Higher Taxonomy
Family: CaryophyllaceaeView DescriptionDichotomous Key

Common Name: PINK FAMILY
Habit: 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.
Genera In Family: 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). Note: Apetalous Caryophyllaceae can also be keyed in Rabeler & Hartman 2005 FNANM 5:5--8.

Genus: EremogoneView DescriptionDichotomous Key

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.
Species In Genus: 90 species: northern temperate, especially western North America, Eurasia. 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.

Eremogone kingii (S. Watson) Ikonn. var. glabrescens (S. Watson) Dorn
NATIVE
Habit: Perennial herb, tufted to funnel-shaped, green. Stem: 1--20(30) cm, +- dull, glandular-hairy or glabrous. Leaf: 3--20 mm, 0.5--1.2 mm wide, generally sharp-pointed, vein 1. Inflorescence: terminal, open; flowers few to many (1--2 in alpine); pedicels 2--15 mm. Flower: sepals 2.5--4(5.5) mm, in fruit enlarging little, acute to acuminate; petals 4--7(10) mm; nectaries < 0.5 mm, rounded. Fruit: 4.5--7 mm. Seed: 2--5, 1.2--1.8(2.5) mm, elliptic-oblong to ovate, compressed, red-brown to dark purple or black; tubercles low, rounded, often elongate.
Ecology: Rocky slopes, summits, canyon floors; Elevation: 2100--4050 m. Bioregional Distribution: CaRH, SNH, SNE, DMtns (San Bernardino Co.); Distribution Outside California: to Oregon, Idaho, Utah. Flowering Time: Jun--Sep Note: Plants from Diamond Mountains (Plumas, Lassen cos.), atypical in habit (funnel-like), height (< 30 cm), sepal length (< 5.5 mm), petal length (< 10 cm), seed length (< 2.5 mm), need study.
Synonyms: Arenaria kingii (S. Watson) M.E. Jones subsp. compacta (Coville) Maguire; Arenaria kingii var. glabrescens (S. Watson) Maguire; Arenaria pumicola Coville & Leiberg var. californica Maguire
Unabridged Note: 1 other var., of Nevada, Utah.
