Recognition, enumeration, and discussion of 21 species of lesser-sized Lobelias in South and South East Asia and Malesia are presented. A key to the lesser Lobelias, primarily based on seed shape and growth habit, is given. In Indochina and in the Malesian area the name Lobelia alsinoides Lam. is replaced by L. dopatrioides Kurz var. cantonensis (Danguy) W.J.de Wilde & Duyfjes. In the remaining area of L. alsinoides, mainly India, that species is divided into two varieties, viz. var. alsinoides and var. trigona (Roxb.) W.J.de Wilde & Duyfjes. Lobelia dioica R.Br. is a new record for Malesia. Lobelia reinwardtiana (C.Presl) A.DC. and Lobelia thorelii E.Wimm. are reinstated. Lobelia zeylanica L. var. walkeri C.B.Clarke is raised to species rank, L. walkeri (C.B.Clarke) W.J.de Wilde and Duyfjes. Lobelia reinwardtiana (C.Presl) A.DC. var. megalantha W.J.de Wilde & Duyfjes (India), L. dopatrioides Kurz var. kradungensis W.J.de Wilde & Duyfjes (Thailand), L. reptans W.J.de Wilde & Duyfjes (New Ireland), and L. serratifolia WJ.de Wilde & Duyfjes (Bougainville Isl.) are described as new.
