  1. In this paper the floral ontogeny and the ovary development of rivina humilis l. were observed. the results showed that ( 1 ) the tepal primordia initiated in 2 / 5 spirals. the abaxial one initiated first, then the adaxial one, finally the lateral two initiated nearly simultaneously. the third one initiated on the position near the first tepal, and there is a gap between itself and the second tepal. ( 2 ) the 4 stamineal primordia initiated in one whorl at the same time.
