7. O. quercifolia, Pursh. (SMOOTH FALSE FOXGLOVE.) Smooth and

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

 woods ; common, especially southward. Aug. Corolla 2' long. 



8. O. integnrifolia. 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. ? integrifolia, Benth.) 

 Woods and barrens, Ohio to Illinois, and southward along the mountains. 

 Aug. Corolla 1' long. 



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

 3 high, very leafy) ; leaves ovate-lanceolate, pinnatifid, the lobes cut and toothed; 

 pedicels longer than the hairy calyx. Dry copses ; common. Aug. Corolla 1' 

 or more in length. 



$ 3. OTOPHYLLA, Benth. Calyx deeply 5-cleft, the lobes unequal : corolla pur-
