 West. — {Ber., Bah., Cuba, Ant.) 



3. SALVIA [Tourn.] L. Herbs or woody plants. Leaf-blades entire, 

 toothed, or lobed. Flowers in interrupted or continuous panicles. Calyx 2- 

 lipped. Corolla 2-lipped: lower lip 3-lobed, the middle lobe much larger than 

 the lateral ones. Stamens 4, but only 2 anther-bearing, or only 2: each 

 filament surmounted by a transverse connective, one end of which bears a long 

 anther.

 orbicular-ovate, 1-4 cm. long, crenate-serrate : calyx 6-8 mm. long: corolla 6-10 

 mm. long: nutlets fully 2 mm. long. — Pinelands and hammocks, and cultivated 

 grounds, L. keys, L. S. keys. — [E. K.] — {Ber., Bah., Cuha, Ant.) — Sage. 



4. MONARDA L. Annual or perennial erect herbs. Leaf -blades toothed. 

 Flowers in remote or approximate dense cymes. Calyx elongate, nearly regu- 

 lar: lobes 5, slender, shorter than the tube. Corolla 2-lipped, elongate: upper 

 lip narrow, erect or arched : lower lip 3-lobed, the middle lobe much larger than 

 the lateral ones. Stamens 2 : filaments elongate : anthers with divergent sacs. 



1. M. punctata L. Stems 3-10 dm. tall, finely pubescent: leaf-blades linear- 

 oblong to lanceolate, 2-8 cm. long, serrate: caiyx 8-10 mm. long; lobes short- 

 acuminate, spreading: corolla yellowish and purple-spotted (white in M. 

 punctata leucantha), 20-25 mm. long; upper lip mainly oblong-ovate. — Ham-

 toothed. Flowers in raceme-like panicles. Calyx strongly 2-toothed: upper lip 

 a broad lobe: lower lip of 2, broad lobes and 2 narrow lobes. Corolla slightly
