Phlegmariurus is a genus of lycophyte plants in the family Lycopodiaceae.[1] The genus is recognized in the Pteridophyte Phylogeny Group classification of 2016 (PPG I),[2] but not by some other sources, which keep it in a broadly defined Huperzia.

Taxonomy

[edit]

The genus was first described in 1909 by Wilhelm Herter as the section Phlegmariurus of the genus Lycopodium. The section was elevated to a genus by Josef Ludwig Holub in 1964.[3]

Within the family Lycopodiaceae, Phlegmariurus is placed in the subfamily Huperzioideae. A phylogenetic study in 2016, employing both molecular and morphological data, concluded that either a one-genus or a three-genus division of the subfamily produced monophyletic taxa. The authors preferred the three-genus division, recognizing Huperzia, Phlegmariurus and Phylloglossum. Their preferred hypothesis for the relationships of the three genera was:[4]

Huperzioideae

Phlegmariurus

The majority of the species formerly placed in a broadly defined Huperzia belong in Phlegmariurus.[4] However, the genera are difficult to separate morphologically, and others have preferred the one-genus division of the subfamily.[1]

Species

As of June 2024, the Checklist of Ferns and Lycophytes of the World accepted over 300 species:[1]
