Here is your call.

There are very few epiphytes in desert climates, they exist, but
they are rare. Wet climates produce many more species and numbers
of epiphytes.

This makes sense, because epiphytes require rain and moisture from
the air. Lacking roots can be a problem therefore.

Unless there are epiphitic cacti, growing on other cacti.
Which in turn support yet another smaller epiphitic cactus.... and
so on ad infinitum.

This humble writer challenges
Cereus.Epiphytum.XeroCactumHangAboutum to give a pictorial
example.........




He doesn't seem to be responding to his call, maybe there isn't
anyone home.

Most of the epiphytic cacti grow in the tropics, in rainforest or
near rainforest conditions.
