234 FLOBA OF NEW ZEALAND. {Algce. 



Hab. East Coast, Colenso. (Native of New Holland.) 



2. Laurencia virgata, J. Ag., Sp. Alg. v. 2. p. 752. 



Hab. Cape Kidnapper and Parimahu, Colenso. Houraki Gulf and Banks' Peninsula, Lyall. (Native 

 of South Africa and California.) 



Mr. Colenso's specimens closely resemble those from the Cape of Good Hope, on which Agardh founds his 

 species. Dr. Lyall's, from Houraki Gulf, are also decidedly the same ; but those from Banks' Peninsula vary in 

 some degree from the type.

Hab. New Zealand, Forsler. (New Holland.) 



A common species in Australia and Tasmania, but which we have not received from New Zealand.

Hab. East Coast, Colenso. 



5. Laurencia distichophylla ? J. Ag. ; fronde rosea vel purpurascente compressa distiche decomposito- 

 pinnata, pinnis in rachide stricta sursum dilatatis plano-compressis bi-tripinnulatis saepius oppositis distichis 

 patentibus, pinnulis cylindraceis obtusis simplicibus pinnellatisve, ceramidiis ad ramulos pinnularum coinpo- 

 sitarum sessilibus ovato-urceolatis acuminatis, tetrasporis infra apices pinnellarum fasciatis. — /. Ag. Sp. Alg. 

 v. 2. p. 762? 



Hab. Waitemata Harbour, Lyall. Hawke's Bay and Parimahu, Colenso. Bay of Islands, J. B. H, 

 Bavies. 



Fronds 2-3 inches high, densely tufted, decompound, pinnate, sometimes barely bipinnate, sometimes four to 

 five times compounded. Outline ovate. In some of the very compound fronds the ultimate ramuli are now and 

 then not perfectly distichous, but this is rare. Colour a rosy purple, brighter, and almost crimson in some of our 

 specimens. 



We have not seen specimens of Agardh's plant, but judge from his description that it cannot be greatly different 

 from ours. 



6. Laurencia botrycliioides, Harv.; fronde nana purpurascente vel fuscescente compresso-plana disticha 

 decomposite pinnatifida, pinnis pinnulisque in rachide stricta sursum dilatato subexcurrente ssepissime op- 

 positis patentibus, inferioribus majoribus, pinnulis brevissimis cuneatis vel clavatis apice crenatis demum 

 multifido-congestis, pinnellis clavceforrnibus tetrasporas infra apices foventibus, ceramidiis . . . ? — L. botry- 

 oides, Harv. Ner. Austr. p. 82 (partim, nee Ag.). 



Hab. Bay of Islands, J. B. H. Parimahu, Colenso. 



Fronds tufted, rising from matted surculi, erect, 1-3 inches high, the larger specimens three to four times pin- 

 natifid. Eachides flat, especially above, i-l line broad, straight, closely pinnatifid ; the lacinise opposite and patent. 

 Ultimate pinnules very short, at first crenate or tuberculate at the end, afterwards multifid, their divisions all turbi- 

 nate. Colour dull brownish-purple. 



Nearly allied to L. concinna of 'Nereis Australis' (L. eomplmata, Suhr.), but scarcely the same. It also 

 resembles L. pinnatifida, var. Osmunda, and our L. dutiokopkglla, but is distinguished by the colour and shape of the 

 ramuli.

 Sandwich Islands, etc.)
