A hallmark of flowering plants is their ability to invade some of the most extreme and dynamic habitats, including cold and dry biomes, to a far greater extent than other land plants. Recent work has provided insight to the phylogenetic distribution and evolutionary mechanisms which have enabled this success, yet needed is a synthesis of evolutionary perspectives with plant physiological traits, morphology, and genomic diversity. Linking these disparate components will not only lead to better understand the evolutionary parallelism and diversification of plants with these two strategies, but also to provide the framework needed for directing future research. We summarize the primary physiological and structural traits involved in response to cold‐ and drought stress, outline the phylogenetic distribution of these adaptations, and describe the recurring association of these changes with rapid diversification events that occurred in multiple lineages over the past 15 million years. Across these threefold facets of dry‐cold correlation (traits, phylogeny, and time) we stress the contrast between (a) the amazing diversity of solutions flowering plants have developed in the face of extreme environments and (b) a broad correlation between cold and dry adaptations that in some cases may hint at deep common origins.

边缘的被子植物：肢体，多样性和系统发育。

开花植物的标志是它们能够入侵某些最极端和最动态的栖息地，包括寒冷和干燥的生物群落，其能力远大于其他陆地植物。最近的工作为系统发育分布和进化机制提供了见识，这些机制和机制使这一成功得以实现，但需要综合具有植物生理特性，形态和基因组多样性的进化观点。将这些不同的组成部分联系起来，不仅可以通过这两种策略更好地理解植物的进化平行性和多样性，而且还提供了指导未来研究所需的框架。我们总结了应对寒冷和干旱胁迫的主要生理和结构特征，概述了这些适应的系统发育分布，并描述了这些变化与过去1500万年来在多个谱系中发生的快速多样化事件的反复关联。在干冷相关性的这三个方面（特征，系统发育和时间）上，我们强调了以下两者之间的对比：（a）面对极端环境，开花植物产生了惊人的溶液多样性；（b）低温与低温之间的广泛相关性某些情况下可能会暗示深层的共同起源。
