A genus of 13 species, of which 1 occurs in the Falkland Islands, another in 
Patagonia, a third in Victoria, and the remaining 10 are endemic in New Zealand. 
The genus has been very carefully monographed by Domin in Engler’s Jahrbuch (vol. 40, 
pp: SEAS Ua: The following disposition of the species is mainly based on Domin’s 
work.
