 row, usually toothed, at least near the apex. Flowers in spike-like racemes. 

 Calyx essentially regular: lobes 5, shorter than the tube. Corolla 3-lipped: 

 upper lip arched, entire: lower lip 3-lobed. Stamens 4: filaments elongate, one 

 pair, at least, glabrous. 



1. D. leptophyllum Small. Stems 6-10 dm. long: leaf -blades thin, oblong or 

 nearly so, mostly 3-7 cm. long, repand: calyx-lobes lanceolate to triangular- 

 lanceolate: corolla 20-23 mm. long: nutlets 3-3.5 mm. long. [Physostegia

5. 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. 



1. S. serotina L. Stems 1-7 dm. tall, finely pubescent: leaf -blades ovate to 

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

 mm. long: nutlets fully 2 mm. long. Pinelands. F. K. (Ber., Bah., Cuba, 



Ant.) SAGE. 



6. PYCNOTHYMUS Small. Shrubs. Leaf-blades narrow, entire. 

 Flowers in dense raceme-like panicles. Calyx slightly irregular, the upper lip 

 with 3 narrow lobes, the lower lip with 2 longer lobes. Corolla 2-lipped: lower 

 lip 3-lobed, the middle lobe slightly larger than the lateral ones. 



1. P. rigidus (Bart.) Small. Plants 1-7 dm. tall, hirsute: leaf -blades lanceo- 

 late, 5-12 mm. long: calyx 2.5-3 mm. long; lobes lanceolate to oblong-lanceo- 

 late: corolla light-purple, 7-8 mm. long; lobes rounded. Pinelands. 



7. HYPTIS Jacq. Herbs or woody plants. Leaf-blades commonly 

 toothed. Flowers in often dense axillary cymes. Calyx nearly regular, some- 

 times oblique, accrescent and ribbed or veiny at maturity. Corolla 2-lipped: 

 lower lip 3-lobed, the middle lobe saccate. [Mesosphacrum P. Br.] 



1. H. radiata Willd. Stems 5-12 dm. tall: leaf -blades ovate to lanceolate or 

 linear-lanceolate, 2-8 cm. long, remotely serrate : calyx 3-5 mm. long, becoming 

 about 8 mm. long; tube strongly cross-ribbed at maturity: corolla 8-10 mm. 

 long: nutlets about 1.5 mm. long. Everglades and low pinelands. 



8. OCIMUM [Tourn.] L. Herbs or woody plants. Leaf-blades often 

 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 

 2-lipped: lower lip of 3 nearly equal lobes. 



1. O. micranthum Willd. Stems 2-5 dm. tall, branched: leaf-blades ovate to 

 oblong-ovate, 1-4 cm. long, serrate: panicles continuous or nearly so: calyx 2 

 mm. long, becoming 6-7 mm. long, the lower lip with subulate-tipped lobes: 

 corolla white, pink, or purplish, 4 mm. long; upper lip minutely bearded, lower 

 lip with a notched middle lobe: nutlets about 1 mm. long. Pinelands. F. K.
