Echinopsis - jaki gatunek?

[morajko]

Mam kaktusa, ale nie wiem jakiego jest gatunku. Wydaje mi się, że Echinopsis oxygona lub Echinopsis eyriesii.

Proszę o pomoc w rozpoznaniu.

Wygląda, że to rzeczywiście Echinopsis oxygona.

W książce Edward F. Anderson. The cactus family. Portland 2001. ISBN 0-88192-498-9 znalazłem takie opisy:
