MINT FAMILY 387 



ceolate, twice as long as the tube ; corolla pale blue or whitish, marked with a few 

 purple dots, slightly hairy inside on palate, 3 to 4 lines long; nutlets reticulately 

 ridged on back, the scar flattish. 



Grassy spots under the shade of trees or bushes in desert basins or river bottoms, 

 in sandy or dry alkaline soil, 100 to 500 feet : eastern Riverside Co. East to New 

 Mexico. Nov. -Apr. It resembles Verbena bracteata in habit.

Teucrium occidentale Gray, Sjti. F1. 2:349 (1878), type loc. "Nebraska (Hayden, etc.)." 

 Erect, 1 to 2 feet liigh; herbage loosely pubescent; leaves ovate-oblong, entire, sharply serrate; 

 calyx vUIous-\T.scid, merely 5-toothed. — New Mexico to British Columbia and Ontario. "Sacra- 

 mento River, Pickering," in 1841 (Bot. Cal. 2:477), but not since found ui California, although 

 regularly reported as Californian in subsequent floras of neighboring states. 



2. T. glandulosum Kell. Perennial, the stems few or several from a woody 

 root-crown, erect with long simple branches, 1 to 2 feet high; herbage glabrous, 

 non-glandular; leaves sessile or subsessile, the blades % to 1^/4 inches long, linear 

 or lanceolate, entire or remotely serrulate, or those above the base palmately 2 or 

 3-parted into lanceolate or linear lobes ; racemes loose, the flowers remote, borne in 

 the axils of lanceolate bracts, their pedicels 5 to 7 lines long ; stamens conspicuously 

 exserted, ascending and curved; corolla whitish or "blue," 6 to 9 lines long, the lip 

 partly puberulent above and pilose on back; nutlets with rows of shallow pits on 

 the back, hairy at apex, the scar with a central nipple-like protuberance. 



Among rocks in shady moist places of cations, 1400 to 1500 feet : southeastern 

 San Bernardino Co. South to Lower California. Apr. -May. 



Note on range. — The range of Teucrium glandulosum is not yet vpell established. From Ced- 

 ros Island, the type locality, several collections are known and a few have long been known from 

 the mainland of Lower California: San Pablo, Purpus 57; San Jorge, San Julio Canon (Proc. 

 Cal. Acad. ser. 2, 2:198). In California it was not, however, until 1935 that a single station was 

 discovered in the Whipple Mountains along the Colorado River by F. W. Peirson. In collections 

 from Lower California the stems and leaves are commonly glabrous and non-glandular (as in Cali- 

 fornia plants), but the stems may rarely bear very thin and localized areas of glandular-pilose hairs.

2. TRICHOSTEMA L. Blue Curls. 



Ours ill-scented annual herbs or small shrubs with entire leaves and blue (occa- 

 sionally pinkish or whitish) flowers in axillary cymes or the cymes often becoming 

 raceme-like in age. Calyx equally or almost equally 5-cleft. Corolla with oblique 

 limb, the upper and lateral lobes alike (oblong or ovate), the middle lobe of lower 

 lip similar or markedly different ; tube in ours slender, often far exceeding the calj'x 

 and abruptly geniculate or curved into an arc of a circle just below the limb. Sta- 

 mens 4, with the anther-cells divaricate; filaments capillary, blue or violet, spirally 

 coiled in the bud, in anthesis very much exserted, ascending between the deeply 

 parted upper lobes of the corolla and curved outward and downward. Nutlets 

 pyriform, obliquely attached to the receptacle, rugose-reticulate on back, and often 

 papillate on the summit. — Species 11, North America. (Greek trichos, hair, and 

 stemon, stamen.) 



A. Annuals; cymes home in the axils of the leafy stems. 



Corolla 1 to 3 lines long, tube included in the calyx; nutlets rugo.se-reticulate (the ridges always 

 evident), less than 1 line long (to 114 lines in T. simulalum). 

 Herbage cinereous-pubescent ; leaves linear to lanceolate, not costate-veined ; corolla 1 line 

 long : 1. T. micranthum.
