Abstract:This article is a part of embryological studies of Basella rubra L. dealing with the microsporogenesis and megasporogenesis, and the deyelopment of male and female gametophytes. The results of observation are sumlnarized as follows:The formation of microspore was of simultaneous type and the microspore tetrads were arranged tetrahedrally. In the meiosis of PMCs, the changes in fornlation and disappearance of callose wall may be c1early seen. Pollen grain was 3-celled when shed, and formed six colpi (pancolpate) and reticulate sculpture on the pollen surface. The characters of glandular tapetum were appeared.
