lanceolate aatte teeth nearly as long as the tube ; corolla larger than in No. 1 . — 

 Damp grounds, Illinois, Wisconsin, and westward. 



* * Peduncles long and filiform, commonly exceeding the leaves: stems diffusely 

 branched, slender (8' -20' high) : corolla light purjile, 5" -7" long. 



4. G. teiiuif61ia, Vahl. (Slender G.) Leaves narrowly linear, acute, 

 the floral ones mostly like the others; calyx-teeth very short, acute; pod globular, 

 not exceeding the calyx. — Dry woods : common. 



5. G. set&cea, Walt. Leaves bristle-shaped, as are the hranchlets, or the 

 lower linear ; pod ovate, mostly longer than the calyx, which has short setaceous teeth. 

 (G. Skinneriana, Wood.) — Dry grounds, Penn. to Wisconsin, and^jQuthward. 



§ 2. DASYSTOMA, Raf. Calyx h-cleft, the lobes often toothed: corolla yellow; 

 the tube elongated, woolly inside, as well as the anthers and filaments : anthers all 

 alike, scarcely included, the cells awn-pointed at the base: leaves rather large, all 

 of them or only the lower pinnutifid or toothed. (Perennials.) 



6. G. flava, L. partly. (Downy False Foxglove.) Pubescent with a 

 fine close down ; stem (3° -4° high) mostly simple; leaves ovate-lanceolate or ob- 

 long, obtuse, entire, or the lower usually sinuate-toothed or pinnatifid ; peduncles very 

 short ; calyx-lobes oblong, obtuse, rather shorter than the tube. — Open woods, 

 especially in the Middle States. — Corolla l£' long. 



7. G. quercif61ia, Pursh. (Smooth False Foxglove.) Smooth and 

 glaucous (3° - 6° high), usually branching ; lower leaves commonly twice-pinnatifid ; 

 the upper oblong-lanceolate, pinnatifid or entire,; peduncles nearly as long as the calyx, 

 the lance-linear acute lobes of which are as long as the at length inflated tube. 



— Rich woods, especially southward. — Corolla 2' long. 



8. G. integrif61ia, Gray. Smooth, not glaucous; stem (l°-2° high) mostly 

 simple ; leaves lanceolate, acute, entire, or the lowest obscurely toothed ; peduncles 

 shorter than the calyx. (Dasystoma quercifolia, var. 1 integrifolia, Benth.) — Woods 

 and barrens, Pennsylvania to Illinois, and southward along the mountains. — 

 Corolla 1 ' long. 



9. G. grandiflbra, Benth. Minutely downy; stem much branched (3°- 

 4° high) ; leaves ovate-lanceolate, coarsely toothed or cut, the lower pinnatifid; pedun- 

 cles rather shorter than the calyx; corolla (2' long) 4 times the length of the 

 broadly lanceolate entire or toothed calyx-lobes. (Dasystoma Drummondii, 

 Benth.) — Oak openings, Wisconsin (Lapham), Illinois (Vasey) and southward. 



— Intermediate between G. flava and the next. 



10. G. pedicularia, L. Smoothish or pubescent, much branched (2°- 

 3°- hi<rh, very leafy) ; leaves ovate-lanceolate, pinnatifid, and the lobes cut and toothed; 

 peduncles longer than the hairy mostly serrate calyx-lobes., — Dry copses : common. 



§ 3. OTOPHYLLA, Benth. Calyx deeply b-cleft, the lobes unequal: corolla pur- 

 ple (rarely white), sparingly hairy inside, as well as the very unequal stamens: 

 anthers pointless, those of the shorter pair much smaller. (Annuals?) 



11. G. auriculata, Michx. Rough-hairy ; stem erect, nearly simple (9' - 

 20' high) ; leaves lanceolate or ovate-lanceolate, sessile, the lower entire, the 

 others with an oblong-lanceolate lobe on each side at the base ; flowers nearly 

 sessile in the axils (1' long). — Low grounds, Penn. to Michigan, Illinois, and 

 southward.
