 BILL. Fig. 1630. The common American species, about 

 1J^ ft. high: st. angular: basal Ivs. long-petioled, 

 deeply 3-5-parted; st.-lvs. opposite, shorter-petioled:

 Amer. B.B. 2:341. S. 332. Showy native species; 

 should be more in cult. Grows best in somewhat wet 

 places. Var. plenum, a double-fld. variety of deeper 

 color. Var. album, a pale-fld. or pure white form is 

 known. 



17. incisum, Nutt. (G. eridnthum, Lind.). About 1 ft. 

 high, leafy branched, the st. thickened below, solitary: 

 Ivs. finely cut, long hairy, the hairs fine and silky: pedi- 

 cels conspicuously glandular-pubescent; sepals oblong- 

 lanceolate, mucronate; petals with stiff white hairs, 

 inner surface purple, about 1 in. wide. Ore. A hardy 

 species well worth growing. Not perfectly hardy near 

 Boston.

 erect, slender, grooved, from an almost woody base: 

 Ivs. kidney-shaped, 5-lobed, sometimes palmately so, 

 the lobes ovate, toothed, the teeth slightly mucronate:

 Summer. Pyrenees. Among the best for the border, 

 and useful for cutting. 



23. Wallichianum, D. Don. Of prostrate trailing 

 habit: st. and Ivs. covered with silky hairs, the st. 

 deeply grooved : Ivs. light green, 3-5-parted, with deeply

 summer; sepals 3-nerved, the lateral nerves stiff-hairy; 

 petals about twice as long as the sepals, smooth, 

 emarginate. Himalayas. B.M. 2377. S. 90. For the 

 rockery and must not be grown in the open exposed 

 parts of it. The hot dry winds of midsummer in E. U. 

 S. are not favorable. 



24. collinum, Steph. (G. Londesii, Fisch.). St. 

 angular and usually decumbent, grooved and hairy: 

 Ivs. palmately 5-parted, deeply divided and cut: 

 sepals lanceolate-ovate, 3-neryed, densely hairy;

 July. E. Eu. One of the showiest in its season. Should 

 be cut back before seeding, to induce second bloom. 



25. Grevilleanum, Wall. St. creeping, rarely a little 

 erect: Ivs. long-petioled, the blades usually 5-lobed,

 across; sepals oblong-ovate; petals obovate, some- 

 times hairy at their bases, pale rose or in some forma 

 with large purple spots, at least as to the wild plant, 

 1-2 times the length of the sepals. Himalayas. Useful 

 for the rockery.

GERANIUM, FEATHER: Chenopodium Botrys. 



GERARDIA (after John Gerarde, 1545-1607, per- 

 haps the most popular of the herbalists). Scrophulari- 

 acex. Hardy annual and perennial herbs, all American, 

 and mostly of the Atlantic states, with yellow or rosy 

 purple flowers, in late summer and autumn, the later 

 color rarely varying to white. 



Leaves mainly opposite: calyx 5-toothed or cleft; 

 corolla bell- to funnel-shaped, broad-throated, 5-parted, 

 the 2 posterior lobes often smaller and more united; 

 stamens commonly more or less hairy; anthers more or 

 less approximate in pairs: caps, globose, 2-grooved; 

 seeds usually angled, loose-coated. The first 3 species 

 described below belong to a section in which the roots 

 are more or less saprophytic; by some, and probably 

 correctly, they are considered as belonging to the 

 genus Dasystoma. These plants are therefore rather 

 difficult to cultivate, and are offered only by collectors. 

 G. tenuifolia is offered by one dealer, the seeds presuma- 

 bly gathered in European gardens. 



A. Fls. yellow. 

 B. Corolla pubescent outside: biennial or annual. 



Pedicularia, Linn. St. much branched: pubescence 

 partly glandular and viscid, especially on the pedicels 

 and calyx, while in the next 2 species there is no glandu- 

 lar pubescence: Ivs. 1-2 in. long, all pinnatifid: fls. in 

 loose panicles or solitary, the calyx-lobes oblong and 

 herbaceous, usually incised. E. N. Amer. 



BB. Corolla glabrous outside: perennial. 

 c. Height 8-6 ft. 



virginica, Linn. (G. quercifdlia, Pursh). St. at first 

 glaucous, sparingly branched : lower Ivs. 35 in. long, 

 1-2-pinnatifid; upper Ivs. rarely entire: calyx-lobes 

 ovate, entire. Dry woods, E. U. S. 



cc. Height 1-2 ft. 



lasvigata, Raf. Not glaucous but glabrous, the st. 

 simple or slightly branched: Ivs. 1^-4 in. long, entire, 

 or the lowest somewhat incised, all petioled, lanceolate 

 or ovate-lanceolate : calyx-lobes ovate-lanceolate, equal- 

 ing or shorter than the tube and caps, glabrous, about 

 twice as long as the calyx. Oak barrens, etc. S. E.
