Monarda comata sp. nov. 



Perennial with a horizontal, slender rootstock. Stem obtusely 

 4-angled, 4—6 dm. high, simple, sparingly silky-villous, especially 

 below the nodes and on the upper portion : lower leaves with more 

 or less hairy petioles, which are about i cm. long, the upper sub- 

 sessile ; blades ovate or lance-ovate, more or less cordate at the 

 base, acute or acuminate, serrate with small teeth which are di- 

 rected forward, 4—6 cm. long, sparingly silky-strigose on both 

 sides: bracts green or tinged with purplish, ovate, 1—2 cm. long : 

 calyx about i cm. long, minutely puberulent, with a ring of hairs 

 at the base of the teeth, which are subulate, .7 mm. long: corolla 

 red-purple, almost wine-color, densely villose-puberulent, the ex- 

 serted portion about 2 cm. long. 



This is nearest related to M. stricter Wooton, but differs in the 

 long pubescence of the stem, leaves and bracts, shorter calyx-teeth 

 and darker flowers. It grows in meadows among bushes, at an 

 altitude of 2000-2500 m.
