Apart from the (Macarthur palms) , we have a couple of palms that are apparently somewhat uncommon, and I'm trying to identify them. They've grown to about 6-8 metres, and are in a clump like the Macarthur palm, though they don't bend outwards in the same way.
I also got some photos of the flowers, which attract bees
and the fruit which is a deep purple
Does anyone have any idea of what it is? Any help is welcome! Thanks to the commenter anthrome below, and to the helpful people at Palm Talk, our palm tree is confirmed as a aka Acai , apparently the palm hearts and berries are edible too! Gonna have to try that some time.
