430 LABIATAE (MINT FAMILY) 



1. Leonurus cardiaca L. Sp. PL 584. 1753. A puberulent perennial 5-10 

 dm. high: leaves long-petioled ; the lower suborbicular, dentate, 5-10 cm. 

 broad; the upper oblong-lanceolate, from incisely 3-lobed or cleft to nearly 

 entire: corolla varying from purple to white, densely white-woolly on the 

 outside of the upper lip and mottled or spotted on the lower, an oblique ring 

 of hairs on the tube within. Naturalized from Europe; waste grounds; infre- 

 quent in our range but a common weed in the older states. 



11. MONARDELLA Benth. 



Perennials (ours) with the aspect of Monarda, but not with the same floral 

 characters, with entire leaves and small purple or white flowers in terminal 

 heads which are subtended by broad, thin bracts. Calyx tubular, 5-toothed 

 and 10-13-nerved. Corolla somewhat bilabiate; the upper lip cleft; the lower 

 3-cleft into narrow similar lobes. Stamens 4, somewhat unequal, the lower 

 pair the longer; anther-cells at length divergent. Style 2-cleft at summit. 



1. Monardella parviflora Greene, PI. Baker. 3: 22. 1901. Suffrutescent at 

 base, the many slender tufted stems 3 dm. long, more or less decumbent at 

 base, or more depressed, subcinereous-puberulent : leaves mostly ovate- 

 lanceolate, some oblong-lanceolate, all entire, obtusish, nerveless except as to 

 the quite distinct midvein, obscurely puberulent, closely glandular-punctate, 

 small, half as long as the internodes, the largest seldom 12 mm. long including 

 the short petiole: heads about 18 mm. broad; bracts scarcely colored, some- 

 what strigosely pubescent along the veins and densely white-ciliate all around 

 the margin: nerves of the calyx strigose-hairy, the short teeth densely but 

 shortly setose-hirsute : corolla lilac-purple. Canon of the Gunnison and prob- 

 ably extending into Utah. 



12. STACHYS L. WOUNDWORT 



Herbs with verticillate-capitate or loosely clustered spicate flowers. In the 

 following species the calyx is equally 5-toothed and the tubular corolla purple 

 or purple-spotted. Stamens 4, ascending under the concave upper lip of the 

 bilabiate corolla; anthers approximate in pairs. 



1. Stachys palustris L. Sp. PL 580. 1753. From densely soft-pubescent 

 to roughish-hirsute ; stems 3-10 dm. high, hirsute or hispid: leaves ovate- 

 lanceolate, crenate-serrate, 4-8 cm. long, sessile or nearly so by a broad or 

 subcordate base, sometimes almost velvety-tomentose beneath: clusters of 

 the spike mostly approximate, 6-10-flowered : corolla about 14 mm. long, the 

 tube not longer than the calyx-teeth, the upper lip pubescent. Moist banks; 

 across the continent. 



13. SALVIA L. SAGE 



Herbs (ours) with flowers in terminal spikes or narrow racemes. Calyx 

 2-lippod, naked in the throat. Corolla blue or purple, varying to white, 

 strongly 2-lipped; the upper lip emarginate or 2-lobed; the lower 3-lobed or 

 3-cloft. Stamens 2; the anterior portion of the connective deflexed, linear or 

 gradually somewhat dilated downward, closely approximate or connate, and 

 destitute of an anther-cell. Nutlets smooth, often developing mucilage and 

 spiral tubes when wetted. 



Perennial; pubescent or downy 1. S. Pitched. 



Annual; glabrous or nearly so . . . . . . . . 2. S. lanceolata. 



1. Salvia Pitched Torr. in Benth. Lab. & DC. 12: 302. 1848. Tomentose- 

 pubefloent or cam-scent; stem herbaceous, 4-6 dm. high, erect, simple or 



branched above: leaves oblong-lanceolate to linear, acme, subseiTate, nar- 

 rowed to a Mlbsessile base: raceme simple, elongated, the whorls distant; 

 bracts often equaling the calyx: calyx tomentulose-sericeous; the upper lip
