The first one looks like little snarling, excited monsters to me. The last one is darker than in the photo and has a very fine edge of white. That's why I bought them. The middle one is ... well, another colorful Dendrobium!
Thanks for the compliments. I'm fertilizing the Botanical Garden's plants more regularly, and should be getting some interesting blooms eventually. I need a better camera! Since I always like to add a photo to every post, another photo!
Say, if anyone knows of affordable "antelope" dendrobiums, please let me know. I found one online vendor, but the plants started at $250.00, ouch!
