CABYOPHTLLACE^ 123 



downy, 3 or 4 inches high. Leaves finely subulate. Pedicels very slender, 

 usually about half an inch long. Sepals narrow -lanceolate, finely pointed. 

 Petals obovate or oblong, usually scarcely half the length of the sepals. Cap- 

 sule opening in 3 valves. 



On old walls, stony wastes, or sandy fields, in central and southern Europe, 

 from southern Sweden to the Caucasus. In Britain, apparently confined to 

 some of the eastern counties of England. Fl. summer. 



4. Ovate Sandwort. Arenaria peploides, Linn. 

 (Eng. Bot. t. 189 ; Honckeneya, Brit. Fl. Sea Purslane.) 



Eootstock creeping, with short, procumbent, usually forked flower-stems. 

 Leaves numerous, thick and somewhat fleshy, ovate or elliptical, half an inch 

 long or more, the upper ones smaller and broader. Flowers few, on short 

 pedicels, in small, leafy, terminal cymes, usually more or less unisexual. 

 Sepals thickish, about 21 lines long. Petals scarcely longer. Capsule large, 

 nearly globular, opening in 3 (or sometimes 4 or 5) broad valves, with fewer 

 and larger seeds than in the other Sandworts. 



In maritime sands, in northern and Arctic Europe, Asia, and America, 

 extending down western Europe to Portugal. Rather common aU round 

 Britain. Fl. summer, rather early. 



5. Thyme-leaved Sandwort. Arenaria serpyllifolia, Linn. 

 (Eng. Bot. t. 923.) 



A very much branched, slender, and slightly downy annual, seldom 

 attaining 6 inches. Leaves very small, ovate and pointed. Pedicels from 

 the upper axils or forks of the stem, 2 or 3 Hues long, and slender. Se- 

 pals pointed, about IJ hues long. Petals usually much shorter, but vari- 

 able in size, obovate. Capsule opening in 6 narrow valves. 



On walls and dry sands, or stony, waste places, throughout Europe and 

 central and Russian Asia, except the extreme north. Common in Britain, 

 but more so in the south than in the north. Fl. summer. 



6. Fringed Sand-wort. Arenaria ciliata, Linn. 

 (Eng. Bot. t. 1745.) 



Stems perennial at the base, short, difi'use, generally much branched and 

 matted, the flowering branches 2 or 3 inches high, and more or less downy. 

 Leaves small and ovate, more distinctly stalked than in the thyme-leaved S., 

 veined underneath, and usually fringed with a few stiif hairs on each edge 

 near the base. Flowers much larger than in the last species, on slender 

 pedicels, 3 to 6 hues long, the obovate petals considerably longer than the 

 sepals. Capsule opening in 6 valves. 



In mountain pastures, in northern and Arctic Europe, and at consider- 

 able elevations, in the higher ranges of central and southern Europe. In 

 Britain, only on Umestone chfis near Ben Bulben, in Sligo, Ireland, and on 

 a serpentine hill in Unst, Shetland. Fl. summer. The Shetland specimens 

 belong to an Arctic (maritime ?) variety, with more succulent leaves, seldom 

 fringed, and rather broader sepals, distinguished as a species under the name 

 oi A. norvegica (Eng. Bot. Suppl. t. 2852). 



7. Three-nerved Sandivort. Arenaria trinervis, Linn. 



(Eng. Bot. t. 1483.) 

 A tender, much branched, decumbent or spreading annual, from 4 or 5
