296 LABIATE. (MINT FAMILY.) 



6. CALAMINTHA, Tourn., Mcench. Calajmnt. 



Our species belongs to a section with flowers verticillastrate-capitate, and 

 involucrate with conspicuous setaceous-subulate rigid bracts. 



1. C. Clinopodium, Beuth. Herbaceous, hirsute: leaves ovate, obtuse, 

 almost entire, petioled : heads globular, many-flowered : teeth of the narrow 

 tubular calyx and bracts very hirsute, nearly equalling the light purple narrow 

 corolla. — Indigenous from the Rocky Mountains to the Great Lakes, but in- 

 troduced eastward. " Basil." 



7. HEDEOMA, Pers. American Pennyroyal. 



Our species belong to the section with pedicellate flowers cymulose in the 

 axils of the leaves, the uppermost of which are often bract-like : throat of the 

 calyx in fruit closed, with a ring of hair. Pungently sweet-aromatic, with 

 small and whitish or purplish flowers. 



1. H. hispida, Pnrsh. Mostly low: leaves all similar, linear, entire, 

 thickish, nearly sessile, crowded, almost glabrous, but the margins somewhat 

 hispid-ciliate : bracts mostly equalling the calyx, rigid : calyx with teeth about 

 equal, bilabiate; the lips about half the length of the oblong gibbous hispid 

 tube; the teeth of the upper subulate, of the lower more aristiform or hispid, 

 equalling the bluish corolla — Extending into the Dakotas and southward from 

 the plains west of the Mississippi. 



2. H. Drummondi, Benth. Cinereous pubescent or puberulent, a span or 

 two high, copiously branched : leaves from oblong to linear, obtuse, subsessile or 

 narrowed into a very short petiole : subulate bracts not longer than the pedi- 

 cels : calyx hirsute or hispid, in age more or less curved, not plainly bilabiate; 

 the subulate-setaceous teeth at length all connivent ; the lower nearly twice the 

 length of the upper : corolla from little exserted to double the length of the calyx. — 

 From Texas to Arizona and extending northward to Colorado and Nebraska. 



8. SALVIA, L. Sage. 



In ours the throat of the calyx is naked : the anterior portion of the con 

 nective deflexed, linear or gradually somewhat dilated downward, closely 

 approximate or connate, and destitute of an anther-cell : corolla blue or pur- 

 plish varying to white. 



1. S. azurea, Lam. Glabrous or puberulent, 1 to 5 feet high: lower 

 leaves lanceolate or oblong, obtuse, denticulate or serrate ; upper narrower, 

 often linear, entire : inflorescence spiciform, interrupted, sometimes thyrsoidal 

 or paniculate-branched: calyx obscurely bilabiate: corolla deep blue, with promi- 

 nently exserted tube ; upper lip very concave or galeate and pubescent ; the 

 lower longer and much larger, sinuately 3-lobed and emarginate : style bearded 

 above. 



Var. grandiflora, Benth. Cinereous-puberulent : denser inflorescence 

 and calyx tomentulose-sericeous. — S. Pitcheri, Torr. From Colorado to 

 Texas and Kansas. 



2. S. lanceolata, Willd. Puberulent or nearly glabrous, branched from 

 the base, 5 to 12 inches high : leaves lanceolate or linear-oblong, obtuse, irregu-
