Hua He, Dunyan Tan, Xiaochen Yang

图2 具隐性雌雄异株性系统的分类群在被子植物中的系统分布。系统发育树参照APG IV (2016)和Li等(2019), 括号中数字表示具隐性雌雄异株性系统物种的属数。支长不代表真实时间尺度, 仅为美观考虑。♂表示雄花, ♀表示雌花, 表示两性花, 虚线表示该性别无功能, [ ]表示植株个体。

Fig. 2 The systematic distribution of taxa with cryptic dioecy species across angiosperm. Phylogenetic diagram adapted from APG IV (2016) and Li et al (2019). The value in parentheses represents the number of genera with cryptic dioecy species. Clade lengths are not indicative of true time scales and are for aesthetic purposes only. ♂ indicates male flowers, ♀ indicates female flowers, indicates hermaphrodite flowers, dashed line denotes a nonfunctional sex, [ ] indicates individuals.
