A cyto taxonomic study of some members of the tribe ocimoideae labiatae

A cyto taxonomic study of some members of the tribe ocimoideae labiatae

Revue Roumaine de Biologie 23(1): 3-10

A detailed karyological analysis of 15 taxa belonging to 6 genera of the tribe Ocimoideae under Labiatae [Ocimum americanum (2 strains), O. gratissimum, O. sanctum (2 strains) Moschosma polystachyum, Orthosiphon rubicundus, Plectranthus coetsa (2 strains), P. sp., P. gerardianus, P. glaucocalyx, P. purpuratus, Hyptis suaveolens and Lavandula burmanni] was carried out to get a comprehensive idea about the karyosystematic relationship and the mechanism of speciation among the members of the tribe. Several chromosome numbers exist within the tribe. But in spite of the difference in chromosome numbers, there exists a relationship between the different genera and species as evidenced by their karyotypes and frequent occurrence of intraspecific or interspecific variations. Different degrees of polyploidy and structural alteration of chromosomes are found prevalently in this tribe. Their role in the mechanism of speciation is obvious. The 2 subtribes have distinct prevalent chromosome numbers and their inclusion into 2 separate subtribes is justified on this basis.
