本文描述了省藤属的两个新的小型种，C. carsicola和C. warayanus，来自菲律宾的萨马岛和Siargao岛。尽管它们与更多变和分布更广的C。discolor和C. microsphaerion，这两个新的分类群是由一套独特的形态特征组合的区别。这些新的藤都以它们非常细长的集群习性为特征，显然仅限于石灰岩上的森林。本文提供了有关的分类学注释和世界自然保护联盟的初步保护状况。
We describe two novel diminutive species of Calamus, C. carsicola and C. warayanus, from the islands of Samar and Siargao, Philippines. Despite their respective similarities with the more variable and widely-distributed C. discolor and C. microsphaerion, both new taxa are distinctive by a suite of unique morphological character combinations. These new rattans are both characterized by their very slender clustering habit and are apparently restricted to forests over limestone. Relevant taxonomic notes and preliminary IUCN conservation status are herein provided.
