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. It rarely 

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

 cut freely, for they quickly grow again. l H. B. 



CLADANTHTJS (Greek, Iclados, branch, and anthos, 

 flower ; alluding to the branching, which distinguishes 

 this monotypic genus from Anthemis). Comp6sitie. 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. 



prolllerus, DC. [Antliemis Ardbica, Linn.). Annual: 

 glabrous, 2-3 >^ ft. high ; Ivs. alternate, pinnately parted ; 

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

CLADOTHAMNUS (klados, branch, and thamnn.i, 

 bush, from the Greek). Uric&ceir. 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.

 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. 



tinotdria, Raf. ((7. Ihtea, Koch. Virgilia littea, Mlchx.).

 Gng. 2:401; 5:98. F.E.8:427. G.F. 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 New Eng. and Ont. The wood 

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



Ainur6nsis, Koch {Madckia Amiirhisis, Rupr.). Tree,
