Cherleria.| XII, CARYOPHYLLACER. 67 
Petals none, or rarely linear and very minute. Stamens 10. Styles and 
valves of the capsule 3, Flowers usually wholly or partially unisexual. 
A genus of one or perhaps two species, scarcely distinct from Arenaria., 
1, C. sedoides, Lian. (fig.149). Mossy Cherleria, Cyphel.—Stock very 
densely matted, often several inches diameter, with long roots, the very 
short branches completely covered with closely packed linear leaves, rather 
stiff, and two or three lines long. fedicels slender, from the summit of the 
tufts, with a single erect flower. Sepals about a line long, with three pro- 
minent veins. Stamens shorter than the calyx. Capsule slightly pro- 
truding, opening to the base in 3 valves, and containing but few seeds. 
Arenaria Cherleri, Benth. 
An Alpine plant, not uncommon at considerable elevations in the Pyrenees 
_and Alps of Europe, extending eastward to Greece and_ Transylvania, and 
reappearing in the Scotch Highlands, especially in the Breadalbane range, 
and in Sutherland, although neither an Arctic nor a Scandinavian plant.

VII. ARENARIA. SANDWORT. 
Small, branched annuals, or tufted or prostrate perennials, glabrous, or . 
rarely shortly hairy, with white flowers. Sepals 5. Petals 5, entire. 
Stamens 10, or rarely fewer. Styles 3, very rarely 4. Capsule opening in 
‘as many or twice as many valves. 
A very numerous genus in thenorthern hemisphere without the tropics, 
with afew species also in the southern hemisphere ; distinguished from 
Sagina by the number of styles, from Cerastium and Stellaria by the entire 
petals. The British species are usually distributed into four sections, often 
considered as independent genera, viz., Alsine, with the valves of the cap- 
sule as many as the styles, and many seeds, including 4. verna, A. uli- 
ginosa, and A. tenuifolia; Honcknenya, with the capsular valves as many as 
the styles, and few large seeds, for 4. peploides ; Arenaria, with the capsular 
valves twice as many, and no appendage to the seeds, including JA. ciliata 
and A. serpyllifolia and Mehringia, with the capsule of Arenaria, but with 
shining seeds, having a little appendage to their hilum.

stems erect or decumbent, 2 to 4 inches high, and branched. Leaves subu- 
late, ra hor stiff, the upper ones short and broader. Flowers in rather loose
