#thus

• Acanthus — A sculptural or pictorial decorative element characteristic of classical architectural styles (especially the Corinthian and Composite orders), stylized after the deeply notched and sinuous leaves of the Mediterranean plant Acanthus. Initially used in Greek and Roman Antiquity to adorn the capitals of columns, the acanthus became a universal ornamental motif in art history, being adopted and reinterpreted in Renaissance, Baroque, and Neoclassicism.
• Acanthus — A perennial herbaceous plant in the Acanthus genus, Acanthaceae family, native to the Mediterranean region and tropical zones, characterized by large, deeply incised, often spiny leaves and tall spike-like inflorescences with white, purple, or pink flowers. In horticulture, it is cultivated as an ornamental backdrop plant due to its imposing architecture, being also the plant whose leaves served as the historical model for creating the famous architectural ornament of the Corinthian order.
• Acanthus — The type genus of the Acanthaceae family, comprising around 30 species of perennial herbaceous plants or shrubs native to the temperate and tropical regions of Southern Europe, Africa, and Asia. The plants are recognized by their majestic, deeply lobed, and frequently spiny leaves, and by their erect, dense flower spikes bearing bilabiate flowers. Its name holds immense cultural resonance, as its leaves served as the unchanging historical model for Corinthian and Composite architectural capitals.
• Acanthus arboreus — A species of erect shrub or small tree in the Acanthus genus, native to the tropical regions of East and Northeast Africa (such as Ethiopia, Sudan, Kenya, and Uganda). Unlike the predominantly herbaceous species of this genus, this taxon develops vigorous woody stems that can reach heights of 4 to 6 meters. It is characterized by large, deeply lobed, and heavily spiny leaves, and spectacular dense terminal flower spikes with large, bright pink or purple flowers protected by serrated green bracts.
• Acanthus carolialexandri — A rare species of perennial herbaceous plant in the Acanthus genus, native to the Balkan Peninsula (endemic to certain arid and mountainous regions of Greece). The taxon is characterized by leaves tightly arranged in a basal rosette with sharp lobes, and rigid flower stalks bearing flowers protected by spiny bracts. It represents a niche floristic element adapted to rocky Mediterranean microclimates, primarily described and studied in East European phytotaxonomic literature.
• Acanthus longifolius — A species of perennial herbaceous plant in the Acanthus genus, Acanthaceae family, native to the Balkan Peninsula and neighboring regions of Southeastern Europe. It stands out for its unusually long, elegant, deeply and sinuously lobed leaves, which lack aggressive spines at their tips. This massive foliar structure forms a dense basal rosette from whose center rigid flower stalks rise in early summer, bearing spectacular spike-like inflorescences with white or purple bilabiate flowers framed by large, colorful bracts.
• Acanthus mollis — A species of large, rhizomatous, perennial herbaceous plant in the Acanthus genus, native to the Mediterranean region. It is characterized by large, glossy dark green leaves, deeply lobed, but with soft, flexible, and spineless margins and lobes, a feature directly reflected in its specific epithet. Its monumental inflorescences, shaped as long, dense spikes bearing tubular white flowers with purple hues, hold a legendary historical importance, being the exact botanical model that inspired the Corinthian capital decorations in ancient Greek and Roman architecture.
• Acanthus montanus — A species of evergreen perennial subshrub with partially woody bases, belonging to the Acanthus genus and Acanthaceae family, native to the tropical rainforests and shaded mountainous areas of West and Central Africa. It is distinguished by its large, deeply lobed, and heavily undulated leaves, whose margins are armed with sharp, rigid spines. Its inflorescences are spectacular erect terminal spikes made of white, pale pink, or light lilac tubular flowers, valued in horticulture for its exotic and sculptural appearance.
• Acanthus leaves — The plural form of the masculine noun 'acant'; it designates the ensemble of sculpted or painted ornamental elements that reproduce or stylize the leaves of the Mediterranean Acanthus plant. These decorative foliage reliefs are fundamental elements in the composition of Corinthian and Composite capitals in classical Greco-Roman architecture, repeated symmetrically and in tiers to create a dynamic visual effect of a natural crown.
• Aquarist — A person passionate about aquaristics, who engages in the breeding, studying, and collecting of fish, plants, and other aquatic organisms in aquariums; as an adjective, it refers to elements or activities specific to this hobby. This specialist or amateur possesses structural knowledge of water biochemistry, species compatibility, and the ecology of captive miniature ecosystems to ensure fauna survival.
• Aegisthus — A tragic figure in Greek mythology, the adulterous son of Thyestes and his own daughter Pelopia, born as an instrument of bloody vengeance within the cursed house of the Pelopidae. He is celebrated as the lover of Clytemnestra, with whom he plotted to assassinate King Agamemnon upon his return from the Trojan War, usurping the throne of Mycenae until he was slain by Orestes in an act of filial retribution.
• Ailurophile — A person who manifests a special, sometimes passionate or exaggerated love, sympathy, or attraction towards cats and other felines; pertaining to aelurophilia or specific to people who adore these animals. In medical or psychological contexts, the term describes an individual who centers their lifestyle or personal interest around the care and study of felids.
• Ailurophile — A woman who loves cats in a special or passionate way; the feminine form of the term aelurofil. As an adjective, it describes an entity, manifestation, community, or feminine attitude closely related to the structural passion for caring for, protecting, and collecting feline-themed decorative items.
• Air plant — Flower of the air; a term used as a specific epithet or common name for various epiphytic plant species, particularly within the Tillandsia genus (family Bromeliaceae), remarkable for their structural capacity to live suspended without soil, absorbing water and nutrients directly from atmospheric humidity through specialized hairs called trichomes.
• Aerophilatelist — A person or collector specialized in aerophilately; a specialist passionate about gathering, studying, classifying, and evaluating airmail stamps, flight postmarks, and postal documents that were actually transported by air via airplanes, helicopters, or airships.
• Aeschynanthus — A genus of perennial tropical herbaceous or subshrubby epiphytic or lithophytic plants belonging to the Gesneriaceae family, native to the humid forests of Southeast Asia. These plants are structurally characterized by pendulous stems, fleshy opposite leaves, and tubular flowers, often intense red, protected at the base by a dark tubular calyx resembling a lipstick tube, which is why they are popularly cultivated as hanging decorative plants.
• Aeschynanthus boschianus — Scientific name of a perennial epiphytic lipstick plant species from the Aeschynanthus genus, native to Java and neighboring regions, characterized by oval, glossy, slightly serrated leaves and bright red flowers emerging from a dark purple calyx. The plant is widely used in indoor horticulture as an ornamental greenhouse species, standing out due to its increased structural resistance to climate variations in apartments.
• Aeschynanthus lobbianus — Scientific name of a perennial epiphytic lipstick plant species from the Aeschynanthus genus, native to the tropical rainforests of Southeast Asia, structurally recognized by small, oval, dark green leaves and scarlet tubular flowers emerging from a long, tubular, dark purple-black, heavily pubescent calyx. This variety is extensively cultivated in hanging baskets due to the dramatic ornamental appearance of its inflorescences.
• Aeschynanthus pulcher — Scientific name of a perennial epiphytic lipstick plant species from the Aeschynanthus genus, native to Malaysia and Java, structurally characterized by ovate, smooth, bright green leaves with slightly purple margins and scarlet-red tubular flowers with a yellow throat, emerging from a short, greenish or purple, often glabrous calyx. The species is highly valued in interior landscape design for the elegance and vibrant coloring of its flowers.
• Aeschynanthus speciosus — Scientific name of a perennial epiphytic lipstick plant species from the Aeschynanthus genus, native to the tropical rainforests of Malaysia, Indonesia, and Thailand, considered one of the most spectacular in the genus. It is structurally recognized by large, lanceolate leaves grouped in whorls, and by huge terminal clusters of curved tubular flowers, up to ten centimeters long, bright orange with a yellow throat and red borders, extensively cultivated for their ornamental value.
