A. New Zealiind Alg*. 



Verv little attention has until quite lately been bestowed upon the Fresh-Water 

 Alg* of New Zealand 1 ). In Sir J. D. Hooker's Flora Nova? Zelandhv II (in the Botany 

 of the Antarctic voyage of Erebus and Terror. II. London 1855) there are descriptions 

 of the following species: Bostrychia distans Harv., Vaucheria Diliwynii Ag., Viva crispa 

 Lightf. (Prasiola er. et antarctica Kutz.),? Viva bullosa Roth, Batrachospermum monili- 

 forme Roth, Tyndaridea anomala Ralfs, ? T. byssoidea Harv., (Oscillatoria sp.), Nostoe 

 verrucosum Vauci-i., Tolypothrix irregularis Berk. In Hooker's Handbook of the New 

 Zealand Flora (1867) no more species are enumerated. Mr A. Grunow (in Reise S. M. 

 Fregatte Novara um die Erde, Bot. Th. 1. Wien 1867) has added to the list: Oscillaria 

 Cortiana (Poll.) Kutz., Hyplteotrix Braunii Kg. f., Anabwna bullosa Kg., Calotlirix 

 stuposa Kg., Dictyonema membranaceum Ag., Cladophora Hochstetteri Grun., CL flavida 

 Kg., Chroolepus odoratum (Ltngb.) Kg., — />' pulvinatum Grun., Stigeoclonium uniforme 

 (Ag.) Kg., Bulboelioete minor A. Br., Cosmarium Broomei Thwait., C. turgidum Bréb., 

 Staurastvum muricatum Bréb. (and besides several Diatoms). In his paper »On the Flora 

 of the Isthmus of Auckland and the Takapnna District» in Transact. a. Proc. N. Z. Inst, 

 1871 vol. IV. Wellington 1872) Mr T. Kirk enumerated a few species, but only one new 

 one for the islands: Chroolepus aureum Harv. Pahnella cruenta Ag. we meet with in a 

 paper »On new and rare Cryptogames from Otago» by W. Lauder Lindsay (Transact. 

 Bot. Soc. of Edinb. VIII (1863) p. 283). A note »On the Occurrence of Hcematococcus 

 sanguineus on the Wool of a dead sheep» by Swen Berggren was published in Transact. 

 N. Z. Inst, VII (1874) p. 369—370, Pl. 24)'. 



Mr. W. M. Maskell has published 2 papers on the Desmids (Contributions towarcls 

 a List of the New Zealand Desmidiea' in Träns. Proc. N. Z. Instit, vol. XIII (1881) pag. 

 297—317, Pl. 11—12; On the New Zealand Desmidiea? 1. c. vol. XV (1883), p. 237— 

 259, PL 24 — 25), in the last he inserts a nominal list, including some species already 

 published by Dr Spencer (1. c. vol. 14), which list I reprint here. My own remarks I 

 will inclose in ( ) and some of W. Archer's (in Grevillea vol. 10 (1881) pag. 28) in
