New synonyms and national records for Lejeunea (Lejeuneaceae, Marchantiophyta) in Tropical America

Abstract

New synonyms, morphological characterizations and national records for three neotropical Lejeunea species, including comments on distribution and ecology, are presented. Lejeunea cristulata (Steph.) M.E.Reiner & Goda (= L. resupinata [Steph.] Steph., syn. nov.) is newly recorded for Venezuela, Peru and Bolivia. Lejeunea diversicuspis Spruce (= L. megalantha Spruce, syn. nov.; = L. erostrata M.E.Reiner & Goda, syn. nov.) is until now only known from type materials collected by Richard Spruce at the Rio Negro and is new to Venezuela. Lejeunea laeta (Lehm. & Lindenb.) Lehm. & Lindenb. (= Lejeunea diversistipa Lindenb. & Gottsche, syn. nov.) is newly recorded for Venezuela, Peru and Bolivia, and is newly lectotypified. A list of new names in Lejeunea published since the appearance of the World Checklist of Hornworts and Liverworts is presented.
