Abstract: Carex bambusetorum Merr., a perennial herb of Cyperaceae, is endemic to Guangdong Province. Ever since the type specimen of C. bambusetorum was collected by Elmer Drew Merrill in 1917, no subsequent records of this species have been made. Due to the limited knowledge of this species, nomenclatural confusion persists in the application of this name and C. planiscapa Chun & F. C. How, which urgently needs clarification. Recently, this species was rediscovered at its type locality, Luofu Mountain. Based on field observations and newly collected specimens, we revised and supplemented the morphological description of C. bambusetorum, discussed its morphological variation, corrected the misapplication of C. bambusetorum and C. planiscapa, confirmed that C. bambusetorum belongs to C. sect. Lageniformes (Ohwi) Nelmes, and updated the key to C. bambusetorum and the species similar to it.

摘要: 罗浮山薹草Carex bambusetorum Merr.是一种莎草科薹草属的多年生草本植物,是广东省特有植物。该种自1917年Elmer Drew Merrill采集模式标本之后,就再未被采集记录过。因对本种知之甚少,本种长期存在与扁茎薹草C. planiscapa Chun & F. C. How名称误用的情况。最近该种在模式产地罗浮山再次被发现,根据野外观察和新采集的标本,本文对罗浮山薹草的形态描述进行补充修订,讨论其性状变异情况,更正罗浮山薹草与扁茎薹草的名称误用,确定罗浮山薹草隶属于薹草属匏囊薹草组C. sect. Lageniformes (Ohwi) Nelmes,并更新罗浮山薹草与其近似种的检索表。
