• Acaena glaucophylla — A species of creeping, evergreen perennial plant native to the mountainous and arid regions of South America (predominantly the Chilean and Argentine Patagonia). It is distinguished by its spectacular glaucous foliage, whose matte blue-green hue is the result of a protective waxy layer that reduces evapotranspiration and reflects intense solar radiation, a major ecological adaptation to alpine tundra or semi-desert conditions.
• Acaena splendens — A species of suffruticose perennial plant in the Acaena genus, native to the high mountainous zones of Chile and Argentina. This plant stands out for its exceptional aesthetics, being entirely covered by a dense indumentum of long, silky, appressed hairs, which give it an intensely glittering (shining) silvery appearance. This structural ecotype acts as an efficient thermal shield against severe nocturnal frosts and extreme ultraviolet radiation at high altitudes.
• Acrophilous — Regarding plants or organisms; growing, developing, or living at high altitudes, in alpine or mountainous regions; alticolous. As a noun, it denotes an organism or individual oriented toward alpine heights.
• Alpine plant — A plant structurally and physiologically adapted to live and grow at high altitudes, within the upper alpine zone or on rocky mountain ridges, displaying specific dwarf or pubescent traits.
• Adenophora bulleyana — A species of perennial, herbaceous plants in the Campanulaceae family, endemic to the mountainous regions and meadows of southwestern China (particularly in Sichuan province). This plant is structurally recognized by its rich inflorescences, composed of bell-shaped blue or violet flowers and thick roots, being widely studied for its ornamental and ecological properties within alpine flora.
• Adenophora himalayana — A species of perennial, herbaceous plants in the Campanulaceae family, distributed across the Himalayan region (Pakistan, India, Nepal, Bhutan, and southwestern China). This mountain plant is structurally characterized by slender stems, lanceolate leaves, and pendulous flowers in shades of pale blue or lavender, adapted to surviving in poor, well-drained soils at high altitudes.
• Adenostyles — A genus of perennial herbaceous plants belonging to the Asteraceae (Compositae) family, structurally distributed throughout the mountainous and subalpine regions of Europe and Asia Minor. These plants are recognized for their large, often cordate or reniform leaves with dentate margins, and for their compound inflorescences of small flower heads with pink, purple, or white tubular florets, developing optimally in moist, rocky habitats or at the edge of coniferous forests.
• Adenostyles alliariae — A species of perennial herbaceous plant in the family Asteraceae, genus Adenostyles, commonly known as adenostyles or alpine colt's-foot; it is structurally characterized by very large, cordate or reniform basal leaves with dentate margins and long petioles, while its compact inflorescences cluster small, pink-purple flower heads. This plant grows wild in mountain and subalpine zones, preferring moist, shaded habitats and nutrient-rich soils.
• Adenostyles tomentosa — A species of perennial, herbaceous plants belonging to the Asteraceae family, native to the mountainous regions of Central and Southern Europe (particularly the Alps, Apennines, and Carpathians). This plant is structurally recognized by its large, cordate leaves covered on the underside with a dense, white-felty pubescence (tomentum), and by its purple capitula-type inflorescences, adapted to the humid climate of montane forests and alpine meadows.
• Adige — The second longest river in Italy (after the Po), originating in the Rhaetian Alps near the borders with Austria and Switzerland, and flowing for over 400 kilometers through the Trentino-Alto Adige and Veneto regions before emptying into the Adriatic Sea. This structural hydrological entity traverses major historical cities such as Verona, playing a crucial role in irrigation, hydropower, and the economic geography of Northern Italy.
• Aethionema — A genus of annual or perennial herbaceous or subshrubby plants belonging to the Brassicaceae (Cruciferae) family, primarily native to the limestone and rocky regions of the Mediterranean basin and Asia Minor. These plants are structurally characterized by often fleshy, glaucous leaves, dense racemose inflorescences made of small decorative pink, purple, or white flowers, and uniquely flattened silicles, being frequently cultivated in alpine rock gardens across temperate zones.
• Aethionema diastrophis — Scientific name of a perennial stonecress species from the Aethionema genus, native to the mountainous and arid regions of Asia Minor, structurally characterized by stems woody at the base, compact glaucous leaves, and dense inflorescences with delicate intense pink flowers. The plant is of particular interest in phytogeography studies and is prized by collectors for its ability to colonize arid rocky crevices.
• Aethionema grandiflorum — Scientific name of the Persian stonecress, a perennial species from the Aethionema genus, native to the mountainous regions of the Caucasus, Iran, and Turkey, considered one of the most spectacular in the genus. It is structurally recognized by its bushy habit, slender stems, glaucous-blue leaves, and large, compact racemose inflorescences formed by numerous intense pink flowers, being widely used as an ornamental rock garden plant.
• Aethionema iberideum — Scientific name of a perennial dwarf stonecress species from the Aethionema genus, native to the rocky alpine zones of Greece, Albania, and Turkey. This plant is structurally characterized by short, trailing stems, small, oval, silvery or glaucous leaves, and dense inflorescences with white or pale pink flowers, resembling the genus Iberis in appearance, making it a highly appreciated niche species in rockeries.
• Aethionema pulchellum — Scientific name of a perennial dwarf stonecress species from the Aethionema genus, native to the calcareous mountainous regions of Turkey, Iran, and the Caucasus. This plant is structurally characterized by trailing or ascending stems, small glaucous-blue leaves, and dense, spherical inflorescences made of numerous delicate pink-purple flowers, being a species highly prized in rock garden landscaping due to its compact habit.
• Bilberry heath — A compact plant formation, mountain meadow, or clearing completely covered by wild bilberry shrubs (Vaccinium myrtillus). These heathlands are specific to acidic soils and cool climates in subalpine zones, serving as a crucial ecological habitat and a major foraging area.
• Alpine bentgrass — A species of perennial herbaceous plants within the genus Agrostis, family Poaceae, structurally adapted to high mountain and alpine climates. This grass grows in small, dense tufts on alpine meadows, rocky ridges, or screes, playing a crucial ecological role in preventing soil erosion in high-altitude zones and serving as forage for wild alpine fauna.
• Rock bentgrass — A species of perennial herbaceous plants within the genus Agrostis, family Poaceae, native to the mountainous regions of Europe (including the Carpathian Mountains). This grass grows in low, dense tufts on stony substrates, cliffs, screes, and alpine meadows with shallow, acidic soils; it is highly resistant to frost, strong winds, and drought, playing a major ecological role in stabilizing high-altitude soils.
• Ajuga pyramidalis — A species of perennial herbaceous flowering plant in the mint family Lamiaceae, commonly known as pyramidal bugle. This small alpine plant is characterized by its dense, erect, pyramid-shaped or conical inflorescence, composed of large, leafy bracts that are often tinged with purple or violet and partially obscure the pale blue tubular flowers, growing natively in mountainous and subalpine regions on acidic soils and shaded meadows.
• Albaiu — The name of an important mountain peak (Albaiu Peak) and a major mountain ridge located in the Baiului (Gârbova) Mountains massif within the Southern Carpathians, Romania. The area represents a sought-after tourist destination for mountain hiking, offering distinct structural panoramas over the Prahova Valley and the Bucegi massif.
