Ok for those who know what i am speaking of:
Are you a splitter or a lumper?
Personally I am a lumper unless there is an obvious reason. Especially i know there is tooooooo much splitting going on in the Cactus Family.
If you ever have the time or are curious check out how many Cereus divisions there are. Cereus are the majority of columnar cactus, but also includes epiphytes.
