The erect to horizontal fronds are up to 4 m (13 ft) long, and are slightly rotated around the long axis. The massive branched inflorescence is up to 1.5 m (5 ft) long and bears white flowers. When ripe, the fruit is red and 13–15 mm (0.5–0.6 in) in length. The flowers closely resemble those of A. alexandrae . [4] [5]
