A Revision of Streptopogon Wils. (Pottiaceae)
Abstract
Streptopogon Wilson in Mitt. (Pottiaceae) is an acrocarpous moss genus containing seven species, which occurs in tropical to subtropical areas. The center of diversity for Streptopogon is in the Neotropics, specifically the Andes of Colombia and Ecuador. More common species occur in central Africa, Madagascar, and New Guinea. The single, haplolepideous peristome with a high basal membrane, and 32 long, twisted, teeth in Streptopogon retains the genus in the Pottiaceae. Unifying generic characters include scabrous, mitrate calyptrae, short, twisted setae, exserted (or emergent) wide, cylindrical capsules, a strong, single costa with a single stereid band, and smooth leaf cells. Keys, descriptions, illustrations and distribution maps have been provided for all species.

Distribution Maps
Most species of Streptopogon are morphologically distinct. There are several different kinds of asexual structures in the genus which are characters essentially diagnostic to species. However, the propagulae are not always present, so a dichotomous key is provided which focuses on other characters.
