Art. XXXIV. — On Recent Changes in the Noinenclature of the Neio 

 Zealand Ferns. By John D. Enys. 



[Read before the Philosophical Institute of Canterburij, October 5, 1870.] 



In the Synojjsis Filicum of the late Sir W. J. Hooker and J. G. Bater 

 (London : 1868), a considerable number of changes have been made in the 

 names of the Ferns of New Zealand, given in Dr. J, D. Hooker's Handbook 

 of the New Zealand Flora, 1864, and as these newly adopted names will be in 

 future accepted and employed by botanists, I have drawn up the following 

 list for the assistance of our local collectors. 



It will be observed that the list also includes some new species, which have 

 been added to the Flora of the country since the publication of the first 

 volume of the Handbook, although some of them are mentioned in the 

 "Additions, Corrections, etc.," p. 722, of the second volume. 



These new species are, — 

 Gleichenia dichotoma, — from the Hot-springs of Karapiti and Rotomahana. 

 Hymenophyllum ciliatum, — discovered by W. T. L. Travers, on the Nelson 



mountains. 

 Loviaria dura, — Chatham Islands. 

 Nephrodium unitum, — Hot-springs, North Island. 



As regards Hymenophyllxmi ceruginosum, Dr. Hooker does not agree with 

 his ftither's opinion, and retains the name ceruginoswn, as he says that the 

 plant from Tristan d'Acunha is not distinct from that found in New Zealand. 



In the /Synojjsis, a new Trichomanes is described, and called Armstrongii, 

 after the discoverer, a son of the Government Gardener of Canterbury. 



[The list given by the author of this paper was imperfect, and has there- 

 fore been included in a complete corrected list of all New Zealand Ferns, 

 which has been printed separately for the convenience of collectors, and 

 issued with Part 2 of the Proceedings, 1870. — Ed.] 



Art. XXXV. — On some Algse from the Chatham Islands. By Professor 

 J. Agardh, of Lund. Communicated by F. von Mueller, C.M.G., 

 M.D., Ph.D., F.R.S. 



[Read before the Well'nujton Philosophical Society, October 22, 1870.] 



In submitting this brief notice of the Algce, collected by Mr. Travers in the 

 Chatham Islands, I have a double object in view. I wished to place on i-ecord 

 the results of the examination of these species, as emanating from a philoso- 

 pher, who, as the worthy descendant of a great investigator in phytology
