#Fabaceae
- Abrus — (Botany) A genus of climbing plants in the family Fabaceae (Leguminosae), native to tropical and subtropical regions worldwide, characterized by pinnate leaves and pods containing spherical seeds that are often intensely colored and highly toxic due to their abrin content.
- Rosary pea — (Botany) A species of climbing plant in the genus Abrus, native to the tropics, commonly known as the 'rosary pea', 'jequirity bean', or 'crab's eye'; its small, bright red seeds with a black spot at the base are traditionally used in jewelry and rosaries, but are highly lethal if ingested or chewed, containing abrin.
- Acacia tree — A vast and fascinating genus of woody plants (trees and shrubs) belonging to the Fabaceae family, primarily native to tropical and subtropical regions, famous for its extreme adaptability in arid zones such as the African savannas or the Australian outback. Beyond its ecological and ornamental value, acacia holds major economic and cultural importance, being the source of precious gum arabic and a multi-century mythological symbol of immortality, endurance, and rebirth in various esoteric traditions.
- Peanut — A common popular synonym for the peanut (arachide); the fruit of the herbaceous plant Arachis hypogaea in the Fabaceae family, which develops and matures underground, consisting of a brittle, reticulated pod enclosing edible, oily seeds typically consumed roasted and salted or processed into butter.
- Peanut — Hyphenated spelling variant for the popular name of the peanut (Arachis hypogaea); the fruit of a legume plant that develops underground, consisting of a brittle, reticulated pod enclosing seeds rich in fats and proteins.
- Peanut — Hyphenated popular compound name for the peanut (Arachis hypogaea); an annual legume plant whose pods bury themselves into the soil to mature, providing edible oily seeds with a particularly high nutritional value.
- Peanuts — Plural form for the compound noun 'alună-de-pământ' (or its non-hyphenated variant); designates peanuts (Arachis hypogaea), the underground fruits of a legume plant heavily used in the food industry due to their high content of oils, healthy fats, and proteins.
- Amherstia nobilis — A monotypic genus of plants in the family Fabaceae (Leguminosae), whose sole species is Amherstia nobilis, a tropical tree native to Myanmar (Burma), also known as the 'Pride of Burma'. It is widely recognized as one of the most beautiful ornamental trees in the world due to its spectacular, large structural inflorescences of a bright red color with yellow spots, resembling hanging orchids.
- Amicia — A genus of herbaceous or shrubby plants in the family Fabaceae (Leguminosae), native to the mountainous regions of South America (Andes); it is structurally characterized by compound leaves, large membranous stipules, and yellow flowers arranged in racemes, often used in niche ornamental horticulture.
- Amicia zygomeris — A type species of shrubby plant within the genus Amicia, family Fabaceae, native to the high mountainous zones of Mexico. It is structurally remarkable due to its large, trifoliate or paripinnate leaves, which feature unusually sized purple membranous stipules that protect young buds, and butterfly-shaped yellow flowers.
- Amorpha — A genus of deciduous shrubs or subshrubs in the legume family (Fabaceae), native to North America, characterized by dense, spike-like racemes of purple or blue flowers. Its name reflects the atypical structure of the flowers, which lack the wings and keel characteristic of classic legumes, retaining only the banner petal; the most well-known species in Romania is 'Amorpha fruticosa' (indigobush), a honey-producing but invasive plant.
- Amorpha canescens — The scientific name of a perennial dwarf shrub species in the genus Amorpha, popularly known as leadplant. It is native to the prairies of central North America and is distinguished by its compound leaves covered with fine, grayish-silver hairs, and dense purple-colored spiked inflorescences, being a drought and fire-resistant plant.
- Amorpha fruticosa — The scientific name of a perennial shrub species in the Fabaceae family, native to North America and popularly known in Romania as 'salcâm mic' or desert indigobush. This plant, while appreciated as a valuable honey-producing species and for soil erosion control, exhibits a highly invasive behavior, aggressively colonizing river floodplains, wetlands, and degraded riparian zones, where it displaces native flora.
- Anthyllis — A genus of herbaceous plants or subshrubs in the family Fabaceae, commonly known as kidney vetch, characterized by odd-pinnate leaves and papilionaceous flowers grouped in dense heads surrounded by large, often pubescent bracts.
- Anthyllis montana — The scientific name for mountain kidney vetch, a perennial subshrubby plant in the family Fabaceae native to the mountains of Southern and Central Europe, characterized by prostrate tufts, silvery-pubescent leaves, and dense globose heads of pink or purple flowers.
- Aotus — A taxonomic genus comprising the night monkeys (or owl monkeys) native to the tropical forests of Central and South America, being the only anthropoid monkeys with predominantly nocturnal activity. In botany, it also represents a genus of flowering plants in the Fabaceae family, endemic to Australia, remarkable for their yellow or golden flowers.
- Aotus gracillima — A partial scientific name or cataloged variant (often an abbreviation for an application form, subspecies, or 'apud' publication) referring to the botanical species Aotus gracillima, a shrub endemic to Western Australia. This slender, graceful plant belongs to the Fabaceae family and is characterized by delicate branches and dense inflorescences specific to heathland vegetation.
- Apios — A genus of climbing perennial herbaceous plants within the family Fabaceae (legumes), native to North America and East Asia. The most well-known species is Apios americana (groundnut), historically cultivated by indigenous populations for its edible tubers, rich in starch and protein, which grow strung along the roots like beads.
- Apios americana — A species of perennial climbing plant in the family Fabaceae, native to eastern North America. It is renowned for its edible underground tubers, rich in protein and starch, which grow strung along the roots like beads. Its flowers are highly fragrant, featuring a spectacular coloration in shades of brown, pink, and purple, grouped in dense clusters.
- Peanut — An alternative spelling variant for arahidă (peanut); an annual herbaceous plant in the Fabaceae family, native to South America, widely cultivated for its underground pods containing seeds rich in oils and proteins. In common parlance and older technical texts, the term directly denotes the edible kernel (peanut) used in the food industry, oil extraction, and animal feed.
