A MICROMORPHOLOGICAL STUDY FOR THE GENERIC DELIMITATION OF INULA L. (S.STR.) AND ITS ALLIED GENERA (INULEAE-COMPOSITAE) FROM PAKISTAN AND KASHMIR

RUBINA ABID AND M. QAISER

Abstract: Micromorphological characters viz., receptacular surface and anther apices strengthen the existence of 22 taxa of Inula L., (s.str.) and its allied genera (Pentanema Cass., Duhaldea DC., Drittichia Greuter and Iphiona Cass.) from Pakistan and Kashmir. The receptacles are without scaly ridges in the genera Inula L. (s.str.) and Pentanema, while the genera Duhaldea, Dittrichia and Iphiona have unevenly incised scaly ridges on receptacle. Acute-obtuse anther apices are present in Inula, Pentanema, Dittrichia and Iphiona. The genus Duhaldea is characterized by the presence of truncate-emarginate anther apices.
