 Mexico and Mexico. Spring and summer. Naturalized eastward. 



14. Monarda tenuiaristata (A. Gray) Small. Annual and similar to M. dwpersa in 

 habit, but relatively more slender : leaf-blades mainly tapering to the base : bractlets typi- 

 cally lanceolate or linear-lanceolate and gradually narrowed into the terminal bristle: 

 calyx-tube 7-8 mm. long, puberulent, the lobes setaceous, sparingly ciliate, spreading : 

 corolla about 2 cm. long : nutlets about 1.5 mm. long. [M. aristaia Nutt., not Hook. M.

 branched at the base, the branches closely pubescent : leaf-blades oblong to narrowly linear- 

 oblong, 2-5.5 cm. long, sharply serrate : bractlets elliptic or lanceolate-elliptic, gradually 

 narrowed into the terminal bristle, pubescent on the back and copiously ciliate : calyx-tube 

 pubescent, 6-7 mm. long, the lobes setaceous, erect, plumose-ciliate : corolla 2-2.5 cm. 

 long: nutlets 1.5 mm. long.

24. BLEPHILIA Raf. 



Perennial caulescent herbs, with pubescent foliage. Leaves opposite : blades flat, 

 usually shallowly toothed. Flowers in dense remote or contiguous axillary clusters. Calyx 

 glabrous in the throat, 2-lipped : tube nearly tubular, 13-nerved : lobes of the lower lip 

 much longer than those of the upper. Corolla bluish or purplish, much longer than the 

 calyx : tube glabrous within : upper lip erect, entire : lower lip 3-lobed, spreading : fila- 

 ments various, 2 anther-bearing, sometimes exserted ; the other 2 reduced to staminodia 

 or wanting : anthers 2-celled ; sacs somewhat confluent at the base. Nutlets smooth. 



Foliage softly pubescent with short hairs : leaf-blades shallowly toothed. 1. B. ciliata.
