1. T. tenella (Benth.) Heller. Branches almost filiform, 6 in. high; leaves 

 heteromorphic, the lowest rotund to ovate, entire or with deep notch 

 on each side near the apex, 2 to 4 lines long, on petioles longer than the 

 blade, the upper palmately 3-parted or -divided into oblong segments, the 

 middle Begmenl longesl ; bracts entire, shorter than the pedicels; pedicels 

 in 2b or 3s, ;is much as 1 in. long; corolla minute, little exceeding the calyx, 

 while or very pale blue, the lobes of some of them purple-dotted; capsule 

 exceeding the calyx; seeds 1 to each cell. — (T. collinsioides Nutt. Collinsia 

 tenella Benth.) 



Seemingly uncommon within our limits, but easily overlooked: Mt. Hamil-

6. SCROPHULARIA L. Figwort. 



Bank perennial herbs with opposite leaves. Flowers small, dull reddish, 

 cymose, the cymes disposed in a narrow terminal panicle. Calyx 5-parted 

 into broad rounded lobes. Corolla with a somewhat globular tube, the two 

 upper lobes longer than the two lateral, all erect except the short deflexed 

 lower one. Stamens with anthers 4, the fifth sterile and adnate to the tube 

 of the corolla, appearing like a scale under the upper lip. Capsule septicidal, 

 many-seeded. (Latin scrofulae, the plant a one-time remedy for scrofula.) 



1. S. calif ornica Cham. Tall, 3 to 6 ft. high, glabrous except the finely 

 glandular-pubescent inflorescence; leaves ovate, cordate at base, serrate or 

 incised-serrate; corolla about 4 lines long, with a nectar-disk at base of 

 flower. 



Common in moist places, mostly along gulches in the hills: Coast Eanges;

 the panicle with very flexuous branches and grows along rock outcroppings: 

 Pellejo Hills (Solano Co.) and elsewhere. 



7. PENTSTEMON Mitch. 

 Perennial herbs or suffrutescent plants of hilly districts. Leaves opposite, 

 the upper sessile. Flowers mostly showy, in racemes, panicles, or cymes. 

 Calyx 5-parted. Corolla tubular and often inflated, the limb either slightly 

 or strongly bilabiate; upper lip 2-lobed, the lower 3-cleft. Stamens with 

 anthers 4, declined at base, ascending above; fifth stamen represented by a 

 conspicuous sterile filament which is often dilated or bearded. Capsule sep- 

 ticidal (the valves cleft at apex through the persistent base of the style), 

 many-seeded. Seeds angled. (Greek pente, five, and stemon, stamen.) 



Anthers densely woolly; corolla red LP. newberryi. 



Anthers glabrous. 



oterile filament bearded.

 from a woody base; [eaves coriaceous, orbicular to round-ovate, about 7 lines 

 long, serrulate, rarely inclined to be entire; racemes sessile; sepals narrowly
