Abstract

We conducted a comparative micromorphological study on the leaves of all nine genera of the Rosaceae tribe Spiraeeae, including the monotypic Korean genus Pentactina. Spiraeeae possess amphistomatic and hypostomatic leaves. Leaf epidermal characteristics varied with the morphology of stomatal complexes, epidermal cells, trichomes, and epicuticular waxes. Specific leaf epidermal features may be systematically relevant for identifying lower taxonomic levels, genera, and/or species. For example, papillate epidermal cell types were consistently observed in Spiraea sect. Calospira. Hirtellous trichomes are diagnostic characteristics of the genera Holodiscus and Kelseya among this tribe. Short-stalked capitate glandular and crispate villous trichomes were only observed in Holodiscus microphyllus and Spiraea douglasii, respectively. We also confirmed that leaf epidermal characteristics strongly support the independent taxonomic position of the Korean endemic Pentactina and the transfer from Physocarpus to Spiraea of Physocarpus insularis. Moreover, we identified xeromorphic features in the studied taxa and inferred their ecological functions, such as water repellence and anti-transpirant activities. This study presents new perspectives for future research on character evolution and xeromorphic adaptation on the basis of leaf epidermal characteristics.

蔷薇科 Spiraeeae(杏仁亚科)的叶片微形态及其系统学和生态学意义
我们对蔷薇科 Spiraeeae 属的所有九个属(包括单型的韩国 Pentactina 属)的叶片进行了微形态比较研究。Spiraeeae 有两性叶和半两性叶。叶表皮特征因气孔复合体、表皮细胞、毛状体和表皮蜡的形态而异。特定的叶片表皮特征可能与识别较低分类级别、属和/或种有关。例如,在 Spiraea sect.Calospira。具微糙硬毛是该族中 Holodiscus 属和 Kelseya 属的诊断特征。只有在 Holodiscus microphyllus 和 Spiraea douglasii 中分别观察到短柄头状腺毛和脆状长柔毛。我们还证实,叶表皮特征有力地支持了韩国特有的 Pentactina 的独立分类地位,以及 Physocarpus insularis 从 Physocarpus 到 Spiraea 的转移。此外,我们还发现了所研究类群的异形特征,并推断出它们的生态功能,如拒水和防汗活性。本研究为今后基于叶表皮特征的特征进化和异形适应研究提供了新的视角。

期刊介绍: The Botanical Journal of the Linnean Society publishes original papers on systematic and evolutionary botany and comparative studies of both living and fossil plants. Review papers are also welcomed which integrate fields such as cytology, morphogenesis, palynology and phytochemistry into a taxonomic framework. The Journal will only publish new taxa in exceptional circumstances or as part of larger monographic or phylogenetic revisions.
