Specimens examined:— BRAZIL. Amazonas , Manaus, RDS-Tupé, 08 December 2012, fl., A. L. Corrêa 125 ( EAFM!, HUAM!, INPA!) ; 30 January 2013, fl., fr., A. L. Corrêa 135 ( EAFM!, HUAM!, INPA!) .
Distribution and habitat:— Colombia and Venezuela ( Berry et al. 2001). In Brazil occurs in Amazonian forests (Baumgratz 2015). In the reserve, it occurs in “igapó”, on with sandy soils, where it remains under the water for a long part of the year.
Comments:— This species is rare in the reserve. It can be distinguished by the light gray and scaly rhytidome and 6-merous flowers.
