degrees, and enjoy a relatively warmer climate, though by no means a warm one. In 

 Kerguelen Island it is very abundant. The specimens brought from Marion Island by 

 Mr Moseley are dwarf — five to seven inches high ; and the seed-vessels are only very 

 slightly hairy, and about a third of an inch long. 



Pringlea antiscorbutica is the only species of the genus, which is a very distinct one 

 in habit, though closely allied in structure to the northern Cochlearia. 



[The Cerastium mentioned by Mr Moseley (Journ. Linn. Soc. Loud., xiv. p. 387) 

 does not appear to have been dried, probably because it was regarded as a certainly intro- 

 duced plant.]

Marion Island. Moseley. 



As here limited, this species inhabits the Crozets, Kerguelen Island, New Zealand, 

 Macquarie Island, Fnegia, and the Falklands. 



The flowers appear to be functionally unisexual, and to exhibit differences in the rela- 

 tive length of the stamens and other parts. The characters upon which Accena affinis 

 was founded depending upon mere sexual differences, Professor Oliver reduced the species. 



Most of the New Zealand specimens are altogether smaller, and have smaller leaves 

 than those from the islands of the South Indian Oceau and from America, but the 

 Macquarie Island plant is equally robust.
