The Crinum zeylanicum complex is divided into 3 species: C. zeylanicum (L.) L. s. str., C. kirkü Bak., and C. politifolium Wahlström sp. nov. The chromosome numbers found in East African material are 3n = 33, 2n = 22, and 2n = 30 respectively. Outside the region 2n = 22 is also found in C. zeylanicum. Each species has its own basic karyotype. TLC studies of alcaloid content revealed three different patterns. Synonymy, emended descriptions, ecological and phytogeographical data are given. A key to all Crinum species in East Africa is provided.
