The Royal Botanic Gardens Kew Plant List and Taxonomic Index

• Alangium — A genus of flowering plants in the family Cornaceae (or Alangiaceae in alternative higher classifications), comprising species of small to medium-sized trees and shrubs native to tropical and subtropical regions across Asia, Africa, and Australia. These plants exhibit a unique structural feature of long, recurved petals and are historically recognized in traditional Chinese and Ayurvedic medicine for the complex alkaloids contained within their roots and bark, used empirically to treat rheumatic and dermatological disorders.
• Arthropodium — A genus of perennial herbaceous plants in the family Asparagaceae (subfamily Lomandroideae), native primarily to the Southern Hemisphere, particularly Australia, New Zealand, New Caledonia, and Madagascar. These plants are structurally characterized by tuberous roots or short rhizomes, linear leaves, and delicate flowers arranged in panicle inflorescences, featuring stamen filaments covered with fine hairs, from which its etymological name derives.
