of the rarer alpine and subalpine plants. Among the species added by him to the flora are Ranunculus Berggreni, Carmichælia compacta and C. Petriei, Coprosma virescens and C. Petriei, Olearia fragrantissima, Celmisia prorepens and C. Petriei, Myosotis Goyeni, Tetrachondra Hamiltoni, Veronica Petriei, Ourisia prorepens, &c. In company with Mr. G. M. Thomson, he also visited Stewart Island, making several discoveries of interest, as Actinotus bellidioides, Liparophyllum Gunnii, Carex longiculmis, and Ehrharta 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 altitudinal 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 accompanied 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 Institute; but probably the most interesting of his publications are two memoirs "On the Means of Fertilisation among some New Zealand Orchids" (Trans. N.Z. Inst., xi., 418) and "On the Fertilisation of New Zealand Plants" (Ibidem, 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" (Ibidem, xiii. 344), the latter publication containing descriptions of several new species. He also founded the genus Corallospartium for the reception of the remarkable plant first described by Sir J. D. Hooker under the name of Carmichælia 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 Carmichælia Williamsii, 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
