Abstract

, a new species of Cyperaceae (CarexsectionRhomboidales) from the limestone landform in northern Guangdong, China is described and illustrated. The new species is similar to C. B. Clarke, but differs in having shorter culms (10-15 cm vs 20-55 cm) and spikes (1-1.5 cm vs 3.7-7 cm), leaves wider (15-20-35 mm vs 5-10 mm) and lighter colored (pale green or yellow-green vs dark green), nutlet beak oblique (vs erect or slightly curved), and slightly thickened (vs thickened) style base. Following the IUCN Red List Criteria (IUCN 2024), is assessed as 'Data Deficient (DD)'.

摘要

本文描述并图示了中国广东北部石灰岩地貌莎草科(菱形苔草组)的一个新物种。该新物种与C. B. Clarke相似,但不同之处在于其秆较短(10 - 15厘米对20 - 55厘米)、穗较短(1 - 1.5厘米对3.7 - 7厘米)、叶较宽(15 - 20 - 35毫米对5 - 10毫米)且颜色较浅(淡绿色或黄绿色对深绿色)、小坚果喙倾斜(对直立或稍弯曲)以及花柱基部稍增厚(对增厚)。依据世界自然保护联盟红色名录标准(IUCN 2024),该物种被评估为“数据缺乏(DD)”。
