and usually with 2 bractlets at the base of the calyx. Flowering all summer ; 

 in wet or damp places. (Name from gratia, grace or favor, from supposed 

 medicinal properties.) 



1. Anthers with a broad connective, the cells transverse ; stems mostly diffusely 

 branched, or creeping at base, soft viscid-pubescent or smooth; corollas 

 0.8-1.5 cm. long ; bractlets foliaceous, equaling the calyx. 



* Sterile filaments minute or none; corolla whitish, with the tube yellowish. 



1. G. virginiana L. Stem clammy-puberulent above, 1-3 dm. high ; leaves 

 lanceolate, with narrow base, acute, entire or sparingly toothed ; peduncles almo.it 

 equaling the leaves (1-2.5 cm. long); pod ovoid, 4-5 mm. long. Wet or muddy 

 places, local, centr. Me. and w. Que., westw. and southw. June-Aug. 



2. G. sphaerocarpa Ell. Smooth, rather stout, 1.5-4 dm. high ; leaves lance- 

 ovate or oblong to oval-obovate, 2-5 cm. long, toothed ; peduncles scarcely longer 

 than the calyx and the large globular pod (6 mm. in diameter). Wet places, 

 N. J. to Mo., and southw. Apr.-June. 



** Sterile filaments slender, tipped with a little head; leaves short (1-2.6 cm. 



long}. 



3. G. visc6sa Schwein. Clammy-pubescent or glandular; leaves ovate-lance-

 simple stems.

16. DIGITALIS [Tourn.] L. FOXGLOVE 



Calyx 5-parted ; the lobes often foliaceous. Corolla with a somewhat in- 

 flated tube and short scarcely spreading limb, declined. Stamens 4, didynamous, 

 included in the corolla. Tall herbs, with alternate or scattered entire or toothed 

 leaves and showy racemose flowers. (Digitalis, of or belonging to the finger, 

 as the fingers of a glove, which the tubular corollas have been thought to 

 resemble. ) 



1. D. PCRPtiREA L. Stoutish pubescent biennial; corolla purple to white, 

 spotted, 4-5 cm. long. Meadows and pastures, Cape Breton I. ; also N. Y. ; 

 rather rare and local, a casual escape from gardens. (Introd. from Eu.)

The lateral lobes of the corolla or the lowest one commonly narrower than

 anther-cells confluent at the apex. Style entire ; stigma single. Capsule flat- 

 tened, obtuse or notched at the apex, 2-celled, few-mauy-seeded. Chiefly 

 herbs ; flowers blue, flesh-color, or white. (Derivation doubtful ; perhaps the
