Diagnostic Features

This is not just a large form of Ulota lutea, but a distinct variety that forms tufts rather than cushions and has a shorter seta, smaller capsules and shorter endostome teeth.

Habitat and Distribution

Endemic to Tasmania. Dixon’s notes on the isotype packet in HO state that “I have not seen this species so robust before but I have N.Z. & Tasmanian specimens quite approximating to it. H.N.Dixon 9 Aug. 1921.” However, var. robusta is a Tasmanian endemic, and it does not occur in New Zealand.
