I was recently at the Naples Zoo and they have a plant labeled Rose Mound. Latin name is listed as Dombeya acutangula 'seminole'. That's exactly how they have it. The single quotes would make me think cultivar, but then they don't capitalize the name. And looking at the entries in the database got me more confused. Then, I tried Google and it seems that some people list seminole as the species name which seems odd. Help is much appreciated!
