• Abrus — (Botany) A genus of climbing plants in the family Fabaceae (Leguminosae), native to tropical and subtropical regions worldwide, characterized by pinnate leaves and pods containing spherical seeds that are often intensely colored and highly toxic due to their abrin content.
• Acanthaceae — The large botanical family of dicotyledonous plants (Acanthaceae) within the Lamiales order, comprising hundreds of genera and thousands of species of herbs, shrubs, and vines, primarily distributed across tropical and subtropical global regions. Morphologically, these plants are characterized by simple, opposite leaves, spike- or raceme-type inflorescences equipped with large, often intensely colored bracts, and dehiscent capsule fruits remarkable for their explosive seed expulsion mechanism.
• Acrocomia — A genus of monocotyledonous plants in the palm family (Arecaceae), native to tropical and subtropical regions of Central and South America. These palms are characterized by massive trunks covered with sharp spines and dense crowns of pinnate leaves.
• Aechmea miniata — A species of perennial epiphytic plant in the family Bromeliaceae, native to the humid tropical forests of Brazil, remarkable for its glossy deep-green leaves, often tinged with purple on the underside of the blade. It develops an erect, paniculate inflorescence composed of a bright red scape bearing globose red berries of a minium (red lead) hue and small flowers with blue or translucent petals.
• Aechmea paniculata — An exotic species of perennial herbaceous plant in the genus Aechmea, native to the densely forested rainforests of South America, remarkable for its complex, heavily branched paniculate inflorescence. Its foliar rosette, composed of rigid leaves with serrated margins, forms a deep central reservoir destined for storing rainwater and absorbing dissolved nutrients through specialized cellular scales.
• Allamanda — A genus of flowering plants in the family Apocynaceae, native to the tropical regions of Central and South America. It comprises species of climbing shrubs and vigorous vines, widely cultivated in warm climates or greenhouses as ornamental plants due to their glossy foliage and spectacular, large, usually yellow or purple funnel-shaped flowers.
• Alloplectus — A genus of plants in the family Gesneriaceae, native to the neotropical regions of Central and South America, particularly in humid, high-altitude forested areas. It comprises small shrubs, vines, or epiphytic plants, recognized by their opposite, often velvety leaves, and tubular flowers protected by large, intensely colored bracts in shades of red, yellow, or orange, occasionally cultivated by collectors in warm greenhouses.
• Green velvet alocasia — A tropical plant species endemic to the island of Luzon (Philippines), belonging to the Araceae family, globally renowned for its velvety, deep dark green leaves, striking white-cream veins. Commonly known as Alocasia 'Frydek' (which usually designates the nursery-grown cultivar), this collector's plant features arrow-shaped leaves with elegantly wavy margins, highly prized for its exceptional ornamental value.
• Alternanthera — A major genus of herbaceous plants or shrubs in the family Amaranthaceae, primarily native to tropical and subtropical regions of the Americas; it comprises numerous terrestrial and aquatic species, highly valued in horticulture and aquascaping for their spectacular, vividly colored decorative foliage in shades of red, purple, pink, or yellow.
• 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.
• Anthurium andreanum — The scientific name for the painter's palette or flamingo flower, a tropical perennial in the family Araceae native to Colombia and Ecuador, famous for its heart-shaped glossy leaves and bright red waxy spathes surrounding a yellow spadix.
• Apocynaceae — A family of higher dicotyledonous plants, often tropical or subtropical, characterized by the presence of a white latex, regular hermaphrodite flowers, and follicle-type fruits; a plant belonging to this family. Many species possess high pharmacological importance due to their rich content of alkaloids and cardiotonic glycosides, while some are used ornamentally.
• Asplenium nidus — A popular species of epiphytic fern in the Aspleniaceae family, native to tropical regions of Asia, Africa, and Oceania, commonly known as the bird's-nest fern. It is characterized by large, entire, lance-shaped fronds of a glossy light green, featuring a prominent dark midrib; the fronds grow arranged in a compact central rosette reminiscent of a nest, possessing the biological capacity to collect rainwater and organic matter falling from trees.
• Asystasia — A genus of flowering plants in the family Acanthaceae, containing approximately 70 species native to tropical and subtropical regions of Africa, Asia, and Australia. Many species, such as Asystasia gangetica, are cultivated as ornamental plants due to their attractive funnel-shaped flowers, but can become invasive in sensitive habitats.
