Specimens examined:— BRAZIL. Amazonas, Manaus, RDS-Tupé, 28 August 2013, fl., fr., A. L. Corrêa 248 (EAFM!, HUAM!, INPA!); 21 April 2013, fr., A. L. Corrêa 279 (EAFM!, HUAM!, INPA!).

Distribution and habitat:— Colombia, Venezuela, Guyana, Bolivia (Goldenberg et al. 2013). In Brazil it occurs in Amazonian forests (Goldenberg & Caddah 2015). In the reserve, it occurs in “terra firme” slopes on clay soils, with a lot of organic matter.

Comments:— This species is not frequent in the reserve. It can be distinguished by the light gray and vertically scaly rhytidome, leaves with subcordate bases and persistent arachnoid trichomes on abaxial surface.
