M. QAISER AND RUBINA ABID
Abstract
Distribution pattern and ecology of 22 taxa belonging to Inula L. (s.str.) and its allied genera viz., Pentanema Cass., Duhaldea DC., Dittrichia Greuter and Iphiona Cass., has been analyzed from Pakistan and Kashmir. Five species of Inula and 2 species of Pentanema are typically Irano-Turanian element, P. indicum is Indian element, both the species of Iphiona are Saharo-Sindian elements, while Inula racemosa and 3 species of Duhaldea are Sino-Japanese elements. I. acuminata and I. obtusifolia are distributed in transitional zone between Irano-Turanian and Sino-Japanese regions. Three species of Inula are classified as biregional elements, from which I. clarkei and I. orientalis equally distributed in Irano Turanian and Sino-Japanese regions, whereas I. britannica is distributed in Euro-Siberian and Irano-Turanian regions. P. divaricatum and P. vestitum are also biregional elements, former species found in Saharo-Sindian and Irano-Turanian regions and latter species extends to Saharo-Sindian and Indian region. However, Dittrichia graveolens is also considered as a biregional element distributed in Irano-Turanian and Mediterranian regions.
