Attalea crassispatha (Attalea crassispatha)
Description
Attalea crassispatha has a single stem which grows up to 20 metres (66 ft) tall. The stem is grey, up to 35 centimetres (14 in) in diameter, and can be columnar, or slightly swollen at the base of the middle of the stem. Individuals bear 15 to 19 pinnately compound leaves—leaves in which rows of leaflets emerge on either side of the axis of the leaf in a feather-like or fern-like pattern—with 127 to 165 pairs of leaflets. Leaves consist of a leaf sheath which wraps around the trunk, a rachis, from which the leaflets emerge, and a petiole, which connects the leaf sheath with the rachis. The leaf sheath is open (it does not wrap completely around the stem); when the leaf is shed, the leaf sheath detached cleanly from the stem. The sheath and petiole combined are 1.3 to 1.35 m (4 ft 3 in to 4 ft 5 in) long, while the rachis is 3.2 to 4 m (10 to 13 ft) long.
