782 SCROPHULARIACEAE 



glandular-pilose. Leaf -blades oblong-linear, obtuse, entire, 1.5-2.5 cm. long, minutely pubescent 

 or glabrous, attenuate to sessile or slightly petioled bases; inflorescence lax, the lowest bracts 

 foliose, the others subulate and much shorter than the pedicels which become 5-10 mm. long 

 and tend to reflex in fruit; corolla 4-5 mm. long, glabrous throughout, basal pouch rounded, 

 the tube and upper lip white with violet lines, the latter with lobes erect and proximally medianly 

 yellowish with dark markings, the lower lip longer, violet-blue, its lateral lobes much exceeding 

 the lowermost lobe ; capsule 3 mm. long ; seeds 1 to a cell, 2 mm. long, oblong, turgid. 



Granitic sand, Canadian Zone to Arctic-Alpine Zone; mountains, from Siskiyou County, northern California, 

 south on the Sierra Nevada and adjacent ranges of western Nevada to the San Bernardino and San Gabriel 

 Mountains of southern California. Type locality: Greenhorn Mountains, Kern County, California. June-Aug. 



12. TONELLA Nutt. ex A. Gray, Proc. Amer. Acad. 7: 378. 1868. 



Erect annual herbs. Leaves opposite, the lower or all tripartite. Flowers solitary or 

 fascicled, axillary to the upper somewhat reduced leaves. Sepals 5, lanceolate, united over 

 one-third their length. Corolla nearly rotate, glabrous, the five lobes obtuse or rounded, 

 distally violet, proximally white and conspicuously marked with broken madder-violet 

 lines. Stamens 4, equal and exserted, the filaments pubescent, the anthers glabrous with 

 explanate cells. Capsule globose-ovoid, primarily septicidal, but eventually also loculi- 

 cidal. Seeds maturing 1 or 2 to a cell, large, turgid, wingless. [Meaning unknown.] 



Two species, of western North America. Type species, Tonella collinsioides Nutt. 



Corolla 5-7 mm. wide, its distal violet portion smaller than the white proximal portion, which bears on the upper 

 lobes conspicuous madder-violet radii, the upper longer than the lower lobes; sepals, pedicels, and stems 

 distally glandular-pilose; flowers fascicled; plants mostly 2-3.5 dm. tall. 1. T. floribunda. 



Corolla 2-2. S mm. wide, its distal violet portion longer than the white and slightly marked proximal portion, the 

 lower longer than the upper lobes, the lowermost lobe longest; sepals ciliate with glandless hairs; pedicels 

 1 or 2, distally finely glandular-pubescent; stems glabrous throughout; plants 1-2.5 dm. tall, very lax. 



2. T. tenella. 



1. Tonella floribunda A. Gray. Large-flowered Tonella. Fig. 4753. 



Tonella floribunda A. Gray, Bot. Calif. 1 : 556. 1876. 

 Collinsia floribunda Greene, Pittonia 1: 55. 1887. 



Plant 2-3.5 dm. tall, erect, the stem, pedicels, and calyces finely glandular-pilose. Leaf- 

 blades 2-5 cm. long, with segments lanceolate, the lateral lobes usually little shorter than the 

 median blade, the lower leaves (with blades shorter and wider) usually lost by anthesis; upper 

 axils floriferous, the linear bracts reduced toward stem-apex, each subtending 2 or 3 flowers, 

 of which the pedicels become 10-20 mm. long; calyx 4 mm. long, its sepals united 1.5 mm., 

 their free portions acute; corolla 5-7 mm. long, its distal violet portion smaller than the pale 

 and conspicuously marked proximal portion, the upper larger than the lower lobes ; capsule 

 3 mm. long; seeds 2 to a cell, 1.5 mm. long. 



Loam banks, in canyons. Upper Sonoran Zone; along Snake River and tributaries in southeastern Washiiig- 

 ton, northeastern Oregon, and western Idaho. Type locality: Clearwater (Kooskooskie) River, Idaho. April- 

 May.

Tonella tenella Heller, Muhlenbergia 1 : 5. 1900. 



Plant 1-3 dm. tall, laxly ascending, the stem and pedicels glabrous, or minutely pubescent 

 above nodes. Leaf-blades 1-1.5 cm. long, pilose on upper surface, with segments lance-oblong 

 to oblong, the lateral lobes shorter than the median blade, the lower leaves (with blades 

 shorter and wider, trilobed to entire) usually retained until anthesis; most axils florifet^ous, 

 the lanceolate bracts foliose, each subtending 1 (or sometimes 2) flowers, of which the pedicels 

 become 8-15 mm. long; calyx 2 mm. long, its sepals united 1 mm., their free portions acute to 

 obtuse, ciliolate; corolla 2-2.5 mm. long, its distally violet portion longer than the white and 

 slightly marked proximal portion, the upper smaller than the lower lobes ; capsule 2-2 . 5 mm. 

 long; seeds 1 to a cell, 1.5 mm. long. 



Moist rocky soil, especially among scrub oaks. Upper Sonoran and Transition Zones; Pacific coastal region, 

 southwestern Washington to central California. March-May. 



13. GALVEZIA Dombey ex. Juss. Gen. 119. 1789. 



Erect or diffuse herbs or shrubs, with entire opposite or ternate leaves. Flowers axil- 

 lary, forming a terminal raceme. Bracteoles none. Sepals 5, the lower pair shorter. Co- 

 rolla tubular, red, externally pubescent, saccate at base beneath, strongly 2-lipped, the 

 lower lip with a shallow 2-ridged palate. Stamens 4, didynamous, glabrous, the yellow 

 anthers at orifice of corolla-tube. Stigmas united, punctiform. Capsule globose-ovoid, 

 hirsute-pubescent, its cells unequal, the dorsal rounded at base and distally with two lateral 

 ruptures, the ventral narrowed at base and distally with one large rupture. Seeds cylindric, 

 with many thin wings. [Named in honor of Jose Galvez, a Spanish administrator.] 



Species less than 10, in Lower California and on islands off the coast of southern California, and on the 

 coast of Peru and Ecuador. Type species, Galvezia fruticosa J. F. Gmelin.
