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 incl 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 cult, now naturalized in s CA. Aeschynomene rudis Benth. <Noxious weed>, Halimodendron halodendron (Pall.) Voss <Noxious weed> (possibly extirpated), Lens culinaris Medik. are agricultural weeds. Caragana arborescens Lam. only cult. 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
[Annual], perennial herb, vine, unarmed; hairs generally including minute, hooked ones.
Leaf: odd-1- pinnate; axis extended beyond basal leaflets, persistent; leaflets 3, entire or lobed.
Inflorescence: raceme-like ( flowers > 1 per node) [to panicle-like], nodes 1–60, not swollen; bracts, bractlets generally persistent.
Flower: calyx lobes < (>) tube; corolla incurved, sickle-shaped in bud, banner oblong to round, in flower recurved 90°, wings twisted into a platform position, keel incurved, tightly, spirally coiled 1.5 turns; 9 filaments fused, 1 free; style thickened, ± bristly distally, stigma lateral, turned inward.
Fruit: generally dehiscent, linear to oblong rarely rhombic, mostly flat in ×-section.
Seed: 1–20, oblong to reniform or rarely discoid.
± 70 species: neotrop, warm regions. (Classical name, presumably for a bean) [Delgado-Salinas et al. 2006 Syst Bot 31:779–791] Phaseolus coccineus L., Phaseolus lunatus L., Phaseolus vulgaris L. in CA possibly as waifs from cultivation.
