This holds surely true in most cases. However I startet to experiment 
with GA a few years ago and it was possible to induce long shoots in 
Nepenthes. So it was possible to make cuttings from plants which 
usually grew as rosettes.

This sounds extremely interesting to me. Could you mail a copy of 
this comment to me and give me the e-mail adress of the orchid group.
Does anybody know of any papers dealing on long-term storage of 
pollen?
