7.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 .
