This might seem a strange thing, but could it be a "well washed" Oreocereus celsianus? Fat and green, weak spines, but it seems to have some matted hair.

This plant has never had much hair, but it is quite small. In fact, it hasn't done much in the three months I've had it. Hopefully it grows well in the coming warm season, and becomes healthier, more identifiable.
