Abstract

Cololejeunea yelitzae, member of subgen. Incalejeunea is described from Venezuela, as new to science. It is characterised by the very variable leaf width from wide ovate to narrow lanceolate within the same plant, by the acute leaf apex and by its acute lanceolate lobule with a wide gap between the 1st and 2nd teeth. Gemmae abundantly develop on leaf surface and even on the perianth. It is widely distributed in the mountain areas from Costa Rica to Bolivia. With this new taxon the known number of Neotropical Cololejeunea species is raised to 71.
