摘要
描述了葫芦科赤爬属植物生活史的主要过程以及胚胎学的重要特征，它们是：腺质绒毡层，胞质分裂同时型，小孢子四分体四面体型和等面体型，花粉粒散发时具两细胞，双珠被，厚珠心，寥型胚囊，珠孔端受精，胚胎发育柳叶菜型。
The main processes of life cycle of the genus Thladiantha were first investigated.Several important characters of embryology were observed and described as follows: secretory tapetum, simultaneous cytokinesis, microspore tetras, tetrahedral and isobilateral, two-celledpollen grains, bitegminous,crassinucellate, polygonad type embryo sac, micropylar fertilization,embryogenesis onagrad type.
