Trifolium fragiferum
STRAWBERRY CLOVER

Higher Taxonomy
Family: Fabaceae (Leguminosae)View DescriptionDichotomous Key

Common Name: LEGUME FAMILY
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: TrifoliumView DescriptionDichotomous Key

Common Name: CLOVER
Habit: Annual, perennial herb, unarmed. Leaf: generally palmately compound; stipules conspicuous, partly fused to petiole, generally papery or membranous; leaflets generally 3, occasionally 5--9, +- toothed or wavy. Inflorescence: raceme (generally umbel-like), head, or spike, axillary or terminal, generally many-flowered, generally involucred, generally peduncled; inflorescence bracts 0 or forming vestigial ring or involucre; flower bracts present or not. Flower: generally spreading to erect, generally becoming reflexed; corolla generally purple to pale lavender, occasionally yellow, persistent after flower; 9 filaments fused, 1 free. Fruit: generally indehiscent but generally breaking, short, plump, generally enclosed in corolla; base generally stalk-like. Seed: 1--6.
Species In Genus: +- 300 species: temps, tropical mountains, northern hemisphere, South America, Africa; foodplant for lepidopterans, cultivated as green manure in crop rotation, fodder. Etymology: (Latin: 3 leaves)

Trifolium fragiferum L.
NATURALIZED
Habit: Perennial herb, creeping and rooting or cespitose, glabrous. Leaf: +- basal; stipules generally overlapped; petiole >> blade; leaflets 0.5--2 cm, elliptic to obovate. Inflorescence: head-like, 8--12 mm wide, in fruit +- 2 cm wide, spheric, +- woolly, red or brown; involucre bracts +- 2 mm, +- free, green. Flower: calyx hairy, in fruit inflated, lobes linear, lower 2 bristle-like, > upper 3; corolla 5--6 mm, pink, quickly +- hidden by calyx. Seed: 1--2. Chromosomes: 2n=16.
Ecology: Roadsides, generally in saline soil; Elevation: < 1500 m. Bioregional Distribution: NCoR, ScV, SCoR, SW, MP, W&I, expected elsewhere; Distribution Outside California: sporadic in much of United States; native to Europe, Africa. Flowering Time: May--Aug Note: Cult.
