 and glandular-dotted, becoming 8-9 mm. long ; tube nearly straight, finely ribbed, bristly 

 about the throat ; lobes subulate, about 1 mm. long : corolla lilac or purplish, villous and 

 glandular-dotted, 1.5-2 cm. long, the lower lip crisped, its narrow middle lobe bearded : 

 nutlets nearly 1.5 mm. long.

6. Monarda scabra Beck. Perennial, closely velvety-pubescent. Stems 2-10 dm. 

 tall, commonly branching above : leaf-blades firm, ovate to lanceolate, 2-8 cm. long, acute 

 or slightly acuminate, sharply often rather remotely serrate, rounded, truncate or cordate

 ally dilated, the upper lip linear-lanceolate, conspicuously bearded at the apex, the lower 

 lip 3-lobed at the apex, its middle lobe linear, notched : nutlets about 1.5 mm. long. 



On dry plains and prairies, Northwest Territory and British Columbia to Missouri, Texas and Ari- 

 zona. Summer. 



7. Monarda rndllis L. Perennial, similar to M. fistulosa in habit and to M. scabra 

 in its short close pubescence. Stems finely and often copiously puberulent-canescent : leaf- 

 blades ovate to lanceolate, coarsely serrate, usually gradually or abruptly narrowed at the 

 base ; petioles slender, those of the lower leaves 1-1.5 cm. long, those of the upper some- 

 what shorter : heads subtended by bracts more or less colored like the corollas. 



In dry soil, New England to South Dakota, Georgia and Texas. Summer. 



8. Monarda Bradburi^n a Beck. Perennial, villous-hirsute above, or glabrate. Stems 

 3-6 dm. tall : leaf-blades ovate to lanceolate, 3-10 cm. long, acute or acuminate, ciliate,
