THE VASCULAR FLORA OF MACQUARIE ISLAND.—CHEESEMAN. 
33 
Mr. H. Hamilton is the first to gather this species on Macquarie Island, where it 
seems to be rare, for he remarks on his labels that it was only seen in the locality quoted 
above. His specimens correspond very well with others that I have examined from 
Auckland Islands and the Snares. It has also been recorded from Campbell Island 
and Antipodes Island. In New Zealand it is sparingly found near the coast from Queen 
Charlotte Sound southwards to Foveaux Straits. In South America it was collected by 
the illustrious Darwin at Cape Tres Montes, to the south of the Chonos Archipelago; and 
Sir J. I). Hooker found it abundant on the Falkland Islands ; but so far as I am aware, 
it has not been recorded in the intervening districts of Patagonia and Fuegia. It is 
also unknown in the South Georgia and Kerguelen groups. C. trifida is the only species 
of Carex confined to temperate South America and the New Zealand area, unless 
Kukenthal is correct in identifying a Chatham Island plant with the South American 
C. Darwinii .

Macquarie Island :—Common all over the island, in swampy places and on the 
hillsides. A. Hamilton (1894); H. Hamilton (1912-1913). 
This is a widely distributed species. It is found in southern Chili, Fuegia, and 
the Falkland Islands ; and has also been recorded from Kerguelen Island, Marion 
Island, and Heard Island, but curiously enough has not yet been detected in South 
Georgia. It is abundant in the Subantarctic Islands of New Zealand ; and has also 
been gathered in a few localities in New Zealand proper. It is thus a true circumpolar 
species, and its wide distribution, together with that of a few other species, must be 
taken into account in considering the origin and development of the southern circum¬ 
polar flora generally. 
It is somewhat remarkable that Dr. Scott did not collect A. magellanica. on 
Macquarie Island; for both the Hamiltons assure me that it is abundant thereon. The 
numerous specimens collected by H. Hamilton prove that it varies greatly in size, as 
also in the length of the awn, and the degree of development of the palea.
