Gymnocalycium mostii (G. valnicekianum)

We received this cactus, from Cordoba Province in Argentina, under the name Gymnocalycium valnicekianum, but it has now been lumped into G. mostii. The large flowers look dirty-white when they are closed, but they are stunning when open, the pearly white of the petals fading to red at the center, with a tuft of white stamens within.
