60. Echlonia flahelliformis. Fl. Nov.-Zel., p. 218. 

 Wangari Bay : D' Urville. Bay of Islands : Hooker. 



The species of this genus (Ecklonia) are still insuflSciently 

 defined. Juvenile forms vary so much from older forms that 

 until series at all stages of development have been collected 

 we are not likely to be able to classify them properly. 



61. Lessonia variegata, J. Ag., De Alg. N.Z. Mar., p. 6; 

 E.M.L., Trans. N.Z. Inst., vol. xxvi., p. 304. 



Akatore, the Nuggets, Lyall's Bay, Kaikoura (in I'ock-pools) : 

 B. M. L. One specimen, in drift-weed. Tumble-down Bay, 

 Banks Peninsula: B. M. L. Whangaruru ; H. B. Kirk! 



This plant is only found in deep rock-pools at more or less 

 isolated spots on the coast-line. It does not occur in the 

 neighbourhood of Lyttelton or Dunedin. It is very plentiful 

 in the neighbourhood of Wellington, where, however, the 

 Makara Stream (Mr. Kirk informs me) is the western, 

 boundary of its habitat. The immense tree-like South 

 American Lessonias have not yet been authentically recorded 

 from New Zealand. 



62. Macrocystis dubenii (M. pyrifera). Fl. Nov.-Zel., p. 217. 

 This plant is generally reported as everywhere abundant 



on the New Zealand coast, but I was unable to find it on the 

 east coast of the North Island, though I looked for it at the 

 following ports: Napier, Gisborne, Auckland, Whangaroa, 

 Bay of Islands, Mongonui. I have not been able to find any 

 specimens of the extraordinary length mentioned by the 

 earlier voyagers. The longest I have actually measured was 

 about 100 ft. in length ; but the stems were then so twisted 

 into cables that it was impossible to say whether they be- 

 longed to one plant or several. 



63. Chorda lomentaria. Fl. Nov.-Zel., p. 218. 

 Everywhere plentiful on tidal flats, and in shallow rock- 

 pools. 



Order Sporochnaceae. 



64. Sporochnus stylosus. Fl. Nov.-Zel., p. 216, 



" Otago Harbour and Foveaux Strait: Lyall." 

 This plant has not been collected recently, and its oc- 

 currence in New Zealand may be considered somewhat 

 doubtful. 



65. Perithalia capillaris, J. Ag., Till Alg. Syst., vi., p. 5. 

 Barrier Island, Thames : Colenso. 



66. Carpomitra cabrerce. Fl. Nov.-Zel., p. 217. 



Lyall's Bay : Lyall. Hawke's Bay : Colenso. Chatham 

 Islands, Kaikoura, Lyttelton : B. M. L.
