Scrophularia serrata sp. no v. 



Perennial ; stem 1--2 m. high, angled, sparingly puberulent or 

 glabrous, slightly glandular in the inflorescence ; leaf-blades ovate 

 or cordate, 5-15 cm. long, regularly serrate with the teeth directed 

 forward, acute or short-acuminate, minutely glandular-puberulent 

 on both sides ; bracts rather conspicuous, linear-lanceolate, the 

 lowest 2-3 cm. long ; calyx-tube hemispheric, glabrous or nearly 

 so, 2 mm. long ; lobes rounded, 2 mm. long ; corolla-tube short, 

 6-7 mm, long, nearly 5 mm. thick ; upper lip 4-5 mm. long ; 

 sterile stamen obovate-spatulate,. purple. 



This species is related to Scrophnlaria marilandica and S. 

 neglecta. From both it differs in the stout, strongly ascending, 

 instead of more or less spreading branches of the inflorescence ; 

 from the former in the larger corolla (about twice as large) and 

 from the latter in the shorter corolla-tube, scarcely twice as long 

 as the calyx, and the finely glandular-puberulent, instead of densely 

 pubescent lower leaf-surfaces. In ^. iieglecta the corolla-tube is 

 about three times as long as the calyx. S. occidentalism the common 

 Rocky Mountain species, has doubly toothed or incised leaves 

 with spreading teeth and a renlform greenish sterile stamen.
