Tropical lowland mosses disjunct between Africa and the Americas, including Calyptothecium planifrons (Ren. & Par.) Argent, new to the Western Hemisphere

ABSTRACT

Calyptothecium planifrons (Ren. & Par.) Argent is reported new to the Western Hemisphere based on two recent collections from Brazilian Amazonia, in Pará and Rondônia; C. planifrons was originally described from Madagascar. Forteen Other species of mosses with apparently disjunct distributions between tropical Africa and tropical America are also discussed. It is likely that mos or all of this species discussed will prove to have wider distributions in the tropics when world-wide revisions are carried out.
