- Taxonomy of six species of Chlorophytum (Liliaceae) from India has been reassessed in the light of their morphological and cytological characters. C. tuberosum (Roxb.) Baker (2n= 16), a wide-spread species, is morphologically well defined but C. bharuchae Ansari, Raghavan & Hemadri (2n= 16) has been confused with C. glaucum Dalz. and C. glaucoides Blatter (both 2n= 42) by earlier workers. C. malabaricum Baker (2n= 42) is a delicate species and occurs in the Nilgiris and the Western ghats. Two closely allied species, C. nepalense (Lindley) Baker and C. khasianum Hooker fil. (both 2n= 56) are distributed in Eastern India. The first two species, with 2n= 16, have been considered as at the diploid level with base number 8 while the rest of them appear to be autoallopolyploids with base number 7.
