• Alchemilla — A genus of perennial herbaceous plants in the Rosaceae family, primarily distributed throughout temperate and arctic regions of Europe and Asia, popularly known as lady's mantle. These plants are characterized by lobed leaves, often folded like a fan, which retain dew droplets through guttation, and tiny, greenish or yellowish flowers, being widely utilized in traditional medicine due to their astringent and anti-inflammatory properties.
• Alchemilla alpina — A species of perennial herbaceous plant in the genus Alchemilla, distributed across the alpine and subalpine zones of Europe (including the Carpathian Mountains), popularly known as alpine lady's mantle. It is distinguished from other related species by its leaves deeply divided into 5–7 digitate lobes, whose margins and lower surfaces are covered with silky, silvery hairs, giving it a shiny appearance and structural protection against the harsh mountain climate.
• Alchemilla hybrida — A species of perennial gemstone herbaceous plant in the genus Alchemilla (Rosaceae family), characterized by stems and petioles entirely covered with dense, erect, or spreading hairs, and lobed leaves with stipules often tinted pink-purple at the base. This plant structure is distributed across mountain and subalpine meadows of Central and Eastern Europe, heavily studied for its taxonomic complexity driven by apomictic reproduction.
• Alchemilla mollis — A species of perennial herbaceous plant in the genus Alchemilla, native to southeastern Europe and the Caucasus, widely cultivated globally as an ornamental garden plant. It is structurally recognized by its large, rounded leaves, velvety and soft to the touch (due to a dense layer of fine hairs), featuring a bright chartreuse green color, and by abundant clusters of tiny, golden-yellow flowers appearing in early summer.
• Alchemilla vulgaris — The type species of perennial herbaceous plant in the genus Alchemilla (Rosaceae family), popularly known as common lady's mantle. It is a structurally distinct plant featuring palmate-lobed leaves with serrated margins covered in fine hairs, and tiny, yellow-green flowers grouped in cyme inflorescences; it is historically recognized in phytotherapy for its astringent, hemostatic, and healing properties in gynecological disorders.
• Imperial purple robe — An imperial robe or mantle dyed with Tyrian purple, worn in the past by Byzantine emperors, Romanian rulers, or high church prelates as an official insignia of state or ecclesiastical power and sovereignty. In old legal and religious texts, the term describes the princely chlamys of a deep red color, symbolizing the imperial dignity and supreme authority granted upon ascending the throne.
• Asthenosphere — A layer ofthe solid Earth located in the upper mantle, directly below the lithosphere (at a depth between approximately 100 and 410 kilometers); it is characterized by rocks in a plastic, viscous, and partially molten state due to high temperatures and pressures, allowing the slow movement of overriding tectonic plates through convection currents.
• Auer — A proper noun of Germanic origin, famous in the history of science due to the Austrian chemist Carl Auer von Welsbach (1858-1929), discoverer of praseodymium and neodymium and inventor of the incandescent gas mantle. It also designates a village in South Tyrol (Italy).
• Auer von Welsbach — The full name of Baron Carl Auer von Welsbach (1858-1929), a celebrated Austrian chemist, inventor, and entrepreneur. He is globally recognized for isolating and discovering the chemical elements praseodymium and neodymium in 1885, as well as for developing the incandescent gas mantle and the osmium filament.
