‘The singularly undulate superior margins of the leaves, their 
bidentate apices, and the form of the stipules, will readily distin- 
guish this species from J. horizontalis, with which it has consi- 
derable natural affinity. It is remarkable for its lengthened stalk, 
which is bare of leaves in its lower half.
