I have placed the genus Verbascum in the order Scrophu- 

 lariacece, although it is still referred by many high authorities 

 to the nearly-allied family of Solanacece; the grounds of divi- 

 sion between the two are but weakly marked, and this genus 

 certainly presents a nearly equal affinity to both ; although, 

 like Celsia, it may justly be considered as the connecting link 

 between the two, yet some of its relations appear to be more 

 with the former than the latter. The principal scrophularina- 

 ceous features of the genus consist in the general habit, straight 

 embryo and imbricated corolla, the irregularity of the latter 

 organ not being included, some of the true Solanacea present- 

 ing this peculiarity, as Hyoscyamus and its allies. The chief 

 points in favour of referring Verbascum to the latter family 

 are its pentandrous stamens, and 5-lobed corolla; and the for- 

 mer character is but of secondary importance, as in Digitalis 

 there is an attempt to produce five stamens, the only point of 

 difference being that the fifth is generally abortive.

This order corresponds very nearly to the Linnaean group 

 Didynamia Gymnospermia ; two genera, Lycopus and Salvia, 

 alone forming the exceptions.
