Description
Family Leguminosae (Fabaceae)
Habits: herbs (rarely aquatic), shrubs, vines, lianas (often with tendrils and/or hooks), and trees; stipules present (although often falling early), sometimes large and leaf-like, sometimes modified into spines. Leaves usually alternate, simple, unifoliolate, 3-foliolate, pari- or imparipinnate or bipinnately compound, then pinnae with one to numerous pairs of leaflets; petiole with a basalpulvinus (when unifoliolate then with an apical one as well). Inflorescencesaxillary or terminal, racemes, spikes, panicles, heads or solitary flowers. Flowers usually bilaterally symmetrical, usually actinomorphic in subfamily Mimosoideae, and sometimes actinomorphic in Caesalpinioideae and Papilionoideae, usually hermaphrodite, rarely unisexual; sepals (4-)5, free or fused; petals 4-5, sometimes absent or 1-3, varying in size and shape; androecium usually of 9 or 10 stamens, sometimes reduced to 1, 3, 4, 5 or 6, and sometimes of 50-100+ (part of subfamiliy Mimosoideae), filaments partly fused into a tube or free, anthers dehisce by short to long longitudinal slits, or sometimes by apical pores; nectary(ies) is/are often present around the superiorovary, carpel 1 (rarely many), locule 1 (rarely 2), the ovules 2-many. Fruits usually a one- to many-seeded legume, dehiscent or indehiscent, dry or fleshy, inflated or compressed, sometimes winged (samaroid) or breaking into one-seeded articles (lomentaceous), rarely a drupe, sometimes a craspedium. Seeds sometimes with more or less elaborate aril, usually with a hard seed coat; endosperm little or absent; embryo large, the cotyledons conspicuous.
Subfamily Caesalpinioideae
Habits: trees, shrubs, lianas; root nodules uncommon (present in some Chamaecrista spp.), but many associations with fungi. Leavesbipinnate or paripinnate, rarely simple, 1-foliolate or 2-foliolate, sometimes with specialized glands, very rarely with a tendril (present few Bauhinia spp.). Flowers often bilaterally symmetrical, rarely radially symmetrical, usually relatively large; sepals generally free; petals imbricate in bud, the median petal overlapped by the lateral 4; stamens (1-)10(-50), sometimes dimorphic or heteromorphic, filaments free or fused at the base, exserted or included in the corolla. Seeds often without a pleurogram, but if pleurogram present then closed.
