A revision of Archilejeunea s.str. (Lejeuneaceae, Marchantiophyta)
Shi, Xue-Qin; Zhu, Rui-Liang
The genus Archilejeunea s.str. was taxonomically reviewed. Six species are recognized, including five species known in tropical America and one new species, A. gradsteinii known only from Africa. The new species differs from the closely related species A. fuscescens in the usually apiculate leaf apex, mostly double subfloral innovations, and female bract lobule 1/4–1/3 as long as the bract lobe. A key to the species of Archilejeunea is provided.
