XXXII HISTORY OF 
and the late Professor J. G. Aghard, while scattered memoirs relating to 
other orders of cryptogams have been published from time to time by 
Dr. Berggren himself. 
rom 1875 to the present time many important contributions to our 
knowledge of the flora of the colony have been made by Mr. D. Petrie, 
formerly Chief Inspector of Schools for Otago, and now holding a similar 
position in Auckland. During a residence of more than twenty years in 
Otago he sedulously investigated the vegetation of the eastern, central, and 
southern portions of the province, ascending many of the mountains, and 
forming large collections, especially of the rarer alpine and subalpine plants. 
Among the species added by him to the flora are Ranunculus Berggreni, 
Carmichaclia compacia and C. Petriei, Coprosma wirescens and C. Petriei, 
Olearia fragrantissima, Celmisia prorepens and. C. Petriet, Myosotis Goyent, 
Fetrachondra Hamilton, Veromca Petriei, Ourisia prorepens, &c. In com- 
pany with Mr. G. M. Thomson, he also visited Stewart Island, making several 
discoveries of interest, as Actinotus bellidioides, Liparophyllum Gunnit, Carex 
longiculmes, and Ehrharia Thomsoni. In 1895 Mr. Petrie published his 
“ List of Flowering-plants indigenous to Otago,” in which he catalogues the 
whole of the species, numbering over 760, observed by himself in Otago, 
giving at the same time particulars respecting the geographical and altitu- 
dinal range of the species. Altogether forty-four papers on botanical subjects 
are credited to Mr. Petrie in Mr. Hamilton’s bibliography of New Zealand 
botanical literature. 
Mr. G. M. Thomson, of Dunedin, has also done excellent service towards 
the elucidation of the botany of Otago. As already mentioned, he accom- 
panied Mr. Petrie in an exploration of Stewart Island, and has collected 
largely in the vicinity of Dunedin. Several papers on Otago plants have 
been contributed by him to the ‘“‘ Transactions of the New Zealand Insti- 
tute“; but probably the most interesting of his publications are two 
memoirs “* On the Means of Fertilization among some New Zealand Orchids ” 
(Trans. N.Z. Inst., xi, 418) and ‘‘ On the Fertilization of New Zealand Plants ” 
(Lbid., xiii, 241). His work on the “ Ferns and Fern-allies of New Zealand,” 
issued in 1882, is an accurate and useful compendium, containing descriptions 
of all the known species. He is also the author of an “ Introductory 
Class-book of Botany,” which has been largely used in New Zealand schools. 
Mr. J. F. Armstrong, for many years resident in Christchurch, has 
collected largely in the Province of Canterbury, and has published several 
papers of value. Among them are his ‘“‘ Sketch of the Flora of the Province 
of Canterbury” (Trans. N.Z. Inst., xii, 325) and “ Synopsis of the New 
Zealand Species of Veronica’ (Ibid., xiii, 344), the latter publication 
containing descriptions of several new species. He also founded the genus 
Corallospartiwm for the reception of the remarkable plant first described 
by Sir J. D. Hooker under the name of Carmichaelia crassicaulis. 
The Right Rev. W. L. Williams, Bishop of Waiapu, has for thirty years 
given special attention to the botany of the East Cape and Hawke’s Bay 
districts, carefully noting the chief features of the vegetation, and collecting 
copiously. Among his discoveries may be mentioned the remarkable 
Carmachaelia Williamsn, one of the most local plants in the colony. Mr. 
Kirk's paper on the “ Botany of the East Cape District’ (Trans. N.Z. Inst., 
xxix, 509) is largely founded on Bishop Williams’s specimens and notes. 
The collection of Maori plant-names is also a subject to which he has 
devoted much time and labour, and the list appended to this work is in great 
measure due to his friendly co-operation.
