  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. ( 3 ) the carpellary primordium initiated from the abaxial side of flower primordium ; the carpellary primordium grew upwards and towards axis after it was formed, therefore an elliptic orifice was formed at the adaxial position of ovary, which was the remainder of the mouth of ovary before the ovary was fused completely. with the ovary maturing, the orifice was narrowed because of the ovary growth, at last fused completely. the gynoecium is composed of a single carpel.
