Coronilla varia

Higher Taxonomy
Family: Fabaceae (Leguminosae)View DescriptionDichotomous Key
Habit: Annual to tree. Leaf: generally alternate, generally compound, generally stipuled, generally entire, pinnately veined Inflorescence: generally raceme, spike, umbel or head; or flowers 1--few in axils. Flower: generally bisexual, generally bilateral; hypanthium 0 or flat to tubular; sepals generally 5, generally fused; petals generally 5, free, fused, or lower 2 +- united into keel (see 3, Key to Groups, for banner, wings); stamens 10 or many (or [1], 5, 6, 7, 9), free or fused or 10 with 9 filaments at least partly fused, 1 (uppermost) free; pistil 1, ovary superior, generally 1-chambered, ovules 1--many, style, stigma 1. Fruit: legume, including a stalk-like base (above receptacle) or not. Seed: 1--many, often +- reniform, generally hard, smooth.
Genera In Family: +- 730 genera, 19400 species: worldwide; with grasses, requisite in agriculture, most natural ecosystems. Many cultivated, most importantly Arachis, peanut; Glycine, soybean; Phaseolus, beans; Medicago, alfalfa; Trifolium, clovers; many orns. Note: Unless stated otherwise, fruit length including stalk-like base, number of 2° leaflets is per 1° leaflet. Upper suture of fruit adaxial, lower abaxial. Anthyllis vulneraria L. evidently a waif, a contaminant of legume seed from Europe. Laburnum anagyroides Medik., collected on Mount St. Helena in 1987, may be naturalized. Ceratonia siliqua L., carob tree (Group 2), differs from Gleditsia triacanthos L. in having evergreen (vs deciduous) leaves that are 1-pinnate (vs 1-pinnate on spurs on old stems, 2-pinnate on new stems) with 2--5(8) (vs 7--17) 1° leaflets, commonly cultivated, now naturalized in southern California. Aeschynomene rudis Benth. , Halimodendron halodendron (Pall.) Voss (possibly extirpated), Lens culinaris Medik. are agricultural weeds. Caragana arborescens Lam. only cult. Ononis alopecuroides L. , Sphaerophysa salsula (Pall.) DC. all evidently extirpated. Cercidium moved to Parkinsonia; Chamaecytisus to Cytisus; Psoralidium lanceolatum to Ladeania.

Genus: CoronillaView DescriptionDichotomous Key

Habit: [Annual] perennial herb, small shrub, unarmed. Leaf: alternate, odd-1-pinnate (simple); stipules generally conspicuous, free or fused; leaflets generally 3--several. Inflorescence: axillary umbel, peduncled, flowers generally 10--20. Flower: corolla white or pink to purple to yellow; 9 filaments fused, 1 free; style glabrous. Fruit: indehiscent, linear to lanceolate, segments 1--12. Seed: several.
Species In Genus: +- 25 species: Mediterranean, northern Africa, central and southern Europe to western Asia, naturalized elsewhere. Etymology: (Latin: small crown, for shape of inflorescence) Note: Coronilla valentina L. subsp. glauca (L.) Batt. (perennial herb, small shrub; corolla yellow) is a waif in PR.

Coronilla varia L.
Habit: Erect to spreading or vine-like, to 1 m. Stem: angled, hairs 0 to sparse. Leaf: stipule tips dark; petiole 0 to short; leaflets 11--19, 1--2 cm, obovate to oblong, glabrous.

Fruit: with 3--12 segments, generally 2--6 cm, linear, longitudinally ridged, 4-angled. Chromosomes: 2n=24.

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.
