to the short dichotomous branches of F. chondro'phyUus.''' The Antipodes and 

 Snares specimens that I have possess the long narrow sword-Hke receptacles that 

 are supposed to be characteristic of F. gladiolus, but which I think are merely typical 

 of a state of the species. All things considered, it seems better to use the first 

 specific name given to the original plant of the genus.

Auckland Islands ; Hooker. (Australasia.) 



In the " Pflanzenf amihen " of Engler and Prantl (Algae, p. 286) the genus Lands- 

 burgia is recorded from the Auckland Islands, on what authority I do not know. 

 As I have not found L. quercifolia (Harvey) south of Banks Peninsula^ it seems 

 scarcely probable that it should be found so far south as the Auckland Islands.
