Characteristics

A large palm. The trunk is whitish and 30 m tall. It is 50 cm across. The trunk is the same width throughout except for a bulge at the base. The leaves are pinnate and green. The leaves are 5-7 m long. They are flat at the bottom of the crown. This is because the leaflets are placed in one plane. There is a prominent green crown-shaft. It is 2 m long. The leaflets are light green and crowded along the midrib in 2 ranks on the same plane. The flower stalk comes out below the crown-shaft. It is over 1 m long and has many branches. The flowers are white or cream. The fruit are small, round and bright red to purplish black. They are 15-20 mm long by 8-10 mm wide.

To 40 m. and perhaps somewhat more in native forests, prominently bulged at base, usually more or less bulged also at the middle or above but in age becoming more uniform: leaves 3-7 m. long, 2 m. broad at middle, with 100 or more closely placed pinnae as much as 5 cm. broad, leaves with a flat look due to the simple arrangement of parts: spadix branches undulate or waved, at least when in cymba and after release: fruit oblong and usually somewhat curved, 15-20 mm. long, 9-10 mm. thick, purplish to black: note contrasts in key.
