The total number of species collected is thus thirty-two, of which three are naturalised. 
This shows an increase of no less than fourteen on Dr. Scott’s list, proving that Mr. 
Hamilton evidently made full use of the limited time that he was able to spend on the 
island. The most important result derived from his visit, however, was the totally 
unexpected discovery of three new species of grasses— Deschampsia penicillata 
T. Kirk, Poa Hamiltoni T. Kirk, and Festuca contracta T. Kirk. Up to that time, no 
one had even suspected that Macquarie Island had an endemic flora of its own, and 
the establishment of that fact not only marked an important advance, but also com¬ 
pelled a re-arrangement of all previous views on the history and development of the 
vegetation of the Island. 
After Mr. A. Hamilton’s visit, no information of any consequence bearing on the 
vegetation of the island was obtained for many years. In November, 1901, Captain 
Scott, in the “ Discovery,” landed on the eastern side to collect specimens, but his stay 
was limited to a few hours. In 1909, Captain J. K. Davis, then associated with the 
Shackelton expedition, and in command of the auxiliary vessel “ Nimrod,” made a 
similar brief visit. 
On 12th December, 1911, the Australasian Antarctic Expedition’s vessel 
“ Aurora ” arrived off the north end of the island. In the introductory notes to this 
memoir, I have mentioned the reasons that actuated Sir Douglas Mawson in deciding to 
establish a subsidiary base on Macquarie Island, and in leaving a party thereon. It 
is now necessary to say a few words respecting the constitution of the party, and the 
botanical work that it has performed. The explorers were five in number. G. F. 
Ainsworth was selected as leader, and acted as meteorologist ; H. Hamilton was
