Trifolium variegatum var. geminiflorum
SMALL-FLOWERED VARIEGATED 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)

Species: Trifolium variegatumView Description 

Habit: Annual, possibly short-lived perennial herb, generally +- glabrous. Stem: prostrate to erect, wiry to fleshy. Leaf: cauline; lower stipules generally entire, upper deeply cut; leaflets generally obovate or wedge-shaped, occasionally narrower. Inflorescence: head-like, included or exserted from leaves, 0.5--2.5 cm wide, 1--many-flowered; involucre wheel-shaped, generally well developed. Flower: calyx 3--10 mm, bell-shaped, tube 10--many-veined, lobes all or some generally > tube, entire or toothed, bristle-tipped; corolla 3.5--16 mm, lavender to purple, tips generally white. Fruit: stalk-like base short or 0. Seed: 1--2. Chromosomes: 2n=16.
Note: Most variable of California clovers; +- 30 entities named but intergrading without clear delimitations; most conspicuous California entities treated as varieties below; keel shape seems taxonomically insignificant; molecular research needed.

Trifolium variegatum var. geminiflorum (Greene) Vincent
NATIVE
Habit: Annual. Stem: mat-forming or not, 1--30 cm. Leaf: leaflets 3--8 mm, generally wedge-shaped. Inflorescence: < 1 cm wide, 1--5-flowered; involucre occasionally reduced. Flower: calyx 3--5 mm; corolla 3.5--9 mm.
Ecology: Open, disturbed, grassy slopes, woodland, generally in dry soil; Elevation: 200--2500 m. Bioregional Distribution: NCo, NCoR, n&c SN, CW, PR; Distribution Outside California: to Washington, Idaho. Flowering Time: Apr--Jul
Synonyms: Trifolium geminiflorum Greene; Trifolium variegatum phase 5 in TJM (1993); Trifolium variegatum var. pauciflorum (Nutt.) McDermott, misappl.
