Archontophoenix myolaensis

This species of Archontophoenix is native to a small area in the mountainous region west of Cairns in N.W. Queensland, found in a few locations in gallery forests following rivers. It is similar to the more common Archontophoenix cunninghamiana, with a slightly smaller size, a bluer crownshaft and some other minor differences. It is indeed the rarest in the wild and the least common in cultivation of the whole genus, while it is fast and easy like its relatives.
