Tristan da Cunha. Thouars ; Carmichael. Inacessible and Nightingale Islands. 

 Moseley. 



Eudemic in the group. 



Like the majority of the undoubtedly indigenous plants, this occurs on all the islands 

 of the group. It is very different from Nertera depressa, being much larger in all its 

 parts ; and it is also distinct from the four or five other species inhabiting Australia, New 

 Zealand, Java, the Philippine Islands, and South America.

 common New Zealand plant, as a synonym of this.
