Abstract: Microsporogenesis and male gametogenesis of Jatropha curcas L. (Euphorbiaceae) was studied in order to provide additional data on this poorly studied family. Male flowers of J. curcas have ten stamens, which each bear four microsporangia. The development of the anther wall is of the dicotyledonous type, and is composed of an epidermis, endothecium, middle layer(s) and glandular tapetum. The cytokinesis following meiosis is simultaneous, producing tetrahedral tetrads. Mature pollen grains are two-celled at anthesis, with a spindle shaped generative cell. A few abnormal microspores were observed following the early stages of microgametophyte development.
