ABSTRACT

In this paper studies on leaf venation characterized for four species of climbers namely, Clitoria ternatea Linn, Daemia extensa R. Br., Aristolochia bracteata Retz, and Gloriosa superba Linn. To morphotype leaves, these were sorted out on the basis of serrated versus entire margins, primary and secondary vein patterns, etc. With some exceptions, these characters are usually stable within morphotypes. The leaf size and shape are the least reliable characters in identifying leaves. After the leaves are sorted into these broad categories, one can further divide them by looking at higher order venation patterns and tooth type. This paper illustrated with line drawings of prepared stained leaves, provides a framework of the leaves. This study will be very useful to a broad range of people who work with plants.

Key words : Aristolochia, Climbers, Clitoria , Daemia, Gloriosa, Leaf venation.
