21? PENTANDRIA. MONOGYjNIA. lysimachu. 



I have seen no northern specimens of tliis plant. Mu h- 

 lenb^rg considers it a variety of L. quadri/olia, yet it ap- 

 pears to me very distinct. 



6. L. capitala Ph.: stem subsimplc, punctate; leaves 

 ppposite, sessile, broad-lanceolate, punctate; peduncles axil- 

 lary, elongated ; flowers in dense subglobose heads, 6 — 7- 

 parted. P ur s h Fl. I. ^. X3d, R o em. ^- S c hul I, IV,

Root perpnnial. Stem a foot and a half hi(;h, sornetimes a little 

 branched about the middle, smooth or subvilluse, terete. Leqves 

 opp;)site, lanceolate, becoming broader with age, narrowed at 

 each extremity, when young slightly pubescent beneath, cover- 

 ed with minute black dots. Fioivtra in roundish or ovate 

 heads on peduncles about one third the length of the leaves. 

 Calyx 6 or 7-(rarely 5-)parted \ segments lineor lanceolate. 

 Corolla nearly as long again as the calyx 5 — 6-clefi; segments 

 lanceolate, not dotted. Stamens 6 — 7, much exserted, dilated 

 and united into a short tube at the base ; anthers minute. 

 Germeti nearly round, dotted with red, woolly at the top ; style 

 ratner shorter than the stamens ; stigma capitate. Cafisulc 

 5-valved, 5-seeded. Seeds angular. 



Hab. In the cedar swamp at New-Dnrham, New-Jersey. Cam" 

 bridge, New-York. Stevenson. Fairfield, N. Y. Had" 

 ley. In Pennsylvania. Muhlenberg. June. 



This species sirongly resembles L. thyrsifolia of Europe. 

 In all the specimens which I have examined the calyx and co- 

 rolla were mostly 6-cleft. 



7. h- Tf-jolula jY u 1 1, ; stem quadrangular, branched j 

 leaves opposite, sestjilc, long-linear; margin revolute ; pet 

 dunclcs 1-flowered, subterminai, nodding. jY u 1 1. Gen, I. p,

Root perennial. "Plant very smooth. Stem a foot or eighteen 

 inches high. Radical leaves spathuiatc, on long petioles; 

 those on tiie stem about 3 inches long and 2 lines broad, with 

 several shorter ones in the axils, rallier obtuse, narrowed at the 

 base, very entire, not punctate. Mowers mostly on the svim- 

 mit of the stem, and on the extremity of the branches, pe- 

 duncles slender, at length elongated. Segments of the calyx- 

 ovate-lanceolate, acuminate. Segments of the corolla round- 

 ovate, abruptly acuminate, undulate. Stamens subequal, vvitli 

 ^intermediate teeth ; anthers linear-oblong, very large. ' Cafi- 

 sule 5-valvcd, many-seeded.
