obturators,^ turn up under the hilum towards the placenta (fig. 297). The fruit is a naked drupe, but its mesocarp is not thick. The seed-coats enclose a fleshy albumen and an embryo with foliaceous cotyledons and a cylindrical superior radicle. Only one species of this genus is known,* a Chilian tree, with alternate opposite or subverticiUate leaves, simple entire petiolate and exstipulate, and covered like most of the organs with scurfy peltate hairs, The flowers form racemes, simple or more rarely ramified, and solitary or few together in the axils of the leaves.
