Thanks for the info Jeff. I'm lucky/happy to see the cycads but certainly don't know what they are. The ceratozamias were just everywhere. Never crossed into my mind that being pretty much (seemingly) continuously wide-spread that it would be several species. Do they naturally cross at all with that proximity? I'm sure they weren't actually contiguous or mixed colonies, but seems like there has to be some opportunity. There were so many that I was really amazed when I realized that they were cycads and not just big ferns.
I also saw many Agave dioonioides :P The grass that was around them when lit just right made them look just like dioons. I got a pretty good laugh out of it. I'm glad that I was able to crop the picture of the orchids to see what they were before too much fuss was made.
