lanceolate acute.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 purple, 5" - 7" long. 



4. G. tenu.if.61ia, 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. setacea, Walt. Leaves bristle-shaped, as are the branchlets, 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 southward. 



2. DASYSTOMA, Raf. Calyx 5-deft, 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 pinnatifid 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 1^' long. 



7. G. quercifblia, 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. integrif 61ia, Gray. Smooth, not glaucous ; stem ( 1 - 2 high ) mostly 

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

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

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

 Corolla 1' long. 



9. G. grandifl6ra, 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 high, 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 5-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 (!' long). Low grounds, Penn. to Michigan, Illinois, and 

 southward.
