This species, the flowers of which are unknown, was compared 
by Dr. Wagner with 7’. cirrhipes, Hook. From this it is clearly 
distinguished by having the insertion of the petiole very near 
the margin. Its nearest ally seems to be 7’. Wagenerianum, Karst., 
which has relatively narrower leaves and much shorter pedicels. 
But in the total absence of flowers it is not possible to place it 
with absolute certainty.
