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. Seed: appendage generally 0 (present in Moehringia).
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 ferrisiae (Abrams) R.L. Hartm. & Rabeler
Habit: Perennial herb, tufted, green. Stem: (10)20--40(100) cm, rounded, +- dull, glabrous to glandular-hairy. Leaf: 20--60 mm, 0.5--1 mm wide, subsucculent or not succulent, spine tipped, vein 1. Inflorescence: cymes, terminal, open; flowers many; pedicels 15--55 mm. Flower: sepals 3--4.3 mm, in fruit < 5.5 mm, acute to acuminate; petals 6--9 mm; nectaries rounded, 0.3--0.4 mm. Fruit: 6--7 mm. Seed: 4--5, 1.3--3.2 mm, +- round to ovate, compressed, red-brown to +- black; tubercles low, rounded to conic.
Ecology: Pine, oak woodland, granitic alluvium on foothills, mountain slopes; Elevation: 1450--2900 m. Bioregional Distribution: c&s SNH, SnJt, SNE; Distribution Outside California: to Utah. Flowering Time: Apr--Aug Note: Elevation to sp. rank based primarily on nectary morphology (see key); for discussion, see Hartman et al. (2005 FNANM 5: 65).

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.
