The Spruce Home Improvement Review Board.Flowering Time: Mar-Jun Note: Most plants reported as this may be hybrids. Toxicity: Flowers (perhaps all parts) TOXIC. ![]() Bioregional Distribution: NCo, KR, NCoRO, NCoRI, CaRF, s CaRH, n SN, CCo, SnFrB, SCoRO, SCo, s ChI, WTR, PR (San Diego Co.) Distribution Outside California: native to Mediterranean, the Azores, Canary Islands. Flower: calyx 5-7 mm, silky-hairy banner 10-15 mm, ovate, hairy only on midrib or glabrous. Inflorescence: racemes short, dense, axillary, on short-shoots, 15-60 mm flowers 4-10 pedicels 1-3 mm. Leaf: stipules < 2 mm, deciduous petiole < 5 mm leaflets generally 10-15 mm, oblanceolate to widely obovate, length +- 2 × width, hairs generally 0 adaxially, appressed or spreading abaxially. Stem: twigs silvery-silky-hairy, at least in youth. Unabridged Reference: Gibbs & Dingwall 1971 Bol Soc Brot 45:269-316 (native of Canary Islands not in California in pure form), although determining parentage in generally often difficult. Many naturalized California plants are hybrids involving Genista canariensis, Genista monspessulana, and Genista stenopetala Webb & Berthel. (2004 Plant Syst Evol 244:93-119) suggest recognizing Genista in broad sense (i.e., including Retama, Teline, Ulex). Seed: 1-several-seeded, generally arilled.Įtymology: (Latin: from planta genista, from which English Plantagenet monarchs took their name) Note: Generic circumscription difficult, but Pardo et al. Fruit: generally dehiscent, narrowly oblong, compressed, or curved, +- inflated pedicel < 7 mm. Flower: bilateral calyx generally < corolla, 2-lipped, upper 2-lobed, lobes +- 1/2 tube, lower generally 3-toothed, < upper lobes petals 5, generally yellow, banner generally ovate or rounded, outside generally glabrous or variously hairy, keel narrowly oblong to obtuse, +- straight abaxially, often silky-hairy stamens 10, filaments fused style +- abruptly bent at tip. Inflorescence: axillary or terminal, racemes, heads, or flowers in clusters on short-shoots. ![]() Leaf: generally alternate, ternately 1-compound or simple, petioled stipules fused to leaf bases (0). Habit: Shrub, spiny or unarmed generally deciduous. Cercidium moved to Parkinsonia Chamaecytisus to Cytisus Psoralidium lanceolatum to Ladeania.ĮFlora Treatment Author: Martin F. , Halimodendron halodendron (Pall.) Voss (possibly extirpated), Lens culinaris Medik. 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. Ceratonia siliqua L., carob tree (Group 2), differs from Gleditsia triacanthos L. ![]() Laburnum anagyroides Medik., collected on Mount St. evidently a waif, a contaminant of legume seed from Europe. Upper suture of fruit adaxial, lower abaxial. Note: Unless stated otherwise, fruit length including stalk-like base, number of 2° leaflets is per 1° leaflet. ![]() Many cultivated, most importantly Arachis, peanut Glycine, soybean Phaseolus, beans Medicago, alfalfa Trifolium, clovers many orns. Genera In Family: +- 730 genera, 19400 species: worldwide with grasses, requisite in agriculture, most natural ecosystems. Seed: 1-many, often +- reniform, generally hard, smooth. Fruit: legume, including a stalk-like base (above receptacle) or not. 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. Leaf: generally alternate, generally compound, generally stipuled, generally entire, pinnately veined Inflorescence: generally raceme, spike, umbel or head or flowers 1-few in axils.
