title: Biosystematic studies on Enicostema axillare (Lam.) A. Raynal subsp. Axillare (Gentianaceae) in peninsular India.
abstract: The pantropical genus Enicostema (Gentianaceae) has three species and two sub species world over, namely, E. verticillatum (L.) Engl. (America), E. elizabethae Veldkamp (Madagascar) and E. axillare having 3 subsp. viz., subsp. axillare (Lam.) A. Raynal (India), subsp. latilobum (N.E. Br.) A. Raynal (East Africa) and subsp. littorale (Blume) A. Raynal (Indonesia). The present study aims to delimit the Indian taxa based on field and herbarium studies. Comparative morphology is studied using live as well as consulting wide range of specimens housed at various herbaria. The anatomy of leaf, stem, and root is studied using free hand sections and from epidermal peelings. The seed and pollen morphology are studied under SEM. Information on anatomy, palynology and seed micromorphology of E. axillare subsp. axillare is provided for the first time.
