Abstract
The genus Secamone R.Br. is placed in subfamily Secamonoideae of Apocynaceae. This subfamily is characterized by having four pollinia in each pollinarium, not two as in subfamily Asclepiadoideae, neither a spate-like translator as in Periplocoideae, the two phylogenetically most closely related taxa. Secamone is a palaeotropic genus of suffrutescent twiners or small scrambling herbs, rarely erect shrubs, with usually small white to yellow flowers. In a series of publications, KLACKENBERG (1992, 1997, 1998, 2000a, 2000b, 2000c, 2002) has recognized 65 species in Madagascar. Among herbarium material sent to me recently from Geneva and collected during a continuous inventory work conducted in Madagascar by Swiss botanists in collaboration with Malagasy staff, now one more specimen has proved to represent a new species, Secamone galinae, which is here described and illustrated.
