巴戟天湖（Rubiaceae）是一个大属，包括80多个物种，是乔木、灌木或木本攀缘植物，主要分布于旧大陆热带和亚热带（Peterson 1990，Johansson 1994，Mabberley 2008）。在所检查的巴戟天物种中，已报告了广泛的有性系统，包括单形两性体、双足两性体、雌雄异株和雌雄异株（Philip and Mathew 1978，Reddy and Bahadur 1978，Johansson 1994，Puff et al. 2005，Nishide et al. 2009，Sugawara et al. 2010）。然而，大多数巴戟天物种的性系统仍然不清楚。巴戟天f.根据权利要求1，其是分布于中国西南部（云南）至越南和印度北方的巴戟天属的一种，被认为是单态的（Ruan 1999，Chen 2003）。然而，在我们的初步调查中，该物种似乎是二型的，具有二型的性质和功能雌雄异株。异花柱植物的形态特征是具有两种不同花型的植物：长花柱和短花柱（达尔文1877，巴雷特和理查兹1990，巴雷特1992）。在一些二分生的属中（例如，Cordia、玉蜀黍属、玉叶金花属、菜属、九节属、肉果藤属等），据报道，distyly已经进化成diopyryl（Opler等，1975，Bawa 1980，海滩和Bawa 1980，Barrett和理查兹1990，Webb 1999），并且在Diopyryl中衍生自巴戟天villosa Hook的Distyly。F.缅甸克钦邦Hukaung山谷的茜草
Morinda L. (Rubiaceae), a large genus comprising more than 80 species, is trees, shrubs, or woody climbers, and mainly distributed in the Old World tropics and subtropics (Peterson 1990, Johansson 1994, Mabberley 2008). Among the species examined of Morinda, a wide range of sexual systems, including monomorphic hermaphrodite, distylous hermaphrodite, dioecy, and androdioecy, has been reported (Philip and Mathew 1978, Reddy and Bahadur 1978, Johansson 1994, Puff et al. 2005, Nishide et al. 2009, Sugawara et al. 2010). However, the sexual system in most of the Morinda species still remains unclear. Morinda villosa Hook. f., which is one of the Morinda species distributed from southwestern China (Yunnan) to Vietnam and northern India, has been regarded as monomorphic in floral morphology (Ruan 1999, Chen 2003). In our preliminary investigations, however, the species appeared to be dimorphic with a distylous nature and functionally dioecious. Distylous species are morphologically characterized by having two types of plants that bear different flower morphs: longand short-styled morphs (Darwin 1877, Barrett and Richards 1990, Barrett 1992). In some distylous genera (e.g., Cordia, Coussarea, Mussaenda, Nymphoides, Psychotria, Sarcotheca, etc.), it is reported that distyly has evolved into dioecy (Opler et al. 1975, Bawa 1980, Beach and Bawa 1980, Barrett and Richards 1990, Webb 1999), and in Dioecy Derived from Distyly in Morinda villosa Hook. f.
