I'm gonna go ahead and bump all of these down.
In case anyone comes along later and wants to see all of them, here are the links:
They're all tropical plants, of course. Did you post any of them on a tropical plants forum?
Nope, I'll have to check it out. Don't think I ever even noticed that forum. Of course, people from the tropics may be less impressed. When I go to Hawaii, I find people there are more interested in temperate area plants. Just like many of us, they get bored with what's in their "backyard".
The first one,Pittosporum kauaiense, looks a lot like a SCHEFFLERA ACTINPHYLLA, or Umbrella tree. I have a bonsai Umbrella tree that is 15+ years old. Beautiful trees!
