  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. ( 4 ) in the series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed

    對數珠珊瑚的花器官發生和子房的發育過程進行了觀察.結果表明: （ 1 ）數珠珊瑚花被呈2 / 5螺旋狀發生，遠軸側的1枚先發生，其次為近軸側的1枚發生，最後側方的2枚花被幾乎同時發生，第3枚花被在靠近第1枚的位置發生，第2枚和第3枚之間有1個空隙; （ 2 ） 4枚雄蕊是同時發生的; （ 3 ）心皮發生於分生組織的遠軸側，心皮原基形成后，向上向軸生長，在子房成熟前在近軸側非正中位形成1個孔，該孔為心皮最終愈合前的殘跡，到子房成熟時，因子房的生長孔被擠壓縮小，在進一步的生長過程中愈合.子房由1枚心皮構成; （ 4 ）從子房發育過程的切片看，該植物的胚珠是在子房發生后不久發生的，子房上的圓孔形成時，從近軸側的分生組織發生胚珠原基，由胚珠原基分化出珠被與珠心
