摘要： Results on sporogenesis and gametogenesis in double-flowered Jasminum mesnyi showed that the development of anther wall follows the dicotyledonous type which is composed of epidermis, endothecium, middle layer and secretory tapetum. The cytokinesis of microspores follows the successive type. Microspores tetrads are tetragonal. Pollen grains are spheroidal, reticulate and tricolporate. The ovary that contains 2 ovules is anatropous, unitegmic and tenuinucellate on the axial placentation. Beneath the epidermis of the ovule, archesporial cells immediately turn to be the megaspore mother cells. Since the megaspore mother cells had dissolved, the megasporogenesis aborted. The horticultural interest and systematic significance of embryological features of double-flowered J. mesnyi is discussed.
