110 Mr D. Don on the Characters 



cece, especially to the genus Diapensia, with which it has many 

 points in common, both in habit and structure, and its true 

 place in the system of nature is evidently between that family 

 and Scrophularinece. 



SlBTHOBPIACEiE. 



In my observations on the genus Codon, given in a former 

 number of this Journal, I have already proposed to separate 

 Sibthorpia and Disandra as a distinct group, intermediate be- 

 tween Scrophularinea and Primulacece. To the above genera 

 I would now add JRomanzovia, Capraria, and Scoparia. They 

 are chiefly distinguished from ScrophularinecB by their regular 

 symmetrical flowers.
