The orchids don't have any idea of what we are calling them and so far as I know no orchid plant has EVER been an author on a published recombination. It is the ORCHID BOTANISTS who are doing all the changing. For that matter, the plants don't think of themselves as species. The pollinators aren't careful to fly only to flowers humans would consider of the same species. "Species" is a concept we made up to try and name a concept we observed. By the way, at the upcoming Convention of the Cactus and Succulent Society of America in Scottsdale, one of the speakers will be Chuck Hanson of Arid Lands Greenhouses talking about succulent orchids from Madagascar. Of course, there will be an enormous plant sale, open to the public free with no need to register for the Convention. (The plants aren't free.) Some of these little Oeceoclades orchids grow in leaf litter with buried pseudobulbs and exposed leaves, so they might be considered bulbous or hypogaeal. http://www.cssainc.org/convent.html Leo Martin Phoenix Arizona USA
