异质体在海洋岛屿上被认为是罕见的。异种风格在海洋岛屿上真的很罕见吗？是什么让异质风格在这些岛屿上变得罕见？为了回答这些问题，我们对海洋岛屿上的异种生殖研究进行了综述。总的来说，在海洋岛屿上进行的异种繁殖研究并不多。从异型花柱向其他性系统的转变也可能导致异型花柱的罕见，以及异型花柱物种在海洋岛屿上的定殖/本土进化的困难。进一步研究海岛上异花柱属精神病属植物的生殖系统，将为海岛植物生殖研究提供新的思路。
Heterostyly has been considered rare on oceanic islands. Is heterostyly truly rare on oceanic islands? What makes heterostyly rare on such islands? To answer these questions, we review the reproductive studies of heterostyly on oceanic islands. Overall, not many reproductive studies of heterostyly have been performed on oceanic islands. Shift from heterostyly to other sexual systems may also contribute to rarity of heterostyly, in addition to difficulty of colonization/autochthonous evolution of heterostylous species on oceanic islands. Further investigation of reproductive systems of the heterostylous genus Psychotria on oceanic islands would provide new insights on plant reproduction on oceanic islands.
