Drepanolejeunea glimeae (Marchantiophyta: Lejeuneaceae), a new species from the lowland rainforests of Brunei Darussalam

Abstract

A new species, Drepanolejeunea glimeae (Marchantiophyta: Lejeuneaceae), is described and illustrated from Brunei Darussalam. It was discovered in the lowland rainforests in Ulu Temburong. This new species is distinguished by the absence of gynoecial innovations, erectly to obliquely spreading underleaf lobes, large leaf lobule about 1/2 as long as the lobe, acute to obtuse apex of the leaf, occasional occurrence of ribbon-like regenerants at leaf margins, and occasional presence of ocelli in the female bracteole.
