BOTANICAL EXPLORATION OF THE CHATHAM ISLANDS. 11 
Buchanan also published many observations on botanical matters, 
and wrote a work on the grasses of New Zealand, in which life- 
size figures of all the species of that family, as then known, are 
given. He also paid a short visit to Campbell Island. 
In 1863 Mr. Henry H. Travers, who is still an industrious collector 
of New Zealand plants, made a botanical exploration of the Chatham 
Islands, the flora of which was unknown, save for a few species col- 
lected in 1840 by Dieffenbach. Travers, who stayed some months 
on the islands, with Pitt Island as his headquarters, made a most 
valuable collection of the plants. This was examined by Baron 
von Mueller, who published the results in his “ Vegetation of the 
Chatham Islands” (1864). Mr. F. A. D. Cox, who resided in 
Chatham Island for many years, spent much of his leisure in 
studying the plants of that island, and brought to light many new 
facts regarding their distribution and habits. He also collected 
assiduously, sending much valuable material to Kirk, Cheeseman, 
and the author. In his honour Cheeseman founded the genus Cozella. 
The publication of Hooker’s Handbook brings us to what may 
be called the modern stage of New Zealand botany. Here the late 
Mr. Thomas Kirk and Mr. T. F. Cheeseman stand foremost. For 
many years Kirk held the position of leader of botanical thought 
in New Zealand. He was not only an industrious collector, visiting 
many parts of both Islands of New Zealand as well as the sub- 
antarctic islands, but a prolific writer, as is proved by the 140 
papers to his credit in the “Transactions of the New Zealand 
Institute,’ to say nothing of publications elsewhere. He also wrote 
the “‘ Forest Flora of New Zealand,” which is the classic so far as 
New Zealand trees are concerned. At the time of his lamented 
death he was engaged on a new Flora of New Zealand, which, to 
the great loss of science, he did not live to complete. Fortunately, 
one-half was finished, and, although it lacked the correcting hand of 
its author, it will stand as one of the foremost publications on 
New Zealand floristic botany. 
Mr. T. F. Cheeseman’s botanical researches began in the early 
~ seventies’ of the last century, his first paper being published in 
1873. Since that time he has been a most ardent and successful 
investigator of the New Zealand flora. Were his shorter papers 
alone to be considered he would always rank as one of the 
Dominion’s foremost botanists. But in 1906 his “ Manual of the
