【 摘 要 】

This study analyzed the morphology and anatomy of the Cordia trichotoma (Vell.) Arrab. ex I. M. Johnst diaspore. The objectives were: the structural analysis of the calyx and corolla that persisted in the ripe fruit and acted in the anemocoric dispersion process; the vascularization of the gynoecium for better understanding of the carpel/locule number of the ovary; nectary structure; and the anatomical analysis of the developmental pericarp and seed for better definition of the fruit type. The results showed that the perianth had aerenchyma and the ovary was 2- 4- locule forming endothelium and false septum. The fruit was drupoid nuculanium and the seed was exotestal.
