5. hirta, Swartz. Lvs. densely cespitose, with short, 

 scaly stalks which are brownish, like the rachides; 

 pinnae numerous, rather distant bipinnatifid, the segms. 

 with much incurved margins. The Ivs. are usually 

 6-15 in. long. Cape of Good Hope. Var. Ellisiana, 

 is more commonly cult. 



6. lanSsa, .Wats. (C. vestita, Swartz). Fig. 900. Lvs. 

 cespitose, with stalks 2-4 in. long, slightly hairy, as are 

 the segms., tripinnatifid, 4-10 in. long, 1-2^ in. wide, 

 the pinnae lanceolate-deltoid: indusia formed of the 

 ends of roundish or oblong lobes. Conn, to Kans. and 

 Ala. Hardy. 



7. Codperae, D. C. Eaton. Lvs. 3-8 in. long, bipin- 

 nate, the stalks covered with nearly white hairs, each 

 tipped with a gland; pinnules 



roundish ovate, crenate and in- 

 cised. Calif, to Mex. 



BB. Segms. bead-like, minute: in- 

 dusia usually continuous. 

 c. Lvs. hairy or woolly beneath, 



but not scaly. 

 D. Upper surface of segms. smooth. 



8. gracillima, D. C. Eaton. 

 LACE FERN. Lvs. cespitose, 1-4 

 in. long, borne on the nearly equal 

 dark brown stalks, bipinnate; 

 pinnae with about 9 pinnules, 



finally smooth above. Idaho to Calif. 

 Hardy 



9. Clevelandii, D. C. Eaton. Lvs. 4-8 in. 

 long, tripinnate, dark brown beneath, with 

 closely imbricate, ciliate scales, which grow 

 on both the segms. and the rachides; segms. 

 nearly round, the terminal larger. Calif. 



DD. Upper surface of segms. pubescent. 



10. tomentdsa, Link. Lvs. 8-15 in. long, on stalks 

 4-6 in. long, everywhere covered with brownish white 

 hairs, tripinnate; terminal segms. twice as large as the 

 lateral. Va. to Ariz. 



cc. Lvs. covered beneath with scales, but not woolly. 



11. Fendleri, Hook. Lvs. 3-6 in. long, borne on the 

 chaffy stalks, rising from tangled, creeping roptstocks, 

 tripinnate; rachis with broadly-ovate white-edged 

 scales, which overlap the subglobose segms. Texas, 

 and Colo, to Calif. 



ccc. Lvs. covered beneath with both scales and wool. 



12. myriophylla, Desv. (C. elegans, Desv.). Lvs. 

 densely cespitose from short, erect, scaly rootstocks, 

 3-9 in. long, borne on the chestnut-colored scaly stalks, 

 triquadripinnatifid; ultimate segms. minute, innumer- 

 able. Texas, Ariz, and Trop. Amer. 



A native species worthy of cult, is C. leucdpoda, Link, from 

 Texas, with broadly deltoid-ovate Ivs C. unduldta, Hope & 

 Wright. Dark green fronds, softly pubescent. China. G.C. III.

CHEIRANTHUS (derivation in dispute, but proba- 

 bly from Greek for hand and flower) . Crudferae. Flower- 

 garden perennials, with large purple, brown, orange 

 or yellow fragrant bloom. 



Leaves alternate, entire, on a 

 strict or upright st. : lateral 

 sepals sac-like at the base: valves 

 of the pod with a strong mid- 

 nerve. Much confounded with 

 Matthiola, and the genera are 

 not sufficiently distinct. In 

 Cheiranthus, the Ivs. are acute, 

 hairs 2-parted and appressed, 

 stigma more spreading, pod more 

 flattened and seeds not thin- 

 edged; and the fls. are prevail- 

 ingly orange or yellow Probably 

 a score of species, in the Canary 

 and Madeira Isls., Medit. region 

 and E. and in N. Amer. The 

 garden species are confused; a 

 critical study may find that some 

 of them belong to Erysimum or 

 other genera. The genus hybrid- 

 izes with Erysimum. 



Cheiri, Linn. WALLFLOWER. 

 Fig. 901. Perennial, slightly 

 pubescent, 1-2^ ft.: Ivs. lanceo- 

 late and entire, 

 acute: fls. large, 

 mostly in shades of 

 yellow, in long, ter- 

 minal racemes, 

 sweet - scented. S. 

 Eu. An old gar- 

 den favorite, bloom- 

 ing in spring. Al- 

 though a woody 

 perennial, it is best 

 to renew the plants 

 from seed, for they 

 begin to fail after 

 having bloomed one 

 or two years. Seed- 

 lings should bloom 

 the second year; 

 in England, Christ- 

 mas bloom is se- 

 cured from seeds 

 Cheiranthus Chain. sown in Feb. There 



are dwarf and dou-
