[NHCOLL-L:971] preserving Araucaria cones

[Chris.Ecroyd at ForestResearch.co.nz]

I am very interested in any suggestions on how to prevent Araucaria
bidwilli cones from disintegrating.  I have tried soaking them in
alcohol/50% glycerol and I have tried drying them.  I have had very good
results with the alcohol/50% glycerol method on other cones especially
Abies & Agathis but not Araucaria cones.  Would freeze-drying work?
