declinate style and stamina. Capsule globose, 

 partly 1-celfed, and imperfectly 4-valved. Seeds 

 2 or 3, umbilicate. 



An annual plant, with entire opposite and verticillated 

 leaves; peduncles axillary, l-fiowered, verticillate and op- 

 posite; flower particoloured. 



Species. 1. C venia. Hab. On the banks of the 

 Ohio, &.C. For an accurate figure. See Journal Acad. 

 Nat. Sc. Philad. vol. i. plate 9.— The only species hither- 

 to known to me. 



434. GERARDIA. L. 



Calix lialf 5-cleft, or 5-tootIied. Corolla sub- 

 campanulate, unequally o-lobed, segments most- 

 ly rounded. Capsule 2-celled, opening at the 

 summit. 



Certainly a confused and divided genus, the usual arti- 

 ficial character entirely excluding the North American 

 species which appear' to require a careful comparison 

 with Digitalis. — Herbaceous plants, very rarely shrubby; 

 leaves generally opposite, entire, or pinnatifid; flowers 

 solitary, axillary, opposite, approximating towards the 

 summits of the branches, yellow or purple. Capsule more 

 or less ovoid, not acuminate, 2-celled; dissepiment medi- 

 al, indivisible, parallel to and uniting with the simple 

 longitudinal margined receptacle. 



f Flo-uers purpte. ( Calix campanulate, margin 5-toothed.) 

 Species. 1. G. purpurea. Stem angular, much branch- 

 ed; leaves scabrous, linear, long and acute; flowers large, 

 subsessile; segments of the calix subulate. Hab. Com- 

 mon both in fresh and subsahne mai^hes. 2. * maritima. 

 Mr. Rafinesque, in the New York Medical Repository, 

 vol. ii. p. 361. Low and succulent; stem angular; leaves 

 linear, carnose, short, somewhat obtuse; flowering branch- 

 es partly naked; flowers small, shortly pedunculate, the 2 

 tipper lobes ciliate; margin of the calix crenulate. Hab. 

 Not unfreqtient in the salt-marshes of New .Jersey and 

 New York. Flowering from July to September. G. pur- 

 purea, /3. crassifolia. Ph. It is unquestionably distinct 

 from G. purpurea; being every way smaller; oppositely 

 branched from the base upwards; the leaves are also 

 ruite convexly carnose and shining; the flowers ot a pale 

 red, are remotely sit\iated, and seldom exceed 3 pair, ap- 

 proximating towards the summits of the branches; the 

 pubescent ciliation of the corolla and the truncature of
