Gymnocalycium doppianum and Rebutia albipilosa

It got warm today. And though it's supposed to cool off for a few days, the forecast is for hot this weekend, maybe even reaching 90F. This is not normal here in May, but all I can tell you is that the cacti are loving it...

and so am I. I've had enough of cold and wet. Here we have two plants which are celebrating the warm weather in fine fashion: Gymnocalycium andreae v. doppianum (Syn: Gymnocalycium doppianum) at the top and Rebutia albipilosa at the bottom.
