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).

Common Name: SANDWORT Habit: Perennial herb, prostrate (non-flowering stems) or ascending to erect to mat-forming, taprooted. Leaf: needle-like to narrowly linear; vein 1. Inflorescence: terminal, open to head- or umbel-like; flowers 1--many; peduncles, pedicels 0--55 mm. Flower: hypanthium present; sepals 5, +- free, 3--7.2 mm, lance-linear to ovate, glabrous to glandular-hairy; petals 5, 2--18 mm, entire or +- notched; stamens on hypanthium; ovary +- superior, styles 3, 2.5--3 mm. Fruit: capsule, ovoid to urn-shaped; teeth 6, ascending to recurved. Seed: 1--9, +- gray, dark brown, red-brown, yellow-tan, black-purple, or +- black. Etymology: (Greek: solitary or deserted + seed, allusion uncertain) Note: Based in part on molecular evidence (Harbaugh et al. 2010 Intl J Plant Sci 171:185--198), 2 subgenera of Arenaria treated here as Eremogone. eFlora Treatment Author: Ronald L.

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
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.
