The stem is copiously divided from the very bottom, forked in the 

 upper part, leafy, round, rigid, rough with very short deflexed 

 hairs, forming a little bushy herb, 3 or 4 inches high. Leaves 

 small, ovate, acute, ribbed, clotted, minutely fringed, greyish 

 green, without stipulas. Ft. small, white, solitary, from the 

 forks of the stem, on downy, round, upright stalks. Calyx- 

 leaves ovate, acute, hairy, with a membranous border ; the 2 in- 

 nermost with 3 ribs only. Pet. rather shorter than the calyx. 

 Caps, ovate, with 6 teeth. Seeds tawny, roughish.

Annual. June. 



Stein like the last, but the hairs, if any, are long and spreading. 

 Leaves awl-shaped, 3 -ribbed at the back, combined at the base. 

 Flower-stalks capillary, erect, longer than the leaves. Fl. very 

 small, white, with red anthers. Calyx- leaves lanceolate, 3-ribbed, 

 taper-pointed, with membranous edges. Stam. certainly 10 in 

 general, but they are found in Switzerland of every number 

 from 3 to 1 0, and may vary no less in England. Styles 3. Caps. 

 very delicate and pellucid, of 3 narrow valves, recurved at the 

 point, longer than the calyx. The whole herb is occasionally 

 hairy or smooth, sometimes viscid ; which, with the variableness 

 of the stamens, caused Haller to describe it twice over ; and 

 Linnaeus sometimes confounded it with his own Jlsine segetalis, 

 a very distinct plant.
