Abstract
Members of family Cucurbitaceae possess either simple or branched tendrils that occupy lateral position with respect to other organs in the axil of the leaf. The transverse section of tendril shows five ridges alternating with five furrows. The distribution of tissues is same in all species. The vascular bundles are bicollateral. The vascular supply to the tendril suggested some relationship between the axillary flower and tendril and can be regarded as a modified first lateral branch of the floral axis. The similarity in the anatomy of the basal part of the flower and that of the tendril imply support this conclusion.
