To expand a bit on what Ron said.... Chamaedorea elegans Alsophila cooperi (Sphaeropteris cooperi),I believe. Pittosporum tobira HTH Chris
What about Chamaedorea seifrizii?? The flowers/seeds in the second photo would be consistent with C seifrizii as they are orange, C elegans are yellow, what do you guys reckon?? I just can't seem to focus in enough on the orange thing in photo 2 to confirm Ed
Pics 3/4 look to be Cyathea Cooperii (Alsophila Australis, Sphaeropteris Cooperii, yadda, yadda, yadda). I saw these planted everywhere when I was in San Diego last July!
