. The natural history of plants. Botany. 26 NATURAL mSTOBY OF PLANTS. lEntada polystachya. seeds suspended on fleshy funicles. X dolabriformis,^ the only species of this genus, is a lofty unarmed tree, from tropical Asia. Its leaves are bipinnate, with a few broad leaflets possessing petiolary glands. Entada^ too, possesses the flowers of Adenanthera, Elephantorrhiza, &c. The receptacle forms a shallow cup lined by a glandular disk, external to which are inserted the stamens. The petals are free, but their edges often stick together for some way up from the base. The gynseceum is sessile or nearly so. Hence, to find characters peculiar to the genus we must turn our attention elsewhere. In the fruit alone will such be found. It forms a flattened pod, straight or curved edgewise, as the pericarp is thin or thick and woody. At maturity the marginal sutures persist (fig. 20), while the valves separate into as many joints as there are seeds. The lines of demarcation are transverse and very sharp; and at each line the two walls of the endocarp touch, the pericarp forming as many rectangular segments, usually transversely elongated and persisting around the seeds,, which they envelope completely. Each seed contains within its coriaceous coats a large exalbuminous embryo- JEntada consists of ten or twelve species^ of tropical plants, of which one-third belong to Africa and another to America; while one species, E. scandens, Benth.,* is naturalized on the coasts of all warm countries. The genus consists of shrubs, often climbing and holding on by tendrils repre- senting the terminal leaflets of their bipinnate leaves; these are not glandular, and possess two lateral stipules. The flowers, herma- phrodite or polygamous, form slender spikes, terminal or axillary, solitary or geminate, or even collected at the ends of the branches.
