256 CLASS XIV. ORDER 1, 



Syn. Prunella Pennstlvanica. 1st Edit. 



A handsome plant, native of meadows and moist pastures. 

 Stem nine or ten inches in height, hairy. Leaves opposite, 

 broad-lanceolate, slightly toothed, their nerves and petioles hairy, 

 the upper pair close to the spike and sessile. Spiice short, ovate. 

 Bractes reniform, ciliate, acuminate. Flowers ringent, purplish. 

 Calyx two lipped, the upper lip broad and abrupt, with three 

 straight, short bristles or awns ; the lower lip ending in two 

 acute teeth. Upper lip of the corolla arched, lower lip three 

 lobed, the middle lobe fringed. — July, August. — Perennial.
