Sonerila Roxb. (Melastomataceae) is represented by 49 species and one variety in India, of which seven species are caulescent and tuberous, and endemic to the southern Western Ghats. The caulescent, tuberous species of the genus are revisited here based on field and herbarium studies. Sonerila kanjilasseriensis Arunraj, R.Reshma & Vishnupr. and S. keralensis Deepthikum. & Pandur. are reduced to synonymy of S. rheedei Wall. ex Wight & Arn. Since no type has so far been indicated for the genus, a lectotype is designated here. Detailed descriptions, illustration/photographic images and a key for the identification of the caulescent tuberous species in India are provided.
