Gesnerece, from which it had, with apparent reason, been 

 removed {Gen. Plant, II., p. 960), as agreeing with Onrisia 

 in several important details. 



I have brought here to exhibit with the specimens of 

 Wulfenia from my herbarium, examples of all these genera 

 excepting two, viz. : Camptoloma, of which only one specimen 

 has ever been gathered, and CalorJiabdos, which, as being so 

 near an ally of Wulfenia, I am sorry to have been unable to 

 procure. As a substitute, however, I exhibit a plate of two 

 species of the genus. 



We here in Lancashire can boast of, perhaps, the hand- 

 somest of the whole series, as it is the type, viz., Digitalis 

 purpurea, to the Purple Foxglove, being one of the most 

 plentiful plants in the neighbourhood, often, as at Prestwich, 

 monopolizing everything else, self-sown, in a shrubbery, or 

 open space, and ornamenting many a woodside in the 

 summer. Many species of Veronica likewise abound 

 around us. 



The genera have been placed with much care and 

 circumspection by the learned authors of Gen. Plantarum : 

 and there can be no doubt but that the nearest allies of 

 Wulfenia are 



Ourisia, - - Stamens 4 



Picrorhiza, - - „ 4 



Synthyris, - „ 2 



CalorJiabdos, - - „ 2 



and Pcedarota, - ,,4 



this last showing a decided link between this plant, and the 

 spicate Veronica? (Pseudolysimachia, Bentham, Leptandra, 

 North), the first mostly natives of Europe and Asia, the 

 latter of North America. 



Pcedarota, Linn, in its two species P. Ageria, L. 

 and Bonarota, L., with the hybrid between the two, 

 named by Huter P. CJiurchilli in honour of Mr. G. C.
