Pelargonium dioicum comes very near to the melanan- 

 thon of Jacquin ; and having been figured as such by Mr. 

 Andrews, is generally known by that name in our nurseries ; 

 but the radical leaves are for the most part quite entire, or 

 °nly three-lobed, which in the latter are pinnate, with the 

 Pinnae again divided ; it is also described by Jacquin as having
