A small genus of 4 species, 3 of which are Asiatic or Australasian, the fourth 
South American. It is closely allied to Cotula, but differs in the inflorescence 
and in the tubular corollas of the female florets. The New Zealand species 
extends to Australia, the Pacific islands, and eastern tropical Asia.
