Abstract
The petiolar anatomy of sixteen species belonging to fourteen genera of Bignoniaceae has been studied. Two aspects, namely, the vascular pattern in the slender part of the petiole and the mode of vascular supply from the primary rachis to leaflets or secondary rachii, are taken into consideration. On the basis of the vasculature as seen in transection of the slender part, four main types of petioles have been recognised, while there are three patterns of vascular supply. A key also has been devised to identify these sixteen species.
