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. eFlora Treatment Author: Martin F. Wojciechowski, except as noted Scientific Editor: Martin F.

Common Name: LOCOWEED, OXYTROPE Habit: Perennial herb, unarmed, hairy. Leaf: odd-1-pinnate, generally basal; stipules generally partly fused to petiole, initially forming a sheath, or free. Inflorescence: raceme, generally scapose, spike- or head-like or not, or 1--2-flowered; bracts generally persistent. Flower: calyx lobes < tube; corolla pink-purple, white, or +- yellow, keel tip beaked; 9 filaments fused, 1 free; style, stigma glabrous. Fruit: erect to reflexed, generally persistent, oblong to lanceolate, +- inflated, +- 2-chambered, septum from upper suture, partial to complete. Etymology: (Greek: sharp keel) Toxicity: Seriously TOXIC: causes "staggers" in livestock, mostly outside California. eFlora Treatment Author: Martin J.

Oxytropis deflexa (Pall.) DC. var. sericea Torr. & A. Gray
NATIVE Habit: Plant green or gray. Stem: few to several. Leaf: basal and generally 1--3 cauline; stipules free to fused around petiole, 7--20 mm; leaflets 15--31, 3--20 mm, lanceolate to ovate, flat or folded. Inflorescence: spike-like, open; flowers 10--25, quickly reflexed; peduncle generally > 15 cm, often curved. Flower: corolla 5--10 mm, dull white to pale lilac or blue, +- >= calyx. Fruit: reflexed, 3--4.5 cm, elliptic or oblong, membranous or papery, incompletely 2-chambered; stalk-like base generally short. Chromosomes: 2n=16.

MAP LEGEND View all CCH records 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.
