334 Transactions. — Botany. 



The identification of my Lyttelton specimens is due to 

 Agardh, but is somewhat doubtful. 



157. Gigartina polygiotta, J. Ag., Bidr. Alg. Syst., part iv., 



p. 29. 

 Western coast of New Zealand : (Agardh). 



158. Gigartina atveata. Fl. Nov.-Zel., p. 547. (J. Ag., 



Anal. Algol., cont. v., p. 20.) 

 New Zealand : Banks ; Cunningham ; Hooker. Bay of 

 Islands : Berggren. 



159. Gigartina angulata, J. Ag., Epicr., p. 197. {Vide also 



Anal. Algol., cont. v., p. 20.) (? G. stiriata, Harv., 

 Fl. Nov.-Zel.) 

 Chatham Islands, Bluff: Berggren. Brighton (Otago), 

 Double Corner (Amberley), Lyall Bay: B. M. L. Probably 

 common in the South Island at least : B. M. L. 



Professor Harvey Gibson also describes G. stiriata as from 

 New Zealand (Journ. of Bot., June, 1893). I have seen one 

 of his specimens, and am satisfied that it is G. angulata, 

 J. Ag. The true G. stiriata is a native of Cape Colony. 



160. Gigartina chapmanni. Fl. Nov.-Zel., p. 291, pi. 119. 



(J. Ag., Epicr., p. 190.) ■ 

 Tauranga, Bay of Islands: Berggren{7). Petone (Wel- 

 lington Harbour) : B. M. L. 



161. Gigartina macrocarpa, J. Ag., Epicr., p. 683. {G. pis- 



tillata : Fl. Nov.-Zel., ii., p. 252, partim.) 



Bay of Islands : Berggren. 



The old species G. pistillata has been split up into several 

 by Agardh. It was said to be common on the New Zealand 

 coast. It will probably be found that the common form is 

 G. divaricata. 



162. Gigartina disticha, J. Ag., Epicr., p. 194. (Anal. 



Algol., cont. v., p. 10.) 

 Dunedin : Berggren. 



163. Gigartina marginifera, J. Ag., Epicr., pp. 196,683. 

 Dunedin, Warrington, Banks Peninsula: Berggren. 



164. Gigartina decipiens. Fl. Nov.-Zel., p. 547. (J. Ag., 



Epicr., p. 195; also Anal. Algol., cont. v., p. 20.) 

 Dunedin, Banks Peninsula : Berggren. Akatore, Lower 

 Green Island, Double Corner (Amberlev), Lvall Bav : 

 B.M.L. 



As most of my specimens are barren, it is possible that an 

 allied species may sometimes have been mistaken for G. deci- 

 piens. 



165. Gigartina insidiosa, J. Ag., Anal. Algol., cont. v., p. 22. 

 This plant is apparently from New Zealand, though no 



definite locality is given for it.
