46 DIDYNAMIA. ANGTOSPEllMIA. 



(leclinate Style and stamina. Capsule globose, 

 partly 1 -celled, and imperfectly 4-valved. Seeds ^ 

 a or 3, umbilicate. 



An annual plant, with entire opposite and verticillated 

 leaves; peduncles axillary, 1-flowered, verticillate and op- 

 posite; flower particoloured. 



Species. 1. C. verna. IIab. 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. GERARDTA. L. 



Calix half 5-cleft, or 5-tootljed. Corolla siib- 

 campanulate, unequally 5-lobed, segments nios-i- 

 \y rounded. Capsule 2-cclled, opening at the 

 summit. 



Certainly a confused and divided genus, the usual arti- 

 ficial character entirely excluding the North \merican 

 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. 

 \Floivers purple. ( Calix campamtlaie, margin S-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 subsaline marshes. 2. * maritima, 

 Mr. Rafinesque, in the New York Medical Repositorj-, 

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

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

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

 upper lobes clliate; margin of the calix crenulate. Hab. 

 Not unfrequent in the salt-marshes of New Jersey and 

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

 purea, l3. crassifolia. Ph. It is unquestionably distinct 

 from G. purpurea; beuig every way smaller; oppositely 

 branched from the base upwards; the leaves are also 

 quite convexly carnose and shining; the flowers of a pale 

 red, are remotely situated, and seldom exceed 3 pair^ ap- 

 proximating towards the summits of the branches; the 

 pubescent ciliation of the corolla and the truncatare of
