The infraspecific taxonomy of Cerastium arvense is subject to many different interpretations. While many subspecies have been recognized, the “actual” number is uncertain because of worldwide distribution, wide range of variation, and conflicting taxonomies.

Plants perennial, clumped and taprooted, or mat-forming and long-creeping rhizomatous. Stems: flowering shoots often decumbent proximally, 5-20(-30) cm, glandular-pubescent distally, pilose-subglabrous, deflexed or spreading proximally; non-flowering shoots present; small tufts of leaves present in axils of proximal leaves. Leaves not marcescent, sessile, ± spatulate proximally; blade linear-lanceolate to lanceolate or narrowly oblong, 4-30 × 0.5-6 mm, apex acute, rarely obtuse, subglabrous to softly pubescent, sometimes glandular. Inflorescences lax, 1-20-flowered cymes, pubescence short, glandular; bracts lanceolate, margins narrow, scarious, glandular-pubescent. Pedicels curved just below calyx, 5-30 mm, 1-6 times as long as sepals, glandular-pubescent. Flowers: sepals narrowly lanceolate to lance-elliptic, 3.5-7 mm, margins narrow, softly pubescent; petals obovate, 7.5-12.5 mm, ca. 2 times as long as sepals, apex 2-fid; stamens 10; anthers 0.8-1.1 mm; styles 5. Capsules cylindric, curved, 7.5-11.5 × 2.5-4 mm, (1-)1.5-2 times as long as sepals; teeth 10, erect, margins convolute.

Cerastium arvense ( Anglèis )

fornì da wikipedia EN

Cerastium arvense is a species of flowering plant in the pink family known by the common names field mouse-ear[1] and field chickweed.[2] It is a widespread species, occurring throughout Europe and North America, as well as parts of South America. It is a variable species. There are several subspecies, but the number and defining characteristics are disputed.[3]

The five white petals are 7.5 to 9 millimetres (0.30 to 0.35 in) long, deeply bilobate with round tips. At the center are ten yellow stamens and five styles.

Description

Cerastium arvense is a perennial herb growing up to 30–45 cm (12–18 in)[3][4] tall. It takes the form of a mat, clump, creeper, or upright flower, and may grow from a taproot or tangled system of rhizomes. It is usually somewhat hairy in texture, often with glandular hairs. The leaves are linear, lance-shaped, or oblong, and a few centimeters in length. The inflorescence may consist of a single flower to a dense cluster of many. The flower has five white petals, each with two lobes, and five hairy green sepals at the base. The fruit is a capsule up to 1.5 cm (0.59 in) long with ten tiny teeth at the tip, which contains several brown seeds.

Cultivation

Gardeners interested in wildflowers disagree on if field mouse-ears should be grown in gardens. Noted rock gardener Louise Beebe Wilder recommended against it in the strongest terms. However C.W. Wood and Claude A. Barr both thought that a specimen selected for good qualities had a place in a garden, such as a groundcover in difficult shady spots.[5]
