    • Plant Morphology :
      Growth Form: A tall, solitary, fast-growing palm with large, stiff, feather-shaped leaves, exuding a graceful and elegant appearance.
      Trunk: Stem smooth, circularly marked with prominent leaf scars, light grey; trunk base usually swollen; crownshaft light green, but occasionally brownish.
      Foliage: Fronds pinnate, 2 to 3 m long, unarmed, dark green above and silvery-white beneath.
      [Others]: Flower: Inflorescences creamy white, arising below crownshaft. Fruit: Fruits round, 1 to 2 cm in diameter, bright red when ripen.
      Cultivation :
      Prefers full sun, but also tolerable to partial shade. It favours more water than most palms do and likes well draining soils. Able to be withstand indoors to some degree of tolerance. Propagate by seeds, which germinate readily in 4 to 8 weeks.
      Etymology :
      The genus epithet Archonotophoenix comes from the Greek as 'king' or 'chief', and 'date palm', and that all species in this genus share the common name king palm. The species epithet alexandrae honours Princess Alexandra of Denmark (1844 - 1925).
