384 Mr. KipPisT on Jansonia, a new Genus of Leguminosse, 



rior, and adhering slightly to each other and to the tube of the calyx, while 

 the remaining ones are perfectly free. 



I shall now proceed to give the essential characters of the genus, which I 

 propose to dedicate to the memory of my lamented friend Joseph Janson, Esq., 

 F.L.S., whose ardent attachment to the study of natural history (which formed 

 ^ a principal relaxation of his leisure hours), and whose constant exertions to 

 infuse a taste for it in others, eminently entitle him to such a distinction ; 

 while his entire devotion to the interests of the Linnean Society, and the zeal 

 and liberality which he ever evinced in promoting its objects, give him an 

 especial claim to be commemorated in its publications.
