CLARKIA 



blooming freely in violet-colored heads, which scarcely 

 overtop the foliage. The plant makes an excellent per- 

 manent edging, and is worth growing for this purpose 

 alone. It is easily propagated by dividing the clumps; 

 but, like other tufted plants, it profits by having the 

 stools broken up and replanted every few years. Itrarely 

 seeds. It thrives in any garden soil. The leaves may be 

 cut freely, for they quickly grow again. l 2_ g. 



CLADANTHITS (Greek, klados, branch, and anthos, 

 flower ; alluding to the branching, which distinguishes 

 this monotypic genus from Anthemis). Compdsitae. An 

 annual, yellow-rayed herb, branched from the base in a 

 forking manner. A flower terminates each branch, where- 

 upon two new branches start from directly beneath the 

 flower. Each of these is temporarily stopped by a flower, 

 and so on. A free-flowering, hardy annual, requiring no 

 special care.

 glabrous, 2-3K ft. high : Ivs. alternate, pinnately parted ; 

 lobes linear, trifld: fls. solitary, bracted. N. Africa, not

CLADOTHAMNUS {klados, branch, and thamnos, 

 bush, from the Greek), JilricAcew. Erect shrubs, with 

 many virgate branches : Ivs. deciduous, alternate, entire : 

 fls. pink, terminal, 1-3, nodding ; corolla divided to the 

 base or nearly so into 5 oblong petals ; stamens 10 ; cap- 

 sule 5-6-celled, Two species in Pacific N. America, from 

 Alaska to Washington. Hardy deciduous shrubs, with 

 handsome, rather large, pink fls. in summer; rarely cul- 

 tivated. They will probably grow best in peaty and sandy 

 soil, in a half-shady position ; prop, by seeds or by 

 cuttings of soft wood under glass, and by layers.

 gardens. Legumindsce. Deciduous trees: lvs. alternate, 

 odd-pinnate, with few, rather large, entire, short-stalked 

 leaflets : fls. in long, often panicled racemes, white, papil- 

 ionaceous ; calyx campanulate, 5-toothed ; stamens 10, 

 free or connate only at the base : pod linear, compressed, 

 with 3-6 seeds. Two species in N. Amer. and E. Asia. 

 Hardy ornamental trees of medium size, with showy fls, 

 and handsome foliage, turning bright yellow in fall. They 

 thrive in almost any soil. Prop, by seeds, sown in spring, 

 or by root cuttings, dug up in fall and kept in sand or 

 moss, moderately moist and cool, until spring. 



tinctdria, Raf. (C. lutea, Koch. Virgilia lutea, Michx.), 

 Tree, with yellow wood and smooth bark, sometimes 50 ft. : 

 leaflets 7-9, oval or ovate, glabrous, bright green, 3-4 in. 

 long: panicles loose, drooping, 10-20 in. long: fls. white, 

 fragrant, over 1 iu. long. June. Kentucky, Tennessee 

 and N. Carolina. B. 8.3:119-20. Mich. Hist. Arb. III. 266. 

 Gng. 2:401; 5:98. F.E.8:427. G.P. 1: 92.-One of the 

 most beautiful flowering native trees, with wide, graceful 

 head and a short trunk, well adapted as single tree on 

 the lawn. Hardy north to NewEng. and Ont. The wood 

 yields a clear yellow dye. Known as Yellow-wood. 



Amur^nais, Koch (MadcMa Amur4nsis,BuTpv.). Tree, 

 to 40 ft. : leaflets 7-11, elliptic- or oblong-ovate, rounded 

 at the base, glabrous, 2-3 in. long: racemes erect, dense- 

 fid., often panicled at the base, 4-8 in. long: fls. whitish,

CLABEIA (Captain Wm. Clark, companion of Lewis, 

 explorer of the Kocky Mt. region). Onagr&cew. Herbs 

 of western N. Amer., with alternate, mostly entire lvs. 

 and showy fls. in the upper axils or in terminal racemes. 

 Pis. regular, the calyx tubular, the petals 4, narrow at 

 the base and entire or lobed, wide-spreading ; stamens 

 8, the alternate ones shorter; stigmas 4, large : pod ob- 

 long or linear, 4-sided. Clarkias are hardy annuals of 

 easy cult. They thrive in a warm, light soil, either fully 

 exposed to the sun or in partial shade. Useful for low 

 masses or for edgings ; also for vases and baskets. 

 They have been much improved by domestication.
