图1 隐性雌雄异株2种常见形态学性表达类型的花部特征。(A)以葛枣猕猴桃为例示性表达类型I (形态上雄花两性花异株); (B)以玉叶金花为例示性表达类型II (形态上两性花植株)。蓝色箭头和红色箭头所指分别为可育性器官和不育性器官。

Fig. 1 Floral traits of two common sex expression types of cryptic dioecious species. (A) Actinidia polygama, indicating sex expression type I (morphologically androdioecy). (B) Mussaenda pubescens, indicating sex expression type II (morphologically hermaphrodite). The blue and red arrows indicate fertile and sterile sex organ, respectively.
