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] Phylogenetic relationships between the four genera are unresolved.[3]

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 Areceae. 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).

gollark: I'm already tracing your IP. Muahahahaha.

gollark: WHAT THEN?

gollark: What if they navigate the SSL webscale node? Or activate an open-source HTTP platform?

gollark: You can use proof of stake, which is somewhat terrible, or proof of my private key signed this, which probably breaks a lot of the incentives but who cares.
