研究进展：本文首次报道了新热带区的胎生现象，并讨论了具有胎生特征的三个谱系之间的进化关系。 方法：观测数据是在实地考察和植物标本收集过程中收集的。 然后将这些数据绘制到先前研究中为Mexiataceae开发的系统发育上。结果：胎生现象在凤尾兰科三族三属六种植物中均有报道。 这些物种具有趋同的特征，如草本习性和蒴果，并栖息在阴凉的热带雨林地板相似的生态位。结论：这一记录的会聚胎生分布在不同的谱系中，可以引发讨论的作用，在人口中的个人分布的现象，以及有助于在开花植物胎生的知识。
Premise of research. We present here the first reports of vivipary in Neotropical Melastomataceae and remark on the evolutionary relationships among the three lineages that share this feature. Methodology. The observational data were gathered during field expeditions and from herbaria collections. These data were then plotted onto a phylogeny developed for the Melastomataceae in a previous study. Pivotal results. Vivipary is reported in six species belonging to three genera and three tribes of Melastomataceae. These species have convergent characters, such as an herbaceous habit and capsular fruits, and inhabit similar ecological niches in shaded tropical rain forest floors. Conclusions. This record of convergent vivipary distributed among different lineages could elicit discussions regarding the role of the phenomenon in the distribution of individuals within populations as well as contribute to the knowledge of vivipary in flowering plants.
