Abstract

Callmander, M. W., I. Luino, S. Da-Giau, C. Rakotovao & L. Gautier (2014). A synoptic revision of the Malagasy endemic genus Socratina Balle (Loranthaceae). Candollea 69: 65–73. In English, English and French abstracts.The hemiparasitic endemic genus Socratina Balle (Loranthaceae) is revised for Madagascar. Three species are recognized, including a new one, Socratina phillipsoniana Callm. & Luino. The vegetative and floral morphology of the new species is distinctive; in particular the conspicuous longitudinal villous fringe of long dendritic trichomes on the outer surface of its corolla along each suture of the lobes that contrasts with the shorter floccose indument that covers the rest of the outer corolla surface. All three known species are provided with preliminary risk assessments based on the IUCN Red List Categories and Criteria. A key to the genus is presented and a discussion of the morphological affinities of each species is also provided.
