Flora of China and Royal Botanic Gardens Kew Botanical Database
- 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.
- 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.
- Adiantum aethiopicum — A species of terrestrial, perennial fern in the Pteridaceae family, natively distributed across Africa, Australia, New Zealand, and islands in the Indian Ocean. This plant is structurally characterized by creeping rhizomes, slender, glossy, dark brown to black stems, and delicate, compound fronds made of small, rounded or fan-shaped pinnules, being cultivated internationally as an ornamental plant due to its aesthetic foliage.
- Adiantum formosum — A species of large terrestrial fern in the Pteridaceae family, native to the rainforests and moist forests of eastern Australia and New Zealand. This plant develops structurally through deep, creeping rhizomes and produces finely divided, compound fronds that can reach heights of over one meter, supported by long, rigid, glossy-black petioles, cultivated ornamentally for its lush appearance.
- Adiantum veitchianum — A rare species of perennial fern belonging to the Pteridaceae family, native to the mountainous regions and shaded forests of China. This plant is structurally distinguished by its delicate fronds, often arranged on slender, rigid, and glossy dark-brown stems, and by small, triangular-ovate pinnules, being cultivated exclusively in botanical gardens or private collections due to its taxonomic rarity.
- Antennaria parvifolia — A species of perennial herbaceous plant in the Asteraceae family, native to the mountainous and arid regions of North America, commonly known as 'small-leaf pussytoes'. This stoloniferous plant is adapted to drought and poor soils, forming low, dense vegetative mats characterized by small, spatulate basal leaves covered with a dense woolly tomentum, and whitish or pinkish flower heads.
- Arundinaria hindsii — The scientific name of an erect bamboo species native to East Asia (currently known taxonomically as Pleioblastus hindsii). This perennial plant from the Poaceae family is structurally characterized by slender, rigid, dark green culms that grow densely and compactly, frequently used in landscape architecture for creating resilient natural screens and ornamental hedges.
- Asarum virginicum — A species of evergreen perennial herbaceous plant native to the southeastern United States, historically known in taxonomy under this academic name and currently classified as Hexastylis virginica. Characterized structurally by its persistent, heart-shaped leaves with a striking mottled pattern and unique flowers hidden close to the ground, it is appreciated in niche horticulture for its shade tolerance and decorative groundcover qualities.
- Asplenium decorum — An exotic fern species in the genus Asplenium, found in isolated tropical or island regions (such as certain zones within Pacific Ocean archipelagos). This plant is characterized by a compact growth habit and fronds with an extremely ordered, elegant, and symmetrical geometry, a refined structural appearance from which the specific epithet 'decorum' (decorative / elegant) originates. It is a rare species, studied primarily in niche botanical monographs.
