The Echinopsis is a Echinopsis subdenudata 'Dominoes' (depending on your view on taxonomy you might like to replace subdenudata with ancistrophora. The 'Dominoes' or ('Dominos'?) is just a name some growers use for a selection with big, white areoles that looks like the dots on dominos. Nice flowers.

Thanks much for the info. With the info I had I could not find it on the net.

Here is your basic e. subdenudata in flower. Subdenudata might mean "cactus obscured by flowers"...or it might not. Congrats on branching out from just jades.

Nice photos! Thanks for posting. Looks like I'll enjoy it especially when it blooms. The cactus and succulents are slowly replacing my African Violet collection. Only have room for so many plants and find the C & S are easier to manage when I travel for any length of time. At one point I had over 300 African Violets.

Subdenudata means something like "almost stripped bare". I don't know what it refers to, maybe the short spines.
