858 ANTIRRHINUM. LCLASS *1Y. ORDER 11. 



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.

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

 downy. Calyx in five ovate oblong downy segments, unequal in

 waved on the margin, the lower in three reflexed roundish ovate 

 unequal lobes, the palate large, swollen in two protuberances, yellow, 

 furrowed and downy between. Stamens included, arising from the 

 base of the tube, the filaments linear, somewhat dilated upwards. 

 Anthers of two ovate cells, and between the two upper ones is a fifth 

 abortive stamen. Style as long as the lower stamens, linear, downy. 

 Stigma obtuse. Capsule obliquely ovate, opening by three pores near 

 the apex. Seeds numerous, small, black, and wrinkled.
