Roystonea regia, or Royal Palm

Below, royal palms, Roystonea regia, formerly R. elata, line a street in Oahu.  That's a bit of Diamond Head you see in the left background.

After you start to see the differences among palm species, you begin to understand the subtle choices you can make in plant selection.  Royal palms, with their stout upright trunks, create a much more formal setting than a looser, arching coconut palm.  The austerity of this look is enhanced when you consider the regularly-occurring smooth rings that line the trunk.

In most cases, palms like this are maintained and the dead fronds and fruits are removed.  The plant has a close association with bats in its native range of Cuba/northern Caribbean, Florida and Mexico.  The pinnately compound leaves have fine, thin leaflets which create a softer texture than say, the foxtail palm.
