298 LABIATE. (MINT FAMILY.) 



reduced to short ovate and acuminate bracts : calyx-teeth more or less 

 colored. 



1. L. anisatus, Benth. Glabrous or very minutely puberulent, 2 or 3 

 feet high : leaves ovate, often subcordate, canescent beneath, anisate-scented 

 when crushed: spike short and narrow, interrupted, sometimes leafy below 

 and paniculate : calyx-teeth ovate-lanceolate and merely acute, tinged with 

 purple or violet : corolla blue. Plains, from the Saskatchewan to Nebraska 

 and westward to the mountains. 



2. L. urticifolius, Benth. Like the last, but leaves green both sides, 

 mostly crenate and more or less cordate, sweet-aromatic : calyx-teeth lanceo- 

 late, subulate-acuminate : corolla light violet or purplish. Western slopes of 

 the mountains to Oregon and California. 



11. DRACOCEPHALUM, Tourn. DRAGON-HEAD. 



Herbs, peculiar for the small and included corolla. 



1. D. parviflorum, Nutt. Rather stout, 6 to 20 inches high, some- 

 what pubescent : leaves lanceolate or oblong, petioled, incisely dentate, or the 

 lower pinnatifid-incised ; the lower floral similar: flowers numerous in sessile 

 glomerules crowded in a thick terminal leafy-bracted head or short spike in- 

 terrupted at base : bracts pectinate-laciniate and the teeth aristate : corolla 

 bluish, slender, hardly exceeding the calyx. New York to British Columbia, 

 and southward along the mountains to New Mexico. 



12. SCUTELLARIA, L. SKULLCAP. 



Flowers mostly blue, solitary in the axils of the leaves, or in spikes or 

 racemes from the reduction of the floral leaves to bracts. 

 * Flowers small (\ inch long), in axillary and sometimes also terminal racemes. 



1. S. lateriflora, L. Glabrous, a foot or two high, leafy: leaves thin, 

 oblong-ovate and ovate-lanceolate, acuminate, coarsely serrate, rounded at 

 base, slender petioled ; the lower floral ones of the terminal racemes similar : 

 lips of the corolla short, equal in length. From Oregon to New Mexico and 

 eastward across the continent. 



* * Flowers solitary in the axils of the cauline leaves, or some occasionally 

 imperfectly racemose, violet-blue. 



2. S. resinosa, Torr. Barely a span high, branched from the base, mi- 

 nutely pubescent and resinous atomifcrous, somewhat viscid : leaves uniform, 

 oval or oblong, obtuse, mostly sessile, 5 to 10 lines long, nervose-veined : corolla 

 pubescent, an inch long, with slender tube and ampliate throat. Plains of 

 Nebraska, Wyoming, and Colorado. 



3. S. galericulata, L. Nearly glabrous or slightly pubescent, slender, 

 1 to 3 feet high, simple or paniculately branched above : leaves ovate-lanceolate, 

 broadest next the subsessile subcordate base, 2 inches or less long, all but the 

 upper appressed-serrate : corolla puberulent, to inch long ; lower lip nearly 

 erect and surpassing the upper. From British Columbia to Arizona and 

 eastward across the continent.
