 short lobes or nearly truncate : lower lip with 2 narrow lobes. Corolla white or purple, 2- 

 lipped : tube slightly narrowed at thi mouth : upper lip arched : lower lip with 2 lateral 

 lobes and a larger middle lobe. Stamens 4 : filaments various, 2 sterile, 2 forked at the 

 ttpex, one prong bearing an anther : anthers 2-celled, with divergent sacs. Nutlets smooth. 



1. Prunella vulgaris L. Stems erect or decumbent, 0.5-4 dm. long: leaf-blades 



oblong, ovate or lanceolate, obtuse or acute, undulate, gi'adually or abruptly narrowed at 



tiie base : panicles dense : bracts mostly reniform, abruptly pointed, ciliate with jointed

subulate tips, the connecting membranes undulate : corolla purple or white, 15-18 mm. 



long, glabrous or slightly pubescent, the upper lip notched, the lower lijs fringed : nutlets 



elliptic, 2 mm. long, acute at both ends.

 lip with 3 lobes : lower lip with 2 short lobes. Corolla pink or bluish, somewhat varie- 

 gated : tube somewhat dilated : upper lip erect, arched, entire or notched : lower lip 

 spreading, with 3 rounded lobes. Stamens 4 : filaments all anther-bearing : anthers 2- 

 celled ; sacs parallel or nearly so. Nutlets 3-angled, glabrous or pubescent.
