 tary or in cymes of 3, 1 in. in diam. ; sepals ovate ; 

 petals striated and strap-shaped ; styles connate : cap- 

 sule oblong-ovoid, large. June, July. Found only in the 

 highest mountains of the Carolinas and Ga. G.F. 4:581.

 beries. 



11. filegans, Steph. A low perennial, 1-lK ft. high, 

 with erect, winged stem filled with black dots: Ivs. 

 ovate-lanceolate, rather clasping, bright green: fls. race- 

 mose, 1 in. in diam., appearing in late summer and au- 

 tumn; sepals ovate, much shorter than the petals, the

 3-nerved clasping Ivs. % in. or less long, the stems 4-an- 

 gled, 2-15 in. tall : fls. % in. across, yellow, with petals 

 equaling the linear-lanceolate sepals and bracts; styles 

 one-third the length of the ovary. Japan to India. — Per- 

 ennial ; but Hooker (Flora of India) says it is annual. 

 Blooms in spring. Not hardy North. 



DD. Plant higher, S^ ft. 

 E. Leaves linear. 



13. densiilbrum, Pursh (H. prolificiim, var. densifld- 

 rum, A. Gray). A shrub, closely related to IT. prolifi- 

 cum, but rarer: stems erect, stout, densely leafy, 4-6 

 ft. high: Ivs. variable, broader and oblong like those of 

 R. prolificum, or narrower and linear-lanceolate like 

 thoseof fl". galioides, 1-2 in. long, mucronulate: fls. ^in. 

 in diameter, in broad, dense, many-fld. cymes; sepals 

 narrow, not foliaceous; stamens distinct; styles connate: 

 capsule completely 3-celled, short and slender, longitu- 

 dinally furrowed. July-Sept. Pine barrens, N. J., and 

 south. Mn. 4:97. G.P. 3:527.-E.H. 1899, p. 517, 518. 

 Not well known, but appears to be hardy. 



14. galioides. Lam. {H. axiUHre, Lam., not Michx.). 

 Practically suff ruticose, but sometimes occurs as a round, 

 compact shrub : stems erect, 3 ft. high, slender : Ivs. 

 linear, mucronulate, dark green, crowded, 1-3 in. long: 

 fls. in dense, many-fld. cymes M-K in. wide ; sepals 

 linear, foliaceous, equal, shorter than the narrow petals ; 

 stamens distinct; styles at first connate, becoming free: 

 capsule conical, completely 3-celled, acute, longitudinally 

 furrowed. July-Sept. Natural to low, wet grounds, 

 Delaware to Pla., but grows freely in rich garden soil. 

 G.F. 10:433. G.C. III. 24:301. -Seems to be perfectly 

 hardy. Easily raised from seeds. Not well known. 



15. sphaerocdrpum, Michx. Erect perennial, 1-2J^ ft. 

 high, 4-sided: Ivs. linear or linear-oblong, obtuse, 1-2 

 in. long: cymes of many small fls. Vi in. in diameter, 

 nearly leafless ; sepals ovate, mucronate; petals 3 times 

 longer; stamens numerous, distinct; styles united be- 

 low : capsule globose, M in. long. July. Frequents 

 rocky banks of rivers, Ohio and Ky. ; satisfactory in 

 light.sandy soil. — Spreads rapidly by stoloniferous roots, 

 covering the soil and preventing washing. Not very 

 ornamental. Half-hardy North. 



EE. Lvs. broadly lanceolate or ovate: sepals ovate. 



p. Stamens and styles longer than the petals: 



styles divergent. 



16. hirclnum, Linn. Glabrous subshrub of round, 

 compact habit, 2-3 ft. high, the branches winged toward 

 the tips: lvs. ovate-lanceolate, acute, glandular, 1-2 in. 

 long, deep green : As.VA in. wide, solitary or 3-clustered ; 

 sepals deciduous, one-third to one-fourth the length of

the lance-oblong petals, which are of a deeper yellow 

 than in the other species; stamens very long; styles 

 spreading, longer than the stamens : capsule ovoid, 

 pointed. July-Aug.— Species characterized by the 

 strong, goat-like odor of the lvs. (hence the name). Of 

 easy cultivation, but requiring a dry position and winter 

 protection. Mediterranean region. Var. minus, Wats. 

 Dwarfer, with smaller lvs. and fls. ; as pretty and free- 

 blooming as the type, and, in the rock-garden, preferable. 



17. elitum, Dryand. Strong, tufted undershrub, re- 

 calling H. Androsmmum, 3-i ft. high, i ot quite hardy, 

 sometimes credited to the United States, but really from 

 the Canaries: lvs. oval, lK-3 in. long, dark green, whit- 

 ish below, acute: fls. numerous, 1 in. in diameter, in 

 3-7-flowered cymes; sepals ovate-oblong; stamens dis- 

 tinct; styles prolonged, distinct: capsule oblong, small. 

 July. 



18. noribiindum, Dryand. A subshrub, with round, 

 glabrous stems: lvs. lanceolate-elliptic, light green,with- 

 out dots, numerous, 1-1/^ in. long: fls. in few- to many- 

 flowered panicles, lJ^-2 in. in diameter, with dilated 

 peduncles: sepals somewhat acute ; stamens numerous, 

 shorter than the petals, petals and stamens persistent; 

 ovary oval; styles long, divergent, with capitate stig- 

 mas.— From the Canary and Madeira Islands. Not hardy 

 North, but in cultivation in S. California. Grows very 

 rapidly to the height of about 12 ft. Generally prop, 

 from seeds, which are produced freely. 



19. mnltifldrum, Hort., not HBK. A supposed hybrid 

 between H. Androsmmum and H. elatiim, assuming an 

 intermediate form, but more closely resembling ST. 

 elatum. It also resembles R. hircinum, but is more 

 shrubby and taller. Lvs. ovate-oblong, acute, somewhat 

 clasping, 1-2 in. long: fls. in profusion, several in a 

 cyme, 1 in, wide, lasting two weeks; sepals small, ovate 

 reflexed; styles spreading: capsule oblong. July.— Not 

 very hardy.

20. aiJreum, Bartram. Fig. 1118. Showy shrub 3 ft. 

 high, more woody than most species, of stiff, dense 

 habit, top often globular like a miniature tree, the 

 branches 2-edged, with thin, exfoliating red bark: lvs.
