#synonym
- Altamiranoa elongata — A historical scientific Latin designation (currently a taxonomic synonym for Sedum elongatum or related species) that designated a perennial succulent plant within the Crassulaceae family, native to the mountainous regions of Mexico. This species was structurally characterized by elongated, erect, or decumbent stems (elongata) and densely arranged fleshy leaves adapted for water storage in arid rocky habitats.
- Altamiranoa guatemalensis — A historical scientific Latin designation (currently a taxonomic synonym for species reclassified under the Sedum or Echeveria genus) that designated a perennial succulent plant within the Crassulaceae family, native and endemic to the mountainous and arid regions of Guatemala. This species was structurally characterized by fleshy leaves optimized for water storage and compact inflorescences adapted to Central American alpine microclimates.
- Ampelideae — A terminological variant or collective name from a classical classification system (Ampelideae) used as a synonym for the Vitaceae (or Ampelidaceae) family. This group includes climbing dicotyledonous plants, shrubs, and lianas distributed across temperate and tropical zones, with the grapevine serving as the reference element.
- Andromeda lucida — A historical botanical name (synonym) previously used for the species Lyonia lucida, an evergreen shrub native to the coastal plains and bogs of the southeastern United States. Belonging to the Ericaceae family, this structural plant is noted for its shiny, elliptical leaves with smooth margins and a prominent marginal vein, producing white or pink axillary flowers.
- Anesthesiologist — A rare lexical form or neologistic regional variant used to denote a physician specialized in anesthesiology and intensive care, synonymous with the standard term anesteziolog. His structural activity involves the administration of narcotic pharmacological agents and maintaining the patient's homeostasis throughout all stages of a surgical procedure.
- Anota harrisoniana — A synonymous scientific name used in historical botanical nomenclature for an epiphytic orchid species, currently classified structurally as a variety of Rhynchostylis gigantea (or closely related species within the genus Rhynchostylis). This tropical plant is native to Southeast Asia and is recognized by its dense, cylindrical inflorescences made of pristine white or spotted, intensely fragrant flowers, making it a taxon of high interest in plant morphology studies.
- Antholyza cunonia — A historical scientific name and significant synonym for Gladiolus cunonius, a bulbous perennial plant in the family Iridaceae native to coastal South Africa, famous for its bright scarlet-red flowers with a hood-like upper tepal adapted for sunbird pollination.
- Arecastrum — An archaic or synonymic taxonomic genus in the family Arecaceae (Palmae), historically used to classify certain tropical and subtropical palm species from South America, notably the queen palm, modernly reclassified under the genus Syagrus (as Syagrus romanzoffiana). In a structural-botanical sense, the term describes arborescent plants featuring a solitary, smooth, ringed trunk, a rich crown of long pinnate leaves, and branched inflorescences producing yellow fleshy drupe-type spherical fruits.
- Aregelia — A taxonomic genus of perennial herbaceous plants in the family Bromeliaceae, historically used in botany as a synonym or modernly reclassified as a section within the genus Neoregelia. In a structural-botanical sense, these epiphytic or terrestrial plants from South American tropical rainforests are characterized by leaves arranged in a dense rosette layout, forming a central water reservoir tank, and short, compact inflorescences whose surrounding bracts turn bright shades of red or pink during the blooming cycle.
- Artocarpus communis — A taxonomic synonym frequently utilized in classic scientific literature for the species Artocarpus altilis, popularly known as the breadfruit tree. In plant biology, this designation indicates a large tropical tree widely cultivated in equatorial zones for its massive, starch-rich compound fruits providing fundamental nutrients.
- Aruncus vulgaris — A historical scientific name or taxonomic synonym used in the past for the species Aruncus dioicus, popularly known as 'goat's beard'. It is a robust, perennial, Eurasian and North American herbaceous plant that grows in shady mountain forests and forest edges, developing large clumps over one meter high, with large compound leaves and massive panicles of white flowers, either male or female, arranged on separate individuals (dioecious plant).
- Assertoric — A semantic variant perfectly equivalent to the term 'asertoric'; asserting or denying a state of affairs as being real and empirically unquestionable. Used particularly in classic translations of formal logic treatises to define the contingent truth value of a declarative proposition.
- Astatine — An alternative, synonymous, and tolerated name within the scientific community for the chemical element 'astatin'; it follows the classical terminological pattern of metals and metalloids (with the suffix '-ium'), occasionally used in textbooks or older technical translations to denote the element with atomic number 85.
- Baeria genus — A genus of annual herbaceous plants in the Asteraceae family, native primarily to western North America, scientifically recognized as a partial synonym of the genus Lasthenia. These small-sized plants are characterized by bright yellow flower heads and linear, opposite leaves, adapted to ephemeral soils and coastal vernal pools.
