Abstract

Deroin T. & Sebsebe Demissew 2009. — The genus Seddera Hochst. (Convolvulaceae) inMadagascar. Adansonia, sér. 3, 31 (1): 207-214.

A new Malagasy species of Convolvulaceae, Seddera madagascariensis Deroin & Sebsebe, is described from the subarid bioclimatic region (Mahafaly and Androy). It has been confused for a long time with Evolvulus alsinoides (L.) L. due to its similar habit, it is clearly distinguished from the other endemic Malagasy species S. repens Hallier f., by its often asymmetrical leaf base, unilocular ovary included in the disk, as well as by its 1-seeded capsule. These unusual features in the genus Seddera are briefly discussed.
