Redout. I. c. So incomplete is the account given in Redouteswork of this most interesting phmt, that it is quite im-practicable to ascertain with certainty, even the divisionin which it should be arranged. The figure is probablytaken from a dried specimen and is very like R. rubigi-nosa; yet the leaves are described as naked on bothsides. If it be really an unarmed species, it will beeasy to characterize it; but if, as I believe, it is onlyan unarmed branch that is figured, and if it do not be-long to this division, it must be placed in the next;but then I do not perceive how it is to be distinguishedfrom R. canina.

The essential dif-ferences which distinguisii it from the preceding Divisions havebeen explained under their respective heads. Mr. Sabine has aplant of R. caiiina which produces setae ; but this is a solitary ex-ception and cannot affect the general importance of the characterI Iiavc assigned to the section. 54.
