A new variety of Blechnum gracile Kaulf. (Blechnaceae) for the Guianas and Venezuela.

Within the framework of the study of the biodiversity of the Guianas, a new variety, Blechnum gracile Kaulf. var. pilosum, is described. Characterized by its rachis bearing numerous 1 mm long, translucent and septate hairs, it is known, until now, from French Guiana, Suriname and western Venezuela, on mossy rocky cliffs close to summits or inselbergs mainly at 450-1100 m elevation.
