Scientific Name:Ipomoea aegyptia L.
Description:Species Description - Characterized by leaves completely divided into 5, untoothed and unlobed segments, or leaflets, and rather large, white flowers, this twining vine is frequent on thickets, on hillsides and in fields at lower altitudes, in moist and dry parts of Porto Rico, growing also on Mona and Vieques islands, and occasionally planted for ornament. It has very wide distribution in tropical regions, both in the New World and the Old. It is not known where the species originated; we regard it as indigenous in Porto Rico, but this may be open to question; we have not observed it above about 150 meters elevation. For description of the genus we refer to our account of Ipomoea polyanthes. Ipomoea aegyptia (originally recorded as from Egypt) is a long-hairy vine, from 2 to 4 meters long, or longer. Its long-stalked leaves are pedately compound, being divided into 5, thin, unstalked, elliptic to lance-shaped segments from 3 to 9 centimeters long, which are long-pointed, and narrowed to the base. The flowers are few together on stalks usually longer than the leaf-stalks, the individual ones on slender stalks from 1 to 5 centimeters long; the thin, unequal, ovate to oblong sepals are long-hairy, the outer ones 2 or 2.5 centimeters long; the white corolla is about 3 centimeters long, the ovary 4-celled. The globose capsule is about 15 millimeters in diameter, the seeds smooth.
