604 LABIATE. Scutellaria. 



Plains and hillsides, rather common from Monterey Co. northward ; beginning to blossom in 

 February. Varying greatly in size. Upper flowers in vernal specimens sometimes much exceeding 

 the leaves, on the longer trailing stems much exceeded by them. 



6. S. nana, Gray. Depressed, cinereous-puberu^ent throughout : stems tufted on 

 the filiform subterranean shoots, 2 or 3 inches high : leaves thickish, obovate or 

 ovate, very obtuse, entire, half an inch long, tapering into a short petiole, equalling 

 the flowers : pedicels very short : corolla " white," half an inch long, rather broad, 

 and with short equal lips. Proc. Am. Acad. xi. 100. 



On a clay ridge, Winnemucca Valley, near Pyramid Lake, N. W. Nevada, Lemmon. Tubers 

 copious, moniliform, an inch or two long. Corolla appearing purplish in the dried specimens, 

 said to be white. 



14. SALAZARIA, Torr. 



Calyx at first carnpanulate or oblong, with two entire lips and no gibbous projec- 

 tion on the back, in fruit much enlarged and globose-inflated, thin and bladdery, 

 reticulated, closed. Corolla, stamens, &c., as in Scutellaria. Upper fork of the style 

 wanting. A single species. 



1. S. Mexicana, Torr. Shrubby, 2 or 3 feet high, with slender and divaricate 

 straggling branches, somewhat sarmentose, canescent : leaves becoming green and 

 glabrate, ovate-lanceolate or oblong, mostly entire, an inch or less in length, on short 

 slender petioles ; those of the flowering branches reduced to bracts of the loose 

 raceme or spike : corolla purple or whitish, nearly an inch long, pubescent : scarious 

 fruiting calyx over half an inch in diameter : nutlets depressed, minutely muricate.

15. BRTJNELLA, Tourn. SELF-HEAL. 



Calyx oblong, about 10-nerved and reticulate-veiny, bilabiate; the lips flattened 

 and closed in fruit ; the upper dilated, truncate and 3-toothed, its teeth very broad 

 and short ; lower 2-cleft, the teeth lanceolate. Corolla with ascending tube, open 

 lips, and slightly contracted orifice : upper lip arched and entire ; lower 3-lobed, its 

 middle lobe drooping, rounded, concave, denticulate. Stamens 4, ascending under 

 the lower lip : filaments 2-toothed at the apex, the lower tooth bearing the 2-celled 

 anther, the cells of which are divergent. Nutlets smooth. Low perennials, of 

 two or three very similar species : the flowers crowded in a terminal oblong or cylin- 

 draceous head or spike.
