 at the base. Ovary deeply 4-lobed; style 2-cleft at the 

 summit. 



1. T. lanceolatum Benth. Strong-scented annual, simple or 

 branching from near the base, 1.5-3 dm. high, very leafy, herbage 

 cinereous or villous-pubescent and minutely glandular; leaves 

 lanceolate, acuminate, sessile or the lowest subsessile, with 3-5 strong, 

 nearly parallel nerves, 2 cm. long; cymes short-peduncled or nearly 

 sessile; calyx villous; corolla almost filiform, somewhat pubescent, 

 blue. 



Frequent in dry fields, especially on the mesas in interior 

 valleys. June-September. 



2. T. lanatum Benth. (Romero or Woolly Blue-curls.) 

 Shrubby, about 1 m. high, very leafy; leaves thickish, narrowly 

 linear and with revolute margins, 1-nerved, glabrate and shining 

 above, canescent-tomentose beneath, sessile, many fascicled in the 

 axils, uppermost reduced to bracts; cymes in a naked terminal, 

 interrupted thyrsus, whole inflorescence clothed with a dense violet 

 or purple wool; corolla 1 cm. long; the filaments fully twice as long. 



Occasional in the chaparral belt on dry ridges in all the mountain 

 ranges and extending northward as far as Monterey County. 



2. SCUTELLARIA L. Skullcap. 



Annual or perennial herbs, with flowers solitary or 

 2-3 together in the axils or in bracted racemes or spikes. 

 Calyx campanulate, gibbous, bilabiate, the lips entire, 

 the upper with a crest or protuberance upon its back, 

 often deciduous in fruit, the lower persistent. Corolla 

 much exserted, dilated above into the throat, glabrous 

 within, upper lip arched, entire or emarginate, the lower 

 spreading or deflexed, its lateral lobes small and some- 

 what connected with the upper, its middle lobe broad, 

 sometimes emarginate, the margins mostly recurved. 

 Stamens 4. didynamous, ascending under the upper lip, 

 the upper pair somewhat shorter; anthers ciliate, the

 2-cleft at the apex; ovary deeply 4-parted. Nutlets 

 subglobose or depressed, papillose or tuberculate. 



1. S. tuberosa Benth. Perennial by tuberiferous rootstocks,

 high, rather sparsely leafy; leaves mostly ovate, truncate or cuneate 

 at the base, thin, coarsely and obtusely few-toothed or nearly entire, 

 1-4 cm. long, nearly all petioled; floral about equaling or longer than 

 the flowers; corolla narrow, about 15 mm. long, blue. 



Occasional in shady places in all the hills and in the chaparral 

 belt of the mountains. April-June.
