It was found under a rock or in the topsoil by my stepdaughter. It was found at the edge of some farmland/pasture very near a patch of regenerating forest. Sorry about the quality of the pictures! I don't think it will be able to be identified to species from them, but anything better than Family would be appreciated!
Seems to have seeded beneath a Tarata / Lemonwood on Lincoln Uni Campus
sneaking in and spreading into the park from under a fence!
