This one is a very interesting multihybrid cross between two different genera. ALTENA is a Hartmut Kellner cross with the parents Lobivia DESSAU x T, purpureopilosus and a hybrid with Lobivia densispina. ALTENA basically got the extremely contrast rich flower of DESSAU and the precious flower shape of T.purpureopilosus. And the father is a Lobivia/Echinopsis densispina hybrid with a beautiful yellow/white throat.
