Abstract

The genus Salacia is an important element of the forest flora of the Western Ghats of Karnataka and is well known for its anti-diabetic properties. The region hosts a wide diversity with several taxa. The genus is considered as a taxonomically difficult one due to the complexity and diversity in floral characteristics. The species is still poorly understood with respect to its cytological characteristics. The present study explicates the diversity and distribution of Salacia species in the Western Ghats of Karnataka. Here, we also present the first report of the chromosome numbers of the species Salacia chinensis L. and Salacia oblonga Wall ex Wight and Ern Var. and is different from those of other previously reported Celastraceae genera. Conservation status of Salacia species of the Western Ghats of Karnataka has also been revised in this study. The diversity of floral morphology, leaf morphology, fruit and seed morphology, stem and root morphology were elaborated along with a dichotomous key to the Western Ghats species. Morphological study in S. chinensis L., S. malabarica Gamble, S. oblonga Wall ex Wight and Ern Var, S. macrosperma Wight, S. reticulata Wight and S. gambleana Whiting and Kaul is done for the first time using descriptor analysis. The paper describes 73 morphological traits that appear to be at least partly genetically controlled and can be used as descriptors of Salacia species.
