In sandy ground, or the walks and beds of neglected gardens, as 

 well as on shady walls, and gravelly banks, every where. 



Perennial. May — August. 



Root fibrous. Stems 2 — 4 inches long, spreading on the ground 

 in ever)' direction, leafy, round, taking root at their lower joints, 

 and if not disturbed, remaining through the winter, as Mr. Curtis 

 first remarked. Leaves in like manner evergreen, combined by 

 their membranous bages, three-ribbed, linear, about half an inch 

 long, smooth in every part, obtuse, with a very minute bristly 

 point. Floiver-stalks longer tlmn the leaves, smooth. jF7. droop- 

 ing, with white roundish petals. Seeds extremely minute. The 

 late Rev. H. Davies gathered on a green near Beaumaris, in 

 July 1817, a very pretty variety, with rose-like double ftoiceis, 

 of from 27 to 32 petals. This has found its way into some curious 

 gardens. 



A different synonym of Tournefort is quoted in the Prodr. Fl. Gr^c, 

 which nevertheless is correct, though the above ought also to 

 have been noticed. 



2. S. maiitima. Sea Pearl-wort. 



Stems nearly upright, divaricated, smooth. Leaves obtuse, 

 without bristles. Petals none.

Annual. May — August. 



Root tapering, fibrous below. Stems numerous, 2 or 3 inches 

 high, spreading at the bottom, but otherwise erect, branched, 

 leafy, round, smooth, often purplish. Leaves scarcely half the 

 length of the former species, but broader in proportion, thick 

 and blunt, often tipped with a minute point, but no bristle j com- 

 bined by their membranous bases, and sometimes fringed there- 

 abouts. Flower-stalks slender, erect, smooth, usually an inch 

 long. Calyx-leaves broadly ovate, obtuse, with a white mem-
