CENOTHERA 



332. Very variable. Var. Youngii ((E. Youngii, Hort.) 

 is common in cultivation, and is prized for its stocky 

 growth and profusion of bloom. It is a strong, larger- 

 leaved plant, with firm, shiny, slightly glaucous foliage, 

 and bearing many bright lemon-yellow flowers: 2 ft., 

 much branched and somewhat decumbent at base. Ex- 

 cellent. Var. major, Hort., is a strong-growing florifer- 

 ous form, forming a dense bush-like specimen. 



12. linearis, Michx. ((E. fruticbsa, var. linearis, Wats. 

 (E. riparia, Nutt.). Usually lower and more slender: 

 Ivs. linear to narrow-lanceolate: capsule mostly less 

 broadly winged, clavate. Conn., south. Gn. 26, p. 481. 



13. pumila, Linn. Slender, erect biennial: Ivs. ob- 

 lanceolate or oblong, usually glabrous, entire, the radi- 

 cal spatulate : fls. an inch or less across in a loose, leafy 

 spike or raceme, the calyx-tube shorter than the ovary, 

 the petals obcordate: capsule mostly clavate, short- 

 stalked or sessile. Nova Scotia, south. 



IX. SUBGENUS HARTMANNIA (including Xylopleurum, 



etc.). Stem -b earing : stigma 4-lobed: calyx-tube 

 funnel form, often very long: capsule club- shaped 

 or oborate, broad-winged: fls. white, pink or red, 

 diurnal. 



A. Plant canescent or villous, usually erect, or at least 

 prominently ascending. 



14. specidsa, Nutt, Perennial, with a rootstock, erect 

 or ascending branches, 2 ft. or less high, canescent: 

 Ivs. linear to lance-oblong, 4 in. or less long, remotely 

 or sinuately dentate, or the lower ones pinnatifid, at- 

 tenuate at base: calyx -tube as long as the ovary; pet- 

 als large, obcordate, white : capsule %-% in. long, 

 8-winged, acute at top. Mo., W. and S. B.M. 3189. Gn. 

 26, p. 482. 



15. tetraptera, Cav. Villous : capsule larger and 

 more broadly winged, very abruptly contracted at top: 

 calyx-tube shorter than the ovary: 'fls. white, becoming 

 rose. Texas, south. B.M. 468. Var. Childsii ( (E. rb- 

 sea Mexicana, Hort.) is a handsome form introduced 

 from Texas by John Lewis Childs in 1892. It was found 

 in the wild. "We first secured the pink," Mr. Childs 

 writes, "and afterwards someone else sent us the white, 

 blush and the other shades, all from Texas." In some 

 respects it differs markedly from (E. tetraptera, and it 

 is not impossible that it is a distinct species. In culti- 

 vation it is a trailing plant. The Ivs. tend to be broader 

 and less pointed than in (E. tetraptera. It does not pro- 

 duce seed in the North, but is readily propagated by 

 cuttings. It is an excellent plant either for the flower 

 garden or for pots in the conservatory. It is popularly 

 known as the "Mexican Evening Primrose." 



16. rdsea, Ait. Koot biennial or perennial : stem 

 erect or ascending, 1-2 ft., branching from the base: 

 Ivs. lanceolate to narrow ovate-lanceolate, mostly acumi- 

 nate, rather abruptly narrowed to a petiole, entire or re- 

 motely denticulate or the larger ones small-lobed at the 

 base: calyx -tube shorter than the ovary: fls. small, 

 fuchsia-like, purple or rose, the petals rounded and en- 

 tire: capsule like that of (E. speciosa. Texas and New 

 Mexico, south. B.M. 347. Offered by seedsmen. 



AA. Plant glabrous or essentially so, nearly stemless 

 or else prostrate. 



17. acaulis, Cav. ((E. taraxacifdlia, Hort.). Tufted 

 perennial or biennial plant, at first stemless, but pro- 

 ducing prostrate, somewhat zigzag stems: Ivs. oblong 

 in outline, 5-8 in. long, petioled, divided into many un- 

 equal narrow divisions (like a dandelion leaf) : fls. usu- 

 ally opening white, but changing to rose, large (2-3 in. 

 across ) , the very slender tube 3-5 in. long : capsule short- 

 obovate, broadly triangular-winged above. Chile. B.R. 

 9:763. Gn. 26, p. 480. -A very interesting plant. 



X. SUBGENUS PACHYLOPHUS. Stemless or essentially 



so: stigma 4-cleft: calyx-tube very slender but 

 enlarging upwards, longer than the ovary: cap- 

 sule with wrinkled or contorted wings: fls. white 

 or pink. 



18. csespitdsa, Nutt. ((E. ex{mia,Gr&y. (E.margi- 

 nata, Nutt.). Crown 24 in. high, perennial or biennial: 

 Ivs. clustered, oblong to narrow-lanceolate or spatulate,

sometimes 1 ft. long, attenuate, repand-toothed, pubes- 

 cent: fls. white or pink, 1^-3 in. across, the petals ob- 

 cordate; calyx-tube 2-6 in. long: capsule oblong-pointed, 

 1-2 in. long. Neb., west and south. B.M. 1593 5828 

 Gn. 26:469; 47, p. 46. 



XI. SUBGENUS LAVAUXIA. Stemless or essentially so: 

 calyx-tube very slender, enlarging upwards, 

 longer than the ovary: capsule with plane or 

 entire wings: fls. white, pink, or even pale yel- 

 low. 



19. brachycarpa, Gray. Perennial, densely pubescent: 

 Ivs. thickish, ovate to very narrow-lanceolate, about 6 in. 

 long, long-stalked, entire or notched or lyrately pin- 

 natifid: calyx-tube 2-3 in. long; petals about 1> in. 

 long, purplish: capsule ovate, often 1 in. long, the 

 wings not wrinkled. Kansas, west and south. 



1516. Godetia amcena. 

 G. rubicunda splendens of the trade (X %). 



XII. SUBGENUS GODETIA. Stem-bearing : calyx-tube 

 short and usually broad: capsule ovate or lin- 

 ear, 4-sided, not winged: fls. lilac, purple or 

 rose, showy. 



The Godetias are very showy garden annuals, with 

 brilliant pink or red-purple flowers of satiny luster. 

 They are generally of easy culture in any warm garden 

 spot, although sometimes subject to what appears to be 

 a disease of the root. They are excellent subjects for 

 pot culture, either under glass or in the open. The gar- 

 den forms are derived from two species.
