Kemarkable for the perfectly epigynous perianth and the leaves with 

 lateral nerves running nearly parallel to the central one. Resembles very much 

 Asarum geopliilum HEMSL. (Dot. Mag. t. 7168) in having quite connate styles

 connectives producing to an obtuse cone, and in the quite inferior ovary ; but 

 distinguishable from it by the lanceolately ovately cordate leaves.
