The tribe Plantagineae (Lamiales) is a group of plants with worldwide distribution, notorious for its complicated taxonomy, still unresolved natural history, and a trend of morphologic reduction and simplification. This tribe includes the plantains (Plantago), the small aquatic Littorella, and the northern Andean shrubs Aragoa. Some Plantago lineages exhibit remarkably high diversification rates, which further adds to the complicated classification, and the worldwide distribution of these plants raises numerous questions related to vicariance and dispersal. In this work, we present the broadest phylogeny of the group to date and discuss the evolutionary, morphological, and biogeographical implications of our phylogenetic results, including the description of two new species from the Americas.

如何绘制车前草：不同的车前草（系统）的系统发育

车前草族（拉美亚尔）是一组植物，分布在世界各地，以其复杂的分类学，仍未解决的自然历史以及形态减少和简化的趋势而臭名昭著。这个部落包括车前草（车前草），小型水生小岛和北部安第斯灌木Aragoa。车前草属的一些谱系显示出很高的多样化率，这进一步增加了分类的复杂性，这些植物在世界范围内的分布提出了许多与变异和分散有关的问题。在这项工作中，我们介绍了迄今为止最广泛的系统发育史，并讨论了系统发育结果的进化，形态和生物地理意义，包括对美洲两个新物种的描述。
