Hey I thought we put all stuff on gymno calicium in here
there is some discussion in the following links
http://www.shaman-australis.com/forum/index.php?showtopic=29996&st=300
So
How about some photos?
G.baldianum
I regarded this a hybrid [seed was gifted from a friend, couple years ago] but now I see this really looks like
G. gibbosum var. platensis
this specimen above is a degrafted and rooted specimen
also check a still grafted biggy speciman
... next to a grafted coryphantha elaphadidens.
