Splendid South American trailing plants with smooth leaves and tubular bell-shaped yellow flowers. The best-known kinds are Hendersoni and grandiflora, the former having very large blooms. Others are nobilis, Schotti, Aubleti, Chelsoni, neriifolia (a bushy plant), and verti-cillata, all yellow flowered; while violacea is a rare species with violet-rose flowers. Allamandas are easily grown in sandy loam in a warm and moist house, and may be raised from cuttings of the young half-ripened shoots.
