Sphagnum magniporosum (Sphagnaceae, subgenus Subsecunda) a new peatmoss species from Venezuela

Abstract

We describe Sphagnum magniporosum sp. nov. in Sphagnum subgen. Subsecunda (Sphagnaceae) Bryophyta. The new species is described and characterized using morphological methods. The description is based on qualitative examination of morphological characters of shoots, stems, branches and leaves. The new peatmoss is known from a single locality at a tabletop (tepui) mountain in the Chimantá Massif, Canima National Park in the state Bolívar of Venezuela. The morphology of the species is compared and evaluated using keys, descriptions and illustrations of ten South American and one African Subsecunda species.
