Caules $—2-pollicares vage ramosi. 
Folia subimbricata plana vel seepius subtortilia crispulave, semiovata 
acinaciformia plerumque rotundata, toto ambitu grossiuscule spinoso- 
dentata—dentibus posticis paucis, sub 4, sinubus latis profundis, 
medio precipue, anticis crebrioribus minoribus—margine postico in-

Obs. The postical margin of the leaves has usually only four teeth, 
and the gap between the second and third tooth is so wide and deep— 
extending to nearly one-third the length of the leaf—that it looks as if a 
piece had been cut out artificially.

Obs. The fertile branches, although short, innovate many times, there 
being only a pair of leaves between two consecutive ? flowers, which 
stand alternately right and left of the branch,
