Abstract

• Morphological and anatomical characteristics of Coccinia grandis (L.) Voigt. and Cucumis trigonus Roxb. belonging to the family Cucurbitaceae were studied at Department of Botany, University of Mandalay. The specimens were collected from Chanmyathazi and Ngazun Townships of Mandalay Region from June to October, 2017. The morphological characteristics of the two species were annual, climbing or creeping herbs. Leaves were simple, alternate and exstipulate. Inflorescences were axillary or solitary cymes with unisexual, actinomorphic and epigynous flowers. In the anatomical characteristics, the anomocytic types of stomata present on both surfaces of laminae of the two species. The vascular bundles of the two species were bicollateral type in petioles, midribs and stems. The vascular bundles of the roots were radial type, and tetrarch in Coccinia grandis (L.) Voigt., and polyarchin Cucumis trigonus Roxb. The morphological and anatomical characteristics of the two species are useful in identification of the plant.
