Casurarina eqiosetifolia (Australian Pine) is a species that I had not seen before ever as a bonsai and I have yet to see one in the UK either. We came across this species at the BCI convention in China and it certainly made an impression. For details on this species visit: Wigerts Bonsai

There is another extensive article on the BCI website which is worth a read and I think it was also a feature in the BCI magazine too.
