Arenaria Ciliata L

Stem prostrate, creeping, branches ascending, densely covered with small, nearly round leaves, lower part of stem covered with short hairs. Leaves obovate, shortly acuminate, nearly sessile, glabrous, ciliated towards the base. Flowers terminal or in forks of the branches, solitary, or in a 3-partite cyme, often axillary, flower-stalks erect, filiform, with soft hairs in lower part. Sepals lanceolate, acute, 3-nerved, with narrow membranous margin, glabrous, slightly ciliated towards apex. Petals elliptical, longer than calyx. Capsule nearly globular, longer than calyx, 6-lobed. Seeds kidney-shaped, finely warty.

Damp stony places in the Alpine limestone region up to 9000 feet; frequent. July, August.

Distribution

Eastern, Central, and Western Arps; Carpathians, Pyrenees. Central and Northern Europe as far as Iceland and Spitzbergen. Very rare in the British Isles.

Arenaria Gothica Fries

Sometimes considered a sub-species of A. ciliata, from which it differs by the absence of sterile shoots, and by the longer stems, which are many-flowered. Leaves oblong-lanceolate, ciliate at the base. Sepals oblong-lanceolate, acute, 3-nerved, the lateral being sometimes hardly visible.

It grows by the Lac de Joux in Switzerland, in Sweden, and about Ingleborough and Ribbleshead in Yorkshire, where it is spreading fast. It flowers in June. This rare plant was first discovered in England in 1889. Mr. Wm. Whit well1 gave a detailed account in The Naturalist of its occurrence in several places, and Mr. Arthur Bennett has written on it in the Journal of Botany, November, 1892.

Arenaria Montana L

A prostrate, greyish green plant, forming large masses, with its long, barren shoots. Shortly pubescent, but not glandular. Leaves lanceolate, acuminate, 1-nerved. Flowers large, white. Pedicels 2-3 times as long as calyx, finally recurved. Sepals ovate-lanceolate, 1-nerved, petals oboval, twice the length of the sepals. Capsule sub-globular to ovoid, equalling the calyx, with 3 bidented valves.

Hills, moors, and woods. May to July.

Distribution

Western and Central France, Cevennes, Pyrenees. Spain and Portugal.

This is a frequent and most useful plant for the rock-garden. Most of the Sandworts (Arenaria and Alsine) will do in an ordinary soil, and several of them form useful carpeters. Propagation is usually by division.

Arenaria Purpurascens Ram

This small species from the Pyrenees has ovate-lanceolate leaves, with 1 nerve, and 1-4 rosy-purple flowers in a terminal cyme. Flower-stalks hairy, sepals glabrous, lanceolate-acute, 3-5 nerved. Petals obovate, half as long again as the sepals. Capsule large, cylindrical, opening into 6 erect teeth.

Distribution

Rocks in the Alpine region of the French and Spanish Pyrenees.

It requires plenty of sun, but will grow in ordinary soil and look very attractive, for it has almost the habit of a Saxifrage with star-shaped, purplish flowers. It is propagated from seed or by division.

Arenaria Huteri Kerner

Stem 2 or 3 inches high. Leaves ovate-lanceolate, acute, covered with grey hairs. Flowers large, white. Petals ovate. Sepals 4-6 without nerves.

Stony or sandy places in S. Tyrol. June, July.

"This charming little plant requires plenty of sand in the loam and a south-west aspect. It should be planted in a level part of the rockery, and a top dressing of sand and leaf-mould will help it greatly.
