Abstract

Sparganium coreanum, a barely recognized species in Korea, was rediscovered during a field survey by the authors, who conducted a re-examination of specimens deposited in the Herbarium of the Korea National Arboretum (KH). This species was described initially by H. Leveille from a specimen collected by F. Taquet from Jeju-do (Taquet 2150). Subsequently, however, it was overlooked and unrecognized among South Korean flora. Several populations of S. coreanum were found in the southern part of the Korean Peninsula and on Jeju-do, although it has long been recognized as S. erectum owing to certain vegetative morphological characteristics shared between the two species, such as robust stems, a similar plant height, and globose rhizomes. However, it is distinct from S. erectum by the number of female heads on the lowest inflorescence branch and the size and shape of the fruit. In this study, we provide a detailed description, illustrations, and photographs with a revised taxonomic key for identification of Sparganium species in Korea.
朝鲜半岛重新发现的三棱(香蒲科)札记
作者们对保存在国立植物园植物标本馆的标本进行了重新检查,并在野外调查中重新发现了在国内几乎不为人所知的种——谷草(Sparganium coreanum)。本种最初由H. Leveille从F. Taquet从济州岛采集的标本中描述(Taquet 2150)。然而,它后来在韩国植物群中被忽视和不被认识。在朝鲜半岛南部和济州岛发现了几个coreanum种群,尽管由于两种物种之间共享的某些营养形态特征(如粗壮的茎,相似的植物高度和球状根茎),它一直被认为是S. erectum。然而,在最低的花序分支上雌蕊头的数量和果实的大小和形状上,它与雄蕊不同。本研究提供了详细的描述、插图和照片,并附有修订的分类索引,用于鉴定韩国的Sparganium种。
