Annual to perennial herb; rarely dioecious (Silene), taprooted or rhizome generally slender. Leaf: simple, generally opposite (subwhorled), entire, pairs at nodes often ± connected at bases; stipules generally 0; petiole generally 0. Inflorescence: generally cyme, generally open; flowers 1–many; involucre generally 0 (present in Dianthus, Petrorhagia). 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).
83 or 89 genera, 3000 species: widespread, especially arctic, alpine, temperate northern hemisphere; some cultivated (Agrostemma, Arenaria, Cerastium, Dianthus, Gypsophila, Lychnis, Sagina, Saponaria, Silene, Vaccaria).

Key to Caryophyllaceae
Annual to perennial herb, ± erect, from caudex, taproot, or rhizome; rarely dioecious. Leaf: petioled or not; linear to oblanceolate, vein 1. Inflorescence: generally terminal, open to dense; flowers few to many, pedicels generally 5–40+ mm. Flower: generally erect, generally bisexual; sepals 5, fused, tube prominent, 4–38 mm, 2–13 mm diam, cylindric to bell-shaped, rounded, hairs various or 0 (walls between hair cells generally clear), veins generally 10+, generally dark, lobes or teeth 1–13 mm, < tube, triangular to linear; petals 5, 6–62 mm, claw long, limb entire or 2–6-lobed, appendages at junction of claw, limb 0–6, generally 2, basal lobes present or 0; stamens generally fertile, bases fused with petal bases to ovary stalk; ovary chamber 1 or ± incompletely 3–5, styles 3(4,5; if 5 then flowers unisexual, taxon dioecious), 1–35 mm. Fruit: capsule, cylindric to ovoid; stalk (from ovary stalk) 0–7 mm, generally glabrous; teeth 6 or 10, ascending to recurved. Seed: many, gray to red, brown, or black.Key to Silene
700 species: North America, South America, Eurasia, Africa, introduced ± worldwide. (Greek: probably from mythological Silenus) [Morton 2005 FNANM 5:166–214] Oxelman et al. (2001 Nordic J Bot 20: 743–748) including data for disarticulation of Silene into four additional genera, including for California Lychnis (Lychnis coronaria) and Atocion (Atocion armeria (L.) Raf., as Silene armeria here).
Unabridged etymology: (Greek: probably from mythological Silenus, intoxicated foster-father of Bacchus, who was covered with foam; from sticky secretions of many species)
Perennial herb 10–55 cm; caudex branches few to many. Stem: erect, ± scabrous to puberulent, glandular above or not. Leaf: ± gradually reduced upward, stiff to flexible; lower 3–9 cm, 2–9 mm wide, generally lanceolate; middle spreading to erect; upper 1–4.5 cm, 2–6 mm wide, linear to lanceolate. Flower: calyx 10–15 mm, ± densely puberulent to glandular-puberulent, 10-veined, lobes 2–5 mm; petal claw ciliate throughout or at base, appendages 2, limb white to rose, lobes 2; stamens ± = petal claws; styles 3(4), exserted. Fruit: oblong to ovoid; stalk 2–5 mm, puberulent. Seed: 1–1.5 mm, dark brown to black.
