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 , 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.
± 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. [Lewis et al. (eds) 2005 Legumes of the World. RBG, Kew] 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. <Noxious weed>, Halimodendron halodendron (Pall.) Voss <Noxious weed> (possibly extirpated), Lens culinaris Medik. are agricultural weeds. Caragana arborescens Lam. only cultivated. Ononis alopecuroides L. <Noxious weed>, Sphaerophysa salsula (Pall.) DC. <Noxious weed> all evidently extirpated. Cercidium moved to Parkinsonia; Chamaecytisus to Cytisus; Psoralidium lanceolatum to Ladeania. —Scientific Editors: Martin F. Wojciechowski, Thomas J. Rosatti.
Key to Fabaceae
[Perennial herb], shrub, small tree, armed or not, glandular or not. Leaf: odd- or even-2-pinnate, alternate. Inflorescence: generally raceme, axillary or terminal. Flower: ± bilateral; sepals ± free, overlapped above; stamens 10, ± exserted, free. Fruit: dehiscent or not, inflated or flat.Key to Caesalpinia
± 25 species: tropics, warm temperate America, Africa, Arabia; some cultivated. (A. Cesalpino, Italian naturalist, physician, 1519–1603) [Lewis 1998 Caesalpinia .... RBG, Kew] Caesalpinia virgata now treated as Hoffmannseggia microphylla.
Plant < 4 m, unarmed; evergreen. Stem: ± glandular-hairy. Leaf: 1–2 dm, glabrous; stipules small, persistent; 1° leaflets 16–30, opposite or not, 1.5–3 cm; 2° leaflets 14–22, < 8 mm. Inflorescence: < 10 cm, wider below, many-flowered; main axis, pedicels glandular-hairy. Flower: sepals 1.5–2 cm, oblong-elliptic, glandular; petals yellow with orange marks; stamens 8–10 cm; ovary densely glandular-hairy. Fruit: dehiscent, 6–12 cm, 1.9–2 cm wide, oblong, flat, ± curved to straight, twisted when mature, gland-dotted. Seed: 6–10, ovate, brown.
Uncommon. Disturbed areas; < 1000 m. South Coast, San Gabriel Mountains, Peninsular Ranges, Mojave Desert, expected elsewhere; native to Argentina, Uruguay, widely cultivated in arid temperate, tropics. Fruit, seeds TOXIC. May–Aug [Online Interchange]
