Taxonomic revision of Ceropegia (Apocynaceae: Ceropegieae) in India

Abstract

The genus Ceropegia (Apocynaceae: Ceropegieae) is revised for India based on field observation, literature survey and extensive herbarium studies. Sixty one taxa are recognized under seven sections. Nomenclatural anomalies are resolved. Distribution status is given for each species. A lectotype is designated for C. schumanniana and second step lectotypes are designated for C. hookeri and C. lucida; C. karulensis is reduced here as a variety of C. sahyadrica; C. mizoramensis and C. murlensis are reduced to the synonymy of C.
longifolia subsp. sinensis. Detailed descriptions, notes, colour photoplates and taxonomic keys for sections, species and infra-specific taxa are presented.
