The genus Phlegmariurus Holubis recognised more widely than originally proposed and is circumscribed to include both Neotropic and Palaeotropic epiphytic and terrestrial species of Huperzioid Lycopodiaceae that have isotomous shoots, lack bulbils in their sporophyllous shoots and have spores with convex lateral margins and foveolate-fossulate sculpture restricted to their distal surfaces. New combinations with Phlegmariurus are proposed for 81 species and existing combinations identified for 33 species originating from the Palaeotropics. This installs a generic circumscription that is consistent between the Neotropics and Palaeotropics. A lectotype is designated for the type species of the genus, Phlegmariurus phlegmaria (L.) T.Sen & U.Sen.
扁枝石松属（Phlegmariurus）比最初提议的范围得到更广泛的认可，其范围界定为包括新热带界和古热带界石松科扁枝石松亚科的附生和陆生物种，这些物种具等二叉分枝的枝条，孢子叶枝上无小鳞芽，孢子具凸的侧边，且仅在远端面有蜂窝状-瘤状纹饰。为81个物种提出了与扁枝石松属相关的新组合，并确定了33个源自古热带界物种的现有组合。这确立了新热带界和古热带界之间一致的属范围界定。为该属的模式种扁枝石松（Phlegmariurus phlegmaria (L.) T.Sen & U.Sen.）指定了一个选模式。
