mtJi Remarks on their Affinities, (^^ ^y; 51 



cui calyce petalis unguiculatis insequalibus seminibusque ex albuminosis huic 

 similis ; inde vero cruciferis monospermis, ovulis solitariis, seminum fabrica, 

 foliis altemis exstipulatis, et herbte sapore. 



The preceding description of Tovaria accords so well with 

 the leading characters of Capparidea, that the propriety of 

 placing it in that family, must be generally admitted, and an 

 interesting addition it proves, as it points out several analogies 

 and affinities between Capparideee and the neighbouring orders, 

 not before indicated. It must be placed near to Cratceva and 

 Morisonia, to both of which it approximates in the structure of 

 its fruit ; but in habit it comes nearer to Cleotne, and the struc- 

 ture of its stigma shews at least an analogy, if not an affinity, to 

 the Papaveracece. In the form and structure of its seeds, it 

 accords precisely with Reseda, which I am still inclined to think 

 with M. de Jussieu might be, without much violence to natural 

 affinities, again referred to Capparidece. The CapparidecB, 

 ResedacecB, Cruci/erce, PapavercLcece, and TropcEolece, appear 

 to constitute a grand natural class ; and near to them, but at 

 different points, must be arranged the Ramtnculacea, Poly- 

 galea., and Balsaminea, — an arrangement which the many ana- 

 logies and affinities existing between these families appear to 

 justify.
