RE: Australian ferns

Hi All

Seems a lot of comment on this one, but we need to be ultra realistic, you
can't get away from the fact that with Huperzia dalhousianum is especially
unique, that it is now and has been on the endangerd list for some time because
of its removal from the wild over the past say 100 years or so. 

Then add to the equasion, it grows in a very specialised natural habitat,
so if it were collected, it could not be kept growing because 'the habitat
could never ever be recreated'.

It is generally known from a few now deceased expert growers, this has all
been tried many years before their time, without success.

As for being grown from spore, even with the other species of Huperzia, these
have all proved so far, to be impossible to grow from spore. So you can cross
that off the list as well.

As Peter said in an earlier email,it has been made illegal to 'even grow
it' in an effort to stop anyone from taking a plant from the wild. In this
case and a few others, legislation has been appropritely correct.

I must say also, Peter Bostock is a hands on Botanist who is well respected
in the Australian plant communities for his involvement with the former SGAP
(Society for growing Australian Plants) now called, Australian Plants and
is also their Leader of the Queensland Fern Study Group.
