A hardy perennial, propagated by seeds and division of 
the roots. It will grow in any common garden soil. 
** Stem erect, simple, smooth, green, and glossy, varying 
in height from 1 to 2 feet. Radical leaves lanceolate, 
tapering to the base, quite smooth and entire, on long 
stalks ; cauline leaves sessile, somewhat amplexicaul, ovate- 
acuminate, passing into membranous, lacerated, acuminate 
bractex. Flowers terminal, crowded, whorled, nearly 
sessile, numerous. Segments of the calyx acute, mucronate, 
slightly lacerated or fringed. Corolla tubular, somewhat 
ventricose, pale yellow, smooth externally ; the upper lip 
2-lobed, the lower bearded with brown hairs. Stamens as 
long as the tube; anthers smooth, with divaricating lobes. 
The rudiment bearded on the upper side at the apex,
