摘要

基于对卷柏单孢菌群（包括S.effusa、S.microclada、S.monospora、S.subdaphana和S.submonospor）的广泛植物标本馆研究以及分子系统发育证据，发现了该群的另一个新种。采自滇东南大围山，故名卷柏。新物种与同类物种的明显区别在于其在主茎和枝条上的皮质和密叠瓦状腹面叶，长2.2-3.1毫米，宽1.1-1.5毫米，顶视基部扩大，茎和枝条强烈重叠，边缘具细齿；小孢子疣状和穿孔。对三个质体区域（rbcL、atpI、psbA）的系统发育分析表明，细孢S.subeffusa与近单孢S.submonospora聚在一起，嵌套在“S.microclada–S.effusa”分支和“S.monospor”分支之间。

Selaginella subeffusa, a new spikemoss from Southeast Yunnan, China

Based on extensive herbarium research of the Selaginella monospora group (incl. S. effusa, S. microclada, S. monospora, S. subdiaphana, and S. submonospora) and on molecular phylogenetic evidence, an additional new species to this group was discovered. It was collected from Dawei Mountain in southeast Yunnan, and here named as Selaginella subeffusa. The new species distinctly differs from similar species by its coriaceous and densely imbricate ventral leaves on main stems and branches, 2.2–3.1 mm long and 1.1–1.5 mm wide, with enlarged acroscopic base, and strongly overlapping stem and branches, and with denticulate margins; microspores verrucate and perforate. Phylogenetic analyses of three plastid regions (rbcL, atpI, psbA) showed that S. subeffusa clustered with S. submonospora and nested between the “S. microclada – S. effusa” clade and the “S. monospora” clade.
