Order Gigartinaceæ.

I have a large number of species belonging to this order, but so far have been able to identify a few of them only. It presents unusual difficulties.

150. Rhodoglossum latissimum, J. Ag., Epicr., p. 187. (Also Bldr. Alg. Syst., iii., p. 27; (?)Halymenia latissima, Harv., Fl. Ant.)

New Zealand: Berggren. Lyall Bay: Reinbold (amongst specimens sent Home by myself).

151. Gigartina divaricata, Hook., Crypt. Fl. Ant., p. 75. (J. Ag., Epicr., p. 195; Anal. Algol., cont. v., p. 10.) G. pistillata: Fl. Nov.-Zel. (partim).

Bay of Islands: Berggren. Kekerangu: R. M. L.

Var. gymnongongriodes, J. Ag., loc. cit.

Bay of Islands: Berggren.

152. Gigartina livida, Turn., Hist. Fuc., vol. iv., pl. 254. (J. Ag., Anal. Algol., cont. v., p. 11.) G. pinnata, J. Ag., Sp. Alg., p. 270; Epicr., p. 196: Harv., Phyc. Austr., pl. 68.

Wyckliffe Bay: R. M. L.

153. Gigartina flabellata, J. Ag., Epicr., p. 194.

New Zealand: Harvey Gibson (Journ. of Bot., June, 1893). Lyall Bay: R. M. L.

154. Gigartina clavifera, J. Ag., Epicr., p. 194.

Bluff: Berggren. Akatore, Brighton, Lyall Bay: R. M. L.

155. Gigartina laciniata, J. Ag., Epicr., p. 197.

Chatham Islands: (Agardh).

156. Gigartina protea, J. Ag., Bidr. Alg. Syst., part iv., p. 29.

Western coast of New Zealand: (Agardh). Kekerangu, Lyttelton: R. M. L.

– 334 –

The identification of my Lyttelton specimens is due to Agardh, but is somewhat doubtful.

157. Gigartina polyglotta, J. Ag., Bidr. Alg. Syst., part iv., p. 29.

Western coast of New Zealand: (Agardh).

158. Gigartina alveata. 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: R. M. L. Probably common in the South Island at least: R. 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, pl. 119. (J. Ag., Epicr., p. 190.)

Tauranga, Bay of Islands: Berggren(?). Petone (Wellington Harbour): R. M. L.

161. Gigartina macrocarpa, J. Ag., Epicr., p. 683. (G. pistillata: 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 (Amberley), Lyall Bay: R. M. L.

As most of my specimens are barren, it is possible that an allied species may sometimes have been mistaken for G. decipiens.

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.

– 335 –

166. Gigartina ancistroclada, Montagne. J. Ag., Epicr., p. 198.

Akaroa: D'Urville Otago: Lyall.

167. Gigartina burmanni, J. Ag., Epicr., p. 204.

“Specimen vero (i.e., Gigartina burmanni) me habuisse ex littore occidentali Novæ-Zelandiæ habui mihi a Ferd. de Mueller missum quod quonam modo a capensi specie dignosceretur, mihi quidem hodie non liquet.” (J. Ag., Anal. Algol., cont. v., p. 27.)

168. Gigartina lanceata, J. Ag., Anal. Algol., cont. v., p. 29. West coast of New Zealand: Baron F. von Mueller.

169. Gigartina fissa, Suhr. J. Ag., Epicr., p. 20. (Iridea lanceolata, Harv., Fl. Nov.-Zel., ii., p. 252.)

170. Gigartina circumcincta, J. Ag., Epicr., p. 202. (Gigartina radula, Harv., Fl. Nov.-Zel.)

Apparently a very common species from the Bluff northwards: R. M L.

171. Gigartina atropurpurea. Bidr. Alg. Syst., iv., p. 31. (Iridea atropurpurea, J. Ag., Epicr., p. 181.)

Bay of Islands(?): Berggren. Worser Bay: R. M. L.

172. Gigartina apoda, J. Ag., Anal. Algol., cont. v., p. 31. New Zealand: (Agardh).

173. Gigartina grandifida, J. Ag., Epicr., p. 684.

Chatham Islands: Travers(?).

(Vide Bidr. Alg. Syst., iv., p. 30.)

174. Gigartina rubens, J. Ag., Bidr. Alg. Syst., iv., p. 30. (Anal. Algol., cont. iv., p. 34.)

New Zealand: (Agardh).

175. Gigartina orbitosa, J. Ag., Anal. Algol., cont. v., p. 36.

New Zealand: (Agardh).

I have specimens of one or all of the last three species, but at present am quite unable to distinguish them satisfactorily, so I give no localities.

176. Gigartina longifolia, J. Ag., Anal. Algol., cont. v., p. 39.

New Zealand: (Agardh).

182. Dactylmenia berggreni, J. Ag., Anal. Algol., cont. v., p. 51. (Kallymenia berggrenni, J. Ag., Epicr., p. 221. K. harveyana: Fl. Nov.-Zel., p. 251(?).)

Bluff and Lyall Bay (very sparingly), Bay of Islands (plentifully, on calcareous incrustations): Berggren. Lyall Bay: Reinbold (amongst specimens sent Home by myself).

184. Dactylmenia laingui, J. Ag., Anal. Algol., cont. v., p. 54.

Akatore: R. M. L. St. Clair, Green Island beach: J. C. S.

185. Callophyllis calliblepharoides, J. Ag., Epicr., p. 231. (C. hombroniana, Hook, and Harv., in Fl. Ant., tab. 72, fig. 2.)

Common along the east coast of the South Island from the Bluff to Banks Peninsula: R. M. L. Lyall Bay: Reinbold (amongst specimens sent Home by myself).

186. Callophyllis hombroniana, Mont. J. Ag., Epicr., p. 232. (C. erosa, Hook. and Harv., Fl. Nov.-Zel., p. 250, figs. 1, 3, and 4, but not 2.)

Probably the most abundant species of the genus, but Agardh's description is by no means satisfactory. Apparently common on the east coast of the South Island, but perhaps confused with other species.

187. Callophyllis coccinea. Fl. Nov.-Zel., p. 250.

Tauranga: Davies.

Var. a cornea, J. Ag., Bidr. Alg. Syst., part iv., p. 37. Chatham Islands: Dr. Schauinsland; R. M. L. Akatore, Lyttelton: R. M. L.

– 337 –

188. Callophyllis lambertii, Turn. Hook. and Harv., in Lond. Journ.

New Brighton: Dr. Schauinsland.

It is very difficult to distinguish this species from the preceding, into which it passes.

189. Callophyllis asperata. Fl. Nov.-Zel., p. 250.

Cook Strait: Lyall.

I know nothing of this. It appears in Agardh's list of “Species inquirendæ.”

In both of these cases the identification is not quite certain.

192. Callophyllis centrifuga, J. Ag., Epicr., p. 688.
