It is difficult, if not impossible, in a plant whose leaves and sti- 
pules vary so much in different parts of the same individual as in 
the present instance, to prevent the specific character from run- 
ning to an apparently unreasonable length. poe of the leaves 
have indeed the greatest affinity to those of J. palp 
ready figured in this work, (Tas. LXXI.) while the stipules of 
the two plants have no resemblance to one another, and the ra- 
with stipule. Fig. 5, leaf from an ultimate branch with stipule.
