Stenocactus vaupelianus (Syn: Stenocactus albatus)

The first one up is Stenocactus vaupelianus, also known as Echinofossulocactus vaupelianus or Stenocactus albatus. It came to us labeled as Echinofossulocactus albatus. For the collector, the "albatus" moniker is probably the best to use, but scientifically it probably doesn't rate specific status - or at least that's the current reasoning. But as I say, as a collector it doesn't really matter too much. Beauties aren't they? (By the way, the currently accepted genus name is Stenocactus.)
