What is the tradescantine plant here growing among the Austroblechnum penna-marina? Help anybody?

Graeme, I don't have an answer but something about the photo makes me think 'grass'. Have a closer look and see if the leaves are on sheaths and if so get a close up of the leaf and of the ligule where the leaf joins the sheath. By the way I like that 'tradescantine'

Oplismenus imbecillus (a grass - well done Graeme)

Thanks troops. Much appreciated. You beat me to the close-up photo I was going to post.

Thanks Mike
