Hi, Doc
The barrel cactus I see blooming on some of our trips is almost identical, 'cept the blossoms seem to have just a touch more red. And, IF it's been a more moist year than usual, the thorns sometimes take on a brighter yellowish tint than normal (in dry years they can be very dark.) Minor stuff, though, so I'm gonna say "dem's the ones!"
Thanks again!
