摘要

大多数被子植物(~94%)是同源的,只有少数被子植物将两种配子类型的产生分离到不同的生物个体上(雌雄异株)。然而,对于许多植物物种来说,生殖系统和习性并没有很好的记录。热带树木尤其如此,尽管它们很显眼,但人们对它们的了解却很少。Triplaris属的植物一直被描述为严格的雌雄异株。在使用解剖显微镜进行形态学分析后,我在这里展示了在Triplaris草药标本上观察到的一些完全形成的完美(雌雄同体)花。

Notes on the floral sexuality of some species of the tree genus Triplaris (Polygonaceae)
The majority of angiosperms (~94 %) are synoecious, with only a small minority separating the production of the two gamete types onto different biological individuals (dioecy). For many plant species, however, reproductive systems and habits are not well documented. This is particularly true of tropical trees, which, despite their conspicuity, are poorly understood. Plants in the genus Triplaris have been consistently described as strictly dioecious. After morphologic analysis using a dissecting microscope, here I present a number of fully-formed perfect (hermaphroditic) flowers observed on Triplaris herbaria specimens.
