162 APPENDIX. 
years ago it did not escape the acute penetration of our distin- 
guished countryman Mr. Robert Brown, who then suggested 
the plan of avoiding it by the establishment of an intermediate 
family*. Another of the great botanists of our time, Mr. Ben- 
tham, who has made the Scrophulariacee one of the chief objects 
of his study, and to whom we are indebted for the admirable 
monograph of that order in the 10th volume of the ‘ Prodromus’ 
of DeCandolle, published only two years ago, although evidently 
aware of this necessity, has never carried it into execution: the 
tribe of the Salpiglossidee, which he placed at the head of the Scro- 
phulariacee, was manifestly framed under a point of view bearing 
toward this end ; and in the addenda to the same volume of the 
‘ Prodromus,’ p. 595, he offers some remarks upon what I had 
previously hinted, respecting the separation of the genus Lycium 
from the Solanacee (huj. op. p. 107). 
The establishment of the Salpiglossidee in the manner just 
mentioned, has however in no degree removed the objections be- 
fore existing, and from the facts which I shall now have to com- 
municate, these exceptions will be seen increased to a manifold 
amount, for it is now evident that a considerable number of ge- 
nera, hitherto placed in Solanaceae, possess a regular corolla, with 
a 5-lobed border, offering an imbricate estivation, contrary to the 
usual structure of the order, and although possessing five stamens, 
one is often smaller, and sometimes sterile, showing an evident 
tendency towards the structure of the Scrophulariacee ; and thus, 
besides Lycium and some of the genera of the Salpiglossidew, we 
have now Petunia, Nierembergia, Solandra, Juanulloa, Marckea, 
Hyoscyamus, Atropa, Mandragora, Nicandra, Anisodus, &e. &e., 
forming too important a number of exceptional cases to be passed 
over in neglect. Having lately examined with much care the 
structure of most of these genera, I am now better prepared to 
carry out the views, which I hinted at three years ago, in an 
earlier stage of this inquiry (Auj. op. p. 76), where I suggested 
the propriety of associating these dissident genera in a distinct 
and intermediate tribe or family. 
I therefore now propose definitely to confine the Solanacee as

: From the state of our knowledge at that time, it is evident that these allu- 
Re were intended to apply principally to the Verbascee, which by Jussieu,
