Diagnosis. — Similar in size and overall aspect to Nowellia pusilla,

but differing from it by the entire-margined leaves without any

tooth-like or ciliate appendage, leaf lobes made of a single row of

elongate cells from base to apex, and leaf lamina conduplicate with

an ovoid, fully inflated lobule and a rounded keel typically ornamented

by strongly protruding mammillose cells, the mammillae

rounded to conical in shape.
