Readily known by its lurid green colour, and broad epilose leaves, 

 narrowing towards the base. Mr. Waddell's specimen has minute globular 

 gonidia scattered over the upper surface of the leaf, not unlike those of 

 T. papulosa. The specific name latifolia is preoccupied by the union of 

 Desmatodon with this genus.
