A Contribution on the Anatomical Characters of Moringa oleifera Lamk. and their significance

Abstract

The anatomical structure of various organs of Moringa oleifera Lamk. has been investigated. Root is tetrarch. In old root large number of vessel elements embedded in xylem parenchyma cells are observed. In young stem 16 - 18 collateral vascular bundles are present in ring. Vascular cambium produces small amount of secondary phloem and large amount of secondary xylem. Eglandular trichomes are present on various parts of leaf. Stomata are anomocytic. A large semi - triangular collateral vascular bundle is the characteristic of midrib. Petiole is made up of central vascular cylinder and collenchyma containing oxalate crystals. Rachis has 10 - 12 collateral strands and tanniferous contents in cortical cells. Distinguishing characters have significance in pharmacognosy.
