 late to linear-lanceolate, cuspidate; cymules subsessile, 3- to 5-flowered; calyx 

 equaled by the hirsute pedicels, campanulate, strongly bilabiate, about 13 mm. long, 

 glandular-puberulent, the upper broad lip truncate and with 3 short and broad

 pidate; corolla crimson, about 4 cm. long, slightly pubescent, its tube villous- 

 annulate towards the base inside, its large and nearly straight upper lip half the 

 length of the gradually enlarged exserted tube, the middle lobe of the small lower 

 lip concave and entire; style glabrous. 



In seepage on limestone ledges and wet banks along streams in cen. Edwards 

 Plateau of Texas., June-Oct.; endemic. 



11. Monarda L. Monarda. Horsemint 



About 20 species extending from Canada to Mexico. 



Several other species, among which are M. austromontana Epl., M. punctata L., 

 M. clinopodioides Gray and M. citriodora Cerv., are occasionally found in flood- 

 plains along streams but, since they are more likely to be found in dry or moist 

 loamy soils, they are omitted here. 



1. Monarda fistulosa L. Wild Bergamont, long-flowered horsemint. Fig. 670. 



Perennial herb to 15 dm. high; stems simple or usually branched, pubescent in 

 the upper parts with downwardly curled hairs, glabrous below, sometimes with 

 longer spreading hairs, rarely glabrous; leaves gray-green, firm (except in deep 

 shade), narrowly triangular-ovate to -lanceolate, or sometimes cuneate at base, the 

 straightish serrate-dentate sides tapering to tip, definitely petioled, spreading- 

 hirsute or -villous with long hairs along the nerves beneath, the larger blades 

 to 4 cm. broad and with petioles to 15 mm. long; uppermost leaves and foliaceous 

 reflexed bracts often pink-tinged; glomerules mostly terminal, to 3 cm. broad 

 (excluding the corollas); calyx 7-12 mm. long, puberulent with short spreading 

 hairs, the acuminate teeth usually 1-2 mm. long, the orifice hirsute with stiff 

 erect hairs within, sometimes bristling with similar spreading hairs at the base 

 of the teeth; corolla lavender, 2-3 cm. long, pubescent with short soft curling 

 hairs, the upper lip comose, the tube 15-24 mm. long and gradually expanded 

 upward; stamens seated about 1 mm. within the tube. 



In dry open woods, old fields, wet meadows and ditches, alluvial thickets, 

 edge of woods and marshes in e. fourth of Tex. and Okla. {Waterfall), May-July; 

 from Que. and N.E., w. to Minn., s. to Ga., Ala., La. and Tex. 



12. PerUla L. 



About a half dozen species natives of Asia. 

 1. Perilla frutescens (L.) Britt. Beefsteak plant. 



Coarse aromatic annual, often purple or suffused with purple; stem erect, 

 branching, to about 1 m. high; leaves ovate-oblong to broadly ovate, to 15 cm. 

 long, short-acuminate at apex, coarsely serrate or incised, obtuse to rounded at 

 base but cuneately tapered into the long petiole; flowers small, purple or white, 

 borne singly in the axils of small bracteal leaves to form a loose elongate spikelike 

 1-sided raceme to 15 cm. long; bracteal leaves oval, folded, rarely greatly en- 

 larged; pedicels 1-3 mm. long; calyx campanulate, 10-nerved, bilabiate, the lips
