NELSON'S STRINGFLOWER


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 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.

Genus: SileneView DescriptionDichotomous Key


Common Name: CATCHFLY, CAMPION
Habit: 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.
Etymology: (Greek: probably from mythological Silenus, intoxicated foster-father of Bacchus, who was covered with foam; from sticky secretions of many species) Note: Silene armeria moved to Atocion. Silene pendula L., a historial waif, known only from 1894 and 1915 collections at Golden Gate Park.

NATIVE
Habit: Perennial herb 2.5--25 cm; caudex branches often many. Stem: decumbent to erect, soft-hairy, hairs straight or wavy. Leaf: not reduced upward, cauline 2--8.2 cm, 6--19 mm wide, elliptic or oblanceolate to obovate. Flower: ascending to erect; calyx 12--24 mm, sparsely to densely canescent, eglandular, 10-veined; corolla narrow- to broad-funnel-shaped, 16--75 mm diam, throat broadly open, petals 20--56 mm, claws sparsely or generally densely ciliate at base, exposed upper claws translucent gray, paired ridges generally weak, appendages 0 or inconspicuous teeth generally < 1 mm, limb 9--32 mm, white, lobed to base, lobes nearly = or outer < inner, inner linear, generally > 10× longer than wide, outer 6--26 mm; stamens +- evenly positioned around throat, filaments opposite sepals generally hidden by ciliate petal margins; styles 3, +- exserted. Fruit: ovoid to spheric, stalked. Seed: 2--2.25 mm, dark reddish brown.

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.
