Campylopus joshii (Leucobryaceae), a new species from Africa

Campylopus joshii Broth. ex Pichonet et Bardat is described as a new species from Uganda and the Democratic Republic of Congo. The type specimen was initially named Dicranum joshii Broth. ex Thér. and Dicranum joshii var. latifolium Thér. et Naveau but these names have never been validly published. The new species resembles the groups of Campylopus species with ventral hyalocysts and a ridged costa on the dorsal side but differs by the incomplete band of ventral stereids and single-celled dorsal lamellae.
