 terminal clusters ; calyx 5-6 mm. long ; corolla 2-lipped, white varying to pale blue or pink, the 

 upper 3 lobes with a well-marked white and red pattern, the 2 lower unmarked or one of them 

 sometimes slightly so, tube 8-10 mm. long, the lobes nearly as long, oblong, subentire to shallowly 

 3-toothed, retuse or sometimes rounded at apex ; stamens and style exserted beyond the corolla- 

 lobes. 



Gravelly or sandy soils, Sonoran Zones; Inner Coast Ranges, Fresno County, and southern Sierra Nevada, 

 Kern County, south to the desert slopes of the San Gabriel Mountains, east through Inyo County and Mojaye 

 Desert, California, to Nevada, Arizona, and Sonora. Type locality: Independence, Inyo County, California.

9. LOESELIA L. Sp. PI. 628. 1753. 



Low subshrub or herbaceous perennial, with a woody taproot, ours 10-40 cm. high. 

 Leaves in ours alternate, linear, entire, or sometimes pinnately dissected into a few linear 

 lobes. Flowers solitary in the upper axils or aggregated into glomerules at the ends of 

 the upper branches. Flowers irregular. Corolla somewhat 2-lipped, stamens long-exserted, 

 declined. Capsule cylindric, exceeding or subequaling the calyx. [Named in honor of 

 Johannes Loeselius, Professor of Botany at Konigsberg.] 



A genus of about 16 species, natives of North and South America. Type species, Loeselia ciliata L.

 Cilia tenuifolia A. Gray, Syn. Fl. N. Amer. ed. 2. 2^: 411. 1886. 



Perennial with a woody taproot, stems much-branched from the base ; plant 10-20 cm. high ; 

 herbage glabrous to sparingly pilose below, minutely glandular above. Leaves alternate, linear, 

 entire or some pinnately dissected into few linear lobes ; flowers solitary in the axils of the upper 

 leaves ; pedicels 2-10 mm. long, glandular ; calyx cylindrical, glandular, membranous to the base 

 below the sinuses, lobes linear, one-half as long as the tube ; corolla red, 2-3 cm. long, 5 times the 

 length of calyx, tubular-funnelform, the lobes unequal and unequally cleft (giving a bilabiate 

 appearance), oblong-cuneate with a denticulate truncate apex; stamens unequal and unequally 

 inserted on the tube of the corolla but equally exserted from it ; style long-filiform, exserted, 

 3-cleft at the apex. 



Desert slopes, Sonoran Zones; southeastern San Diego County, California, south to Lower California and 

 east to Arizona and Mexico. Type locality: northern borders of Lower California, Tantillas Mountains, especially 

 at the entrance of the Great Caiion. May-Oct. 



10. LEPTODACTYLON Hook. & Arn. Bot. Beechey 369. 1838. 



Shrubs or subshrubs of straggly or compact habit, 1-20 dm. high. Leaves opposite or 

 alternate or sometimes differing on the lower and the upper part of the plant, digitately 

 or pinnately parted into linear, pungently acicular lobes, usually glandular and rarely 

 arachnoid-pubescent, usually with others densely fascicled in axils. Flowers congested in 

 cymes or glomerules at the ends of the branches, rarely solitary in leaf-axils, sessile or 

 subsessile. Calyx-lobes entire, equal or unequal, pungent, the sinuses about two-thirds 

 filled with a membrane forming a pseudotube. Corolla salverform or narrowly funnel- 

 form, usually conspicuous or showy, white to cream, yellow, lilac or pink, sometimes 

 sordid, the tube and throat imperceptibly continuous or the throat very narrowly expand- 

 ing ; lobes rotate to subrotately spreading. Stamens inserted in the tube or on the throat, 

 included, filaments subequaling anthers. Pistil included ; stigma 3-4-lobed. Capsule sub- 

 cylindric to cylindric, 3-4-celled ; locules several to many-seeded. [Name Greek, meaning 

 scales and fingers, in allusion to the shape of the leaves.] 



A genus of about 6 species, native of western North America. Type species, Leptodactylon californicum 

 Hook. & Arn. 



Corolla salverform, tube equal or shorter than the lobes; stamens inserted on the corolla-tube; shrub 2-15 dm. 



high. 1. L. californicum. 



Corolla narrowly funnelform, tube and throat longer than the lobes; stamens inserted high in throat; subshrub 

 1-S dm. high. 

 Leaves unequally 3-S-digitate from the base, chiefly alternate, sometimes differing in position on the lower 

 and upper parts of plant, flowers typically 5-merous; stigmas 3. 2. L. pungens.

Erect or decumbent evergreen shrub, sometimes quite straggly ; stems 2-20 dm. high, branch- 

 ing from base or somewhat virgate, densely clothed with the current season's leaves as well as 

 the dried leaves of one or more seasons back. Leaves evergreen, alternate to subopposite, pal- 

 mately 3-9-cleft into unequal, linear, acerose, pungent lobes with others densely fascicled in their 

 axils; lobes 3-12 mm. long, tomentose to glandular-hirsute; flowers sessile, solitary in the upper
