摘　　要：珍珠莲为榕属攀援灌木 ,雌雄异株。雌花序中着生雌花 ,每个花序中平均有雌花310 4朵 ;雄花序中着生瘿花、雄花和两性花 ,每个花序平均有瘿花 391 0朵、雄花 10 4 8朵、两性花 2 0朵。自然状态下雌、瘿花的结实率和成虫瘿率分别为 95 88%、2 9 5 1%。雌、瘿花在生理上已完全分离。匍茎榕小蜂是唯一能进入花序产卵或传粉的共生昆虫 ,二者构成的传粉系统依靠形态结构的高度互适 ,物候生活史的相互吻合 。Ficus sarmentosa var. henryi is dioecious.In the female syconia exist average 310 4 female flowers while in the male syconia are average.391\^0 gall flowers,104\^8 male flowers and 2\^0 hermaphrodite flowers.Naturally, the production rate of the female flowers and the gall turning rate of the gall flowers are 95\^88% and 29\^51% respectively,and the female flowers and gall flowers are completely separeted physiologically. Wiebesia callida is the only mutualism insect that can enter the syconia to produce eggs and pollinate.And the pollnation system of the two depends on the suit each other quite well in their stucture,have a complete joint in their phenology and life cycle synchronism,and the specialization of their biological behaviors keep their obligatory and stability.
