Archontophoenicinae

Archontophoenicinae is a botanical subtribe consisting of four genera of palms, namely Archontophoenix from Queensland and New South Wales and Actinokentia, Chambeyronia and Kentiopsis from New Caledonia.^[1][2]

Description

The palms in this subtribe are medium-sized palms, with well-developed, distinct crownshafts and strictly pinnate leaves with generally short and massive petioles. The inflorescences are branched to two or three orders, with the prophyll and penduncular bracts similar. The subtribe is homogenous compared to other subtribes of the Arecaea. All the genera have more than six stamens. The New Caledonian genera have distinctive leaf anatomy and may share a common ancestor (Uhl and Dransfield 1987:367).

Notes

1. ^ Some sources include the genus Mackeea in Archontophoenicinae. This is a synonym of Kentiopsis.
2. ^ Two other genera, Hedyscepe from Lord Howe Island and Rhopalostylis from Norfolk Island, Australia, and New Zealand (including the Kermadec Islands) were formerly included in this subtribe, but have now been separated out to form the subtribe Rhopalostylidinae (Dransfield, Uhl et al., 2005).
