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 most 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).
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). Note: Apetalous Caryophyllaceae can also be keyed in Rabeler & Hartman 2005 FNANM 5:5--8. Taxa of Minuartia in TJM2 treated here in Cherleria and Sabulina; Pseudostellaria in Hartmaniella and Torreyostellaria; Vaccaria in Gypsophila; Velezia in Dianthus.

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.
