Abstract

Senna spectabilis is an invasive alien species known for its extremely fast-growing habit, profusely flowering and fruit setting nature, and high coppicing ability. In India, its introduction is not well documented,which probably may have been introduced as an ornamental plant. Presently this species has aggressively spread across the moist deciduous forests of Wayanad wildlife sanctuary in the Western Ghats, peninsular India,with adverse impact on the survival of the indigenous species of flora and fauna. The present study used six distinct populations of the species, Anakkatty, Muthanga, Vythiri, Azhnjilam, Thiruvanathapuram and Munnar karyotype analysis. In mitotic metaphase, cells of S. spectabilis showed a stable chromosome count of 2n = 28, x =14. The statistical analysis shows that there was a significant difference between the characters studied. The observations were compared with the chromosome characters reported from native S. spectabilis population. While it was found that the chromosome number remainsthe same 2n = 28, there were differences with most of the characters studied. The study points to the requirement for more intense taxonomic studies and monitoring of this species and its populations.
