Caryota urens, Rhopalostylis sapida, Rhopalostylis baueri, Washintonia robusta, Archontophoenix cunninghamia and Archontophoenix alexandre

Love all the tree names ! I looked up Shaving Brush Palm. That's the row of trees along the lower right half of the photo ? Yes ? I looked up Nikau palm and that is similar shape ? :o)

Could you explain, please, which is which left to right. LOL. Thanks.

Terratoonie:

It is really difficult to see the difference between the Nikau and Shaving Brush palms in this photo. The Shaving Brush palm has a more round/bulbous crownshaft - Nikau Palms have a longer, smoother less bulbous crownshaft. Also, the leaflets are thinner on the Shaving Brush Palm.

In order to see what I mean I will have to take a close up of the two palms and post them separately. There's a huge difference when viewed up close plus the Nikau Palm grows much taller up to 50 feet/ 15 meters tall and has larger fronds overall.

To make things more confusing...there could be an occasional Rhopalostylis cheesmanii - Kermadec Palm (from Norfolk Island) in this collection of palms which looks closer to Rhopalostylis baueri (I know - it's like opening a can of worms!) LOL.

Wow, that does sound more complicated than I was anticipating.
Thank you for the detailed answer. :o)

Terratoonie,

You're welcome!
