Root perennial, creeping. Siem erect, 1 — 2 feet high, much 

 branched, quadrangular, with the sides concave. Leaves op- 

 posite, narrowed into a petiole at the base, smooth, sprinkled 

 with minute resinous dots; upper ones incisely toothed ; the 

 serratures growing deeper on the lower leaves. Flowers very 

 minute, crowded into whorls. Calyx about the length of the 

 corolla, scabrous, sprinkled with resinous dots ; each segment 

 with a strong midrib, which is continued beyond the point into 

 a short spine. Corolla white, with a tinge of red, bearded 

 within. Filaments a little shorter than the tube ; anthers di- 

 dymous. Style 2-cleft; divisions reflected. Seeds obovate, 

 compressed, with an acute margin. 



Hab. In wet meadows and in ditches. August. 



This plant may yet prove a distinct species from the L. 

 curojixus of the old world, though I shall for the present con- 

 sider it merely as a variety. I have no hesitation in referring 

 to the plant described above, the L. angustifolius oi Elliott^ 

 as it agrees exactly with his description, and with specimens 

 thus named sent me from N. Carolina by Mr. Sc hiv einitz. 

 The L. exaltatus of Pursh and Elliott, and L. sinuatus 

 of the latter, do not appear to be distinct from this species.

 narrow and entire at the base; calyx shorter than the seed, 

 spineless. Willd. Spec. I. p. 121. M ich. Fl.\. p. 14.
