Hello!
I'm not great with S. American cacti, and I have three that I think I know the genus of, but am not sure of the species. Any help would be appreciated.
1. An Oreocereus. Maybe O. trollii?
2. An Espostoa. I think it might be either E. lanata or E. melanostele, but neither of them seem 100% right.
3. Rebutia. Maybe minuscula, but I haven't seen pics of minuscula with yellow flowers.
Thanks everyone!

Re: Some South American Cacti
The first definitely looks like O. trollii.
I lean toward E. melanostele for the second one, not real sure.
R. minuscula can have yellow flowers, looks like the correct ID to me.

The yellow flowered Rebutia is Rebutia marsoneri in one of its forms. This is sometimes reduced to a variety under R. minuscula as Spence says.
