xxx Segmentis inferioribus, seu minoribus, saccaiis. 
71. J. Hutchinsia, caule repente, ramoso: foliis inaequaliter bilobis ; lobis superioribus 
ovatis, spinuloso-serratis ; inferioribus minutis, saccatis, basi srepissimfe unidentatis; 
stipulis rotundato-ovatis, subserratis, acute bifidis : fructu laterali ; calycibus obcor- 
datis, triangularibus. (Tab. i.) 
Mr. Mackay has found this species in the south of Ireland, SirT. Gage upon mountains 
about Killarney, and Mr. Lyell upon rocks, near Lowdore, Cumberland. 
72. J. dilatata, caule repente, vagb ramoso : foliis inaequaliter bilobis ; lobis superioribus 
subrotundis ; inferioribus rotundatis, saccatis ; stipulis rotundatis, planis, emargi- 
natis : fructu terminali ; calycibus obcordatis, tuberculatis, triangularibus. (Tab. v.)

superioribus ovato-rotundatis ; inferioribus minutis, obovatis, saccatis ; stipulis sub-

After a careful examination of numberless specimens, upon their native mountains, of 
what foreign authors have called by the name of J. palmata, I can see no reason whatever 
for separating it from J. multifida, nor even for considering it a variety of that plant.
