Flower: generally bisexual, radial; hypanthium often present but obscure; sepals (4)5, +- free or fused into a tube, margins generally scarious, more so on inner 2 or not, tube generally not scarious, awns generally 0; petals (4)5 or 0, generally tapered to base (or with claw long, limb expanded), entire to 2--several-lobed, limb generally without scale-like appendages adaxially, generally without ear-like lobes at base; stamens generally 10, generally fertile, generally free, generally from ovary base; nectaries 0 or 5; ovary superior, generally 1-chambered, placentas basal or free-central, styles 2--5 with 0 branches or 1 with 2--3 branches. Fruit: capsule or utricle (rarely +- dehiscent), generally sessile. Seed: appendage generally 0 (present in Moehringia). Genera In Family: +- 100 genera, 3000 species: widespread, especially arctic, alpine, temperate northern hemisphere; some cultivated (Agrostemma, Arenaria, Atocion, Cerastium, Dianthus, Gypsophila, Lychnis, Sagina, Saponaria, Silene).

Habit: Annual, perennial herb, erect to mat-forming; taproot or rhizomes present. Leaf: blade linear to ovate; vein 1; axillary leaf clusters generally 0. Inflorescence: terminal or axillary; flowers few to many, open to dense; pedicels 1--36+ mm. Flower: sepals (4)5, 3--12 mm, free, lanceolate to ovate, hairy to glandular-hairy, hairs generally not exceeding tip; petals 0 or (4)5, 2.5--15 mm, +- 2-lobed, white [purple tinged]; stamens (4,5)10; styles (4)5, 0.5--3.3 mm. Fruit: capsule, cylindric, often +- curved in upper 1/2; teeth (8)10, spreading to recurved. Seed: several to many, pale to red-brown. Etymology: (Greek: horn, from fruit shape) eFlora Treatment Author: Ronald L. Hartman (deceased) & Richard K. Rabeler Reference: Morton 2005 FNANM 5:74--93
Cerastium arvense L. subsp. strictum Gaudin
NATIVE Habit: Perennial herb, generally not flowering 1st year, 5--20(30) cm, glandular-hairy above, hairs +- longer below. Stem: non-flowering (mat-forming) and flowering (+- erect). Leaf: on flower stem generally 8--25 mm, linear or lanceolate, +- glabrous or not; axillary leaf clusters present, especially below. Inflorescence: bract margins generally scarious in distal 1/4; pedicels in fruit 1--4 × sepals. Flower: parts 5; calyx 4.2--6(7) mm, glandular-hairy, rarely with hairs exceeding tip, scarious margin of outer sepals < 0.2 mm wide; petals 7.5--9 mm, 3--6 mm > sepals. Fruit: 7.5--11 mm. Seed: +- 1--1.2 mm. Chromosomes: 2n=36. Ecology: Moist seeps, shaded areas, grassy, generally rocky or sandy slopes; Elevation: 600--1850 m. Bioregional Distribution: KR, c SNF, n&c SNH, SnFrB; Distribution Outside California: North America (except southeastern); South America, Europe. Flowering Time: Spring Note: Can be difficult to distinguish from Cerastium viride (see Morton). Synonyms: Cerastium arvense var. strictum (Gaudin) W.D.J. Koch Unabridged Note: 1 other subsp., in northeastern North America, native to western Europe. Jepson eFlora Author: Ronald L. Hartman (deceased) & Richard K.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
