Royal palm (Roystonea regia).—E.R. Degginger/EB Inc.

Any of about 2,800 species of flowering, subtropical trees, shrubs, and vines that make up the family Arecaceae (or Palmae). Many are economically important. Palms furnish food, shelter, clothing, timber, fuel, building materials, fibres, starch, oils, waxes, and wines for local populations in the tropics. Many species have very limited ranges; some grow only on single islands. The fast growth and many by-products of palms make exploitation of the rainforest appealing to agribusiness. The usually tall, unbranched, columnar trunk is crowned by a tuft of large, pleated, fan- or feather-shaped leaves, with often prickly petioles (leafstalks), the bases of which remain after leaves drop, often covering the trunk. Trunk height and diameter, leaf length, and seed size vary greatly. Small flowers are produced in large clusters. Among the most important palms are the sugar palm (Arenga pinnata, or A. saccharifera), coconut palm, date palm, and cabbage palmetto.
