858 ANTIRRHINUM. [CLASS XIV. ORDER II. 



This beautiful species of Scrophularia is very different in appearance 

 from our other species, and as Sir J. Smith has well observed, bears a 

 great affinity to some of the species of Calceolaria, which beautiful 

 tribe of plants we may observe belong to the same natural order, but 

 differ in generic character in having only two stamens, while the 

 Scrophularia have four.

 tapering into a footstalk, dark green above, paler beneath, with a

 crowded flowers. Bracteas ovate, downy. Pedicles round, short,
