• Acanthocrater — A genus of xerophytic, often spiny, cushion-forming perennial plants belonging to the Plumbaginaceae family. These plants are native to the arid and mountainous regions of Central Asia and the Middle East (particularly Iran and Afghanistan), morphologically adapted to rocky, nutrient-poor soils and harsh climates with extreme temperature fluctuations.
• Agathocles — Tyrant and later King of Syracuse (317–289 BC), a prominent and controversial figure of the Hellenistic era, renowned for his military ambitions and ruthless political tactics. Born into a modest potter's family, he rose to power through military force, waging protracted wars against Carthage and becoming the first leader to carry the conflict directly into African territory to relieve the siege on Sicily.
• Agina — A rare, regional, or archaic designation used in certain historical communities or ancient texts to denote a variety of wild grape or a single grape berry (etymologically similar to the Italian 'acinus'). In a structural and ethnobotanical sense, the word reflects popular names for small, juicy-pulped fruits used in ancient rural medicine or empirical wine production.
• Dyspareunia — A clinical condition or symptom characterized by persistent, acute, or recurrent genital pain that occurs before, during, or after sexual intercourse; dyspareunia. Triggered by both organic causes (pelvic inflammatory diseases, endometriosis, local infections) and psychological factors.
• Alisma genus — A genus of herbaceous, perennial, semi-aquatic plants in the family Alismataceae, commonly known as water-plantains; it comprises species adapted to wetlands, lakes, and ditches, globally distributed across temperate regions. These plants feature rhizomatous stems, variable leaves, and branched inflorescences with three-petaled flowers.
• Grass-leaved water-plantain — A small aquatic plant species in the water-plantain family, commonly known as grass-leaved or ribbonleaf water-plantain; it grows in mud or submerged in shallow fresh or brackish water. It exhibits leaf polymorphism and produces cleistogamous flowers when completely submersed.
• Narrow-leaved water-plantain — A perennial, emergent aquatic plant species in the family Alismataceae, commonly known as narrow-leaved or lanceleaf water-plantain; it grows in shallow water or exposed mud. It is characterized by its narrow, lance-shaped leaves tapering to the petiole, and small pinkish-purple flowers that typically open in the morning.
• Common water-plantain — The type species of perennial herbaceous plants in the genus Alisma, commonly known as common water-plantain or mad-dog weed; it grows in wetlands, shallow pond edges, and wet mud. It features large, broad ovate or heart-shaped leaves resembling terrestrial plantains, and tall branched flowering panicles with tiny pale lilac or white flowers that open in the afternoon.
• Alismataceae — A family of monocotyledonous, herbaceous, perennial, aquatic or marsh plants adapted to life in wetlands and shallow waters. Plants in this family are characterized by laticiferous canals, highly polymorphic leaves arranged in a basal rosette, and 3-merous flowers with distinct green sepals and white or pink petals.
• Amilcar — A masculine given name or surname of Punic (Carthaginian) origin. In universal history, the name is indissolubly linked to Hamilcar Barca, a renowned Carthaginian general and statesman, father of the famous Hannibal, who stood out structurally during the First Punic War through his brilliant campaigns in Sicily and empire expansion in the Iberian Peninsula. It also denotes a historic French performance automobile brand active in the interwar period.
• Bugloss herb — A regional or vernacular term used in certain floristic works to designate species of herbaceous plants adapted to saline or calcareous soils (sometimes correlated with the genus Anchusa or similar plants of the Boraginaceae family). It is characterized by pubescent stems and intensely colored flowers, having a specific ecological role in stabilizing local biotopes.
• Alkanet herb — A popular or regional name attributed to certain herbaceous plants of the Boraginaceae family (often correlated with the genus Anchusa), characterized by stiff hairs on stems and leaves, and small, intensely colored flowers in shades of blue, purple, or red. The plant grows wild in rural areas, roadsides, or fallow lands, occasionally used in traditional empirical medicine.
• Anchusa — A genus of herbaceous plants in the family Boraginaceae, commonly known as bugloss or alkanet. It includes numerous annual, biennial, or perennial species native to Europe, Western Asia, and North Africa, notable for the stiff hairs covering their stems and leaves, and flowers grouped in scorpioid cymes, featuring an intense azure-blue, purple, or white color.
• Anchusa barrelieri — A perennial species of herbaceous plant in the genus Anchusa, commonly known as Barrelier's bugloss. It is native to Southern and Eastern Europe, characterized by erect, stiff stems, branched at the top, and small, bright blue flowers with a yellow or white center, resembling forget-me-nots, arranged in dense inflorescences.
• Anchusa capensis — A species of annual or biennial herbaceous plant in the genus Anchusa, native to South Africa and commonly known as Cape bugloss. It is widely cultivated as an ornamental plant due to its intense cobalt or azure-blue flowers, arranged in dense cymes, and its high tolerance to drought and poor soils.
• Anchusa italica — A perennial species of herbaceous plant in the genus Anchusa, often considered synonymous with Anchusa azurea, commonly known as Italian bugloss. It is a tall, vigorous plant native to the Mediterranean region, covered with coarse, stiff hairs, and widely cultivated for its large, branching cymes of spectacular azure-blue flowers.
• Angelonia — A genus of herbaceous plants or ornamental subshrubs in the Plantaginaceae family (formerly classified in Scrophulariaceae), native to tropical and subtropical regions of the Americas, particularly Brazil and Mexico. Comprising about 30 species, the genus is renowned in horticulture primarily for the species Angelonia angustifolia (popularly dubbed 'summer snapdragon'), prized for its remarkable resistance to drought and excessive heat. The plants feature lanceolate leaves with serrated margins and erect stems supporting inflorescences in long racemes, with bilabiate flowers reminiscent of orchids or snapdragons, ranging in color from purple, blue, and pink, to pure white.
• Angelonia angustifolia — The scientific name for the summer snapdragon, an herbaceous perennial plant (often grown as an annual in temperate climates) in the Plantaginaceae family, native to Mexico and Central America. The plant reaches heights of 30-45 centimeters and features erect stems, narrow lanceolate leaves (angustifolia) with serrated margins, and spectacular inflorescences in long racemes. Its bilabiate flowers, reminiscent of snapdragons or orchids, come in intense shades of purple, blue, pink, or white, being highly prized in horticulture due to outstanding resistance to heat, drought, and direct sun.
