Naked Calyx Cactus
Nice cactus! I wonder what the flower will look like?
Gymnocalycium eurypleurum was only recently described, in 1979. Before that was it unknown? I don’t know. But it’s from Paraguay, so maybe it was known to some for years and only recently discovered by others who chose to publish its description. I should look it up in my catalog of the Journals of Cactus Science. If only I had one of those.
