Author's notes

Seen at the base of a snow gum on the edge of the ski run just down from the Ginini Flats car park. I have added a band-aid to cover a wound which I believe unwise to show.

I think it is more likely to be G. surcula, based on where found. G. sesamoides not found above 1000m. Can't easily distinguish the two without digging it up!

Interesting. Out of the three gastrodias in your book, I decided this was the least likely. I suppose it can be hard when the plant hasn't flowered yet. Also, it is entirely likely that it has been dug up by now. During a school trip earlier that year, we noted just how much the feral pigs had churned up the ground.

Prior to flowering, the flower stem of S. sesamoides is nodding giving the appearance of a shepherd's crook. The tubers of Gastrodia are quite succulent and attractive to feral pigs which cause a lot of damage to montane swamps.
