D1DYNAMIA AXG10SPERMIA 365 



unequally 5-Iobed, lobes mostly rounded. Anthers more or less villose. 

 Capsule globose, or ovoid, 2-celled, opening at the apex. 



Herbaceous, or rarely suffruticose: leaves mostly opposite, entire, or pinnatifk! ; 

 flowers axillary, solitary. Nat. Ord. 211. LindL Scrophulaiusejb. 



• Florvers purple. 

 1. G. texuifolia, L. Leaves linear, smoothish ; peduncles longer 

 than the flowers; calyx-teeth short, acute. Beck, Bot. p. 268. Icox, 

 Bart. Am. 3. tab. 82. 

 Slender-leaved Gerardia. 



Root annual. Stem 9 to 12 or 15 inches high, slender, somewhat 4-angled by the 

 Recurrence of the leaves, smoothish, much branched above, often forming a pan- 

 iculate bushy top. Leaves 3 fourths of an inch to an inch and half long, linear 

 and very narrow (the widest scarcely a line in width), acute at each end, entire, 

 somewhat scabrous on the upper surface, slightly revolute on the margin, sessile. 

 Peduncles half an inch to an inch long, very slender, often opposite. Calyx cam- 

 panulate, smooth, with minute teeth. Corolla purple, pubescent; limb nearly 

 equally 5-lobcd. Anthers villose. Style a little longer than the longest stamens. 

 Capsule subglobose. 

 flab. Woodlands, and old fields: common. Fl. August— September. FY. Octo. 



Obs. This appears to be nearly allied to G. setacea, Pursh (which is probably 

 the G. erecta, of 3£r.)— of which I have received specimens from my excellent 

 friend and correspondent, the Rev. Mr. Curtis, of N. Carolina. 



2. G. rrnpcnEA, L. Leaves lance-linear, very scabrous; peduncles 

 shorter than fhc flowers ; calyx-teeth subulate. Beck, Bot. p. 2G7. 

 Icox, Bart. Am. 3. tab. 97. 



Purple Gerardia. 



Root annual (biennial, Dart.). Stem 1 to 2 feet high, somewhat 4-anglcd by the 

 Occurrence of the leaves, roughish on the angles, branched. Leaves 3 fourths of 

 an inch to an inch and half long, lance-linear, narrow (the widest scarcely 2 line* 

 wide), acute at each end, entire, very scabrous on the upper surface, revolute on 

 the margin, sessile or subsessilc. Peduncles 1 to 2 or 3 lines in length, somewhat 

 clavate, angular, often opposite. Calyx smooth, with subulate teeth. Corolla deep 

 purple, pubescent, larger than in the preceding, lobes villose- ciliate. Capsule 

 subglobose. 



JIab. Swamps, and moist low grounds : frequent. FU August— Sept. Fr. Octo. 



Obs. This has much general resemblance to the preceding; but is readily dis- 

 tinguished by its stouter growth, rougher leaves, and short peduncles. 



3, G. aurtculata, Jfx. Stem subsimple, roughly hirsute ; leaves 

 ovate-lanceolate, auriculate at base, very scabrous, sessile, margin en- 

 tire ; flowers sessile ; calyx-segments ovate-lanceolate, hirsutely scab- 

 rous and ciliate. Beck, Bot. p. 268.

 ArnicuLATB Gerardia. 



Root annual, coarsely fibrous. Stem 9 to 15 or 13 inches high, erect, terete, 

 roughly and retrorscly hirsute, often 6imple, but the stouter specimens generally 

 branched. Leaves an inch to an inch and half long, and 1 third to 2 thirds of an 

 inch wide, ovate-lanceolate, acute, entire on the margin, closely sessile, with an
