Mr D. Don on the Characters 



ceo?, 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. 



SIBTHORPIACEiE. 



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 Scrophularinece and Primulacece. To the above genera 

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

 are chiefly distinguished from Scrophularinece by their regular 

 symmetrical flowers.
