摘要
本报告描述了 Selliguea quinquefida（多瓣荠属），它是产自中国广西的一个钙质新种，并附有插图。该新种是该属中第二个叶片为单叶和掌状叶的物种，其独特之处在于叶片为单叶，基部呈心形。它生长在一个特殊的栖息地，根茎深深匍匐在相对干燥的石灰岩上硬化的白垩质土壤中，叶片发育完全时总是呈掌状五裂，形状为五角形。本文讨论了 S. quinquefida 与该属中所有其他具有掌状叶片的物种之间的差异和栖息地。
Selliguea quinquefida (Polypodiaceae), a new calciphilous species from a karst area in Guangxi, China
Selliguea quinquefida (Polypodiaceae), a new calciphilous species from Guangxi, China, is described and illustrated. The new species is the second within the genus with simple and palmate fronds and unique in having simple laminae with cordiform bases. It grows in a peculiar habitat with its rhizome creeping deeply within hardened chalky soils on limestone under relatively dry conditions and always bears palmately 5-lobed fronds with pentagonal shape when fully developed. The differences and habitats among S. quinquefida and all other species with palmate fronds in the genus are discussed.
