抽象的。卷柏属(Selaginellaceae)植物大多对干燥敏感，少数物种能抵抗极度干燥，恢复代谢功能，并在复水后快速生长。然而，关于卷柏属复活物种的解剖特征的信息有限。在本研究中，我们比较了两个复活物种(S.Pulvinata和S.sanguinolenta)和两个非复活物种(S.kraussiana和S.chryocaulos)的小叶微形态和超微结构。与非复活种相比，复活种气孔主要分布在紧贴茎的小叶近轴面，小叶小而厚，气孔大小较小，气孔密度较高，表皮细胞壁较厚，叶绿体较多，细胞质较致密。这两个复活物种的这些显微形态和超微结构特征有利于减少蒸腾和脱水伤害，可以认为是对干旱环境的生态适应。
Abstract. Most species in the genus Selaginella (Selaginellaceae) are susceptible to desiccation, while a few species are able to withstand the extreme desiccation, recover metabolic functioning, and grow rapidly after rehydration. However, there is limited information about the anatomical features of the resurrection species in Selaginella. In the present study, we compared the microphyll micromorphology and ultrastructure of two resurrection species (S. pulvinata and S. sanguinolenta), and two non-resurrection species (S. kraussiana and S. chrysocaulos). Compared with the two non-resurrection species, the two resurrection species had most of their stomata distributed on the adaxial surface of microphylls that were tightly attached to stems, and possessed smaller and thicker microphylls, smaller stomatal size, higher stomatal density, thicker epidermal cell walls, more chloroplasts, and denser cytoplasm. These micromorphological and ultrastructural features of the two resurrection species were beneficial in reducing the transpiration and dehydration damage and could be considered as ecological adaptations to xeric environments.
