 Auckland Islands.) 



5. Callithamnion scopariim, Hook. fil. et Harv., Fl. Ant. v. 2. p. 490. t. 189./. 3. J. Ag. Sp. Alg. 

 v. 2. p. 35. Phlebothamnion scoparium, Kiitz. Sp. Alg. p. 656. 



Hab. Preservation Harbour, West Coast, and Foveaux Straits, Lyall. East Coast, Colenso. (Native 

 of Falkland Islands, and Cape Horn.) 



6. Callithamnion Colensoi, Harv. ; fronde robusta dendroidea atropurpurea, caule ultrasetaceo corticato 

 quaquaversum lateraliter ramoso, ramis sursum longe corticatis apice articulatis ramulis brevibus dichoto- 

 mo-multifidis imbricatis squarrosis densissime obsessis, ramellis divaricatis subulatis acutis alternis, articulis 

 ramulorum diametro sesquilongioribus. 



Hab. East Coast, and Hawke's Bay, Colenso. 



Our specimens are not in good order, but are sufficient to establish tins as a species quite different from any 

 other New Zealand one. It is allied, however, to 0. purpurifermn of the Cape of Good Hope, C. Montagnei of Cape 

 Horn, C. Pikeanum of California, and C. Arbuscula of the North of Europe ; but appears distinct from all these. 

 Frond dendroid, 2-3 inches high, the main stem as thick as sparrow's-quill below, attenuated upwards. All 

 the branches are densely clothed on every side with minute, squarrose, very compound ramuli. Colour blackish 

 when dry. 



7. Callithamnion irachygonum, Harv. ; fronde capillari (basi vix setacea) alterne divisa quaquaversum 

 ramosa e basi fere ecorticata, ramis elongatis virgatis subsimplicibus iterum alterne ramosis dense plumula- 

 tis, plumulis elongatis linearibus angustis pinnatis vel bipinnatis, ramulis brevibus sensim attenuatis sub- 

 acutis erecto-patentibus, articulis ramorum diametro 2-3-plo, pinnarum subduplo longioribus, pinnularum 

 diametro sequalibus v. sesquilongioribus, tetrasporis globosis secus ramulos seriatis. 



Hab. Blind Bay, Lyall. Tauranga, Davies. 



One or two inches high, densely tufted, flaccid, bright carmine-red. Stem subsimple, set on all sides with 

 lateral, similar branches, which bear a second or third series of similar, rod-like branchlets, the last series of which 

 are clothed with subdistichous plumules. Plumules very narrow, erecto-patent, the lowermost simply pinnate, the 

 upper gradually longer and more compound, those near the middle of the branches very long and bipinnate. All 

 the articulations are short; those of the stem and branches veinless, with a narrow endochrome and thick walls. 

 Tetraspores line the inner faces of the ramuli.— A distinct and pretty little species. 



8. Callithamnion puniceum, Harv. ; fronde subcapillari flaccida decomposite ramosissima basi tantum 

 corticata, ramis multoties pinnatim compositis alternis, plumulis oblongis patentibus basi pinnatis apice bi- 

 pinnatis corymboso-fastigiatisque, pinnulis subulatis acutis (e basi latiore sensim attenuatis), articulis pri- 

 mariis diametro 8-10-plo longioribus pellucidis vel venulosis, secundariis brevioribus, ramulorum diametro 

 2-3-plo longioribus, tetrasporis solitariis ad ramulos lateralibus. 



Hab. Tauranga, Davies. 



Densely tufted, 2-3 inches long, excessively branched, inextricable. Stem and branches decompound, pinnate, 

 the upper divisions at least distichous. Plumules short, patent, either simply pinnate, or the lower half pinnate and 

 the upper bipinnate. Ramuli remarkably tapering from a broad base to an acute point, patent. Substance very 

 tender. Colour a fine purple-lake. — We are unable to give a more satisfactory character of this plant, which never- 

 theless seems not exactly similar to any with which we are acquainted. Our specimens are somewhat decayed. 



9. Callithamnion consanguineum, Harv.; fronde subcapillari decomposite ramosissima, ramis primariis 

 quaquaversum egredientibus sursum longe corticatis, secundariis subdistichis alterne pinnatim compositis 

 articulatis basi nudis apice distiche plumulatis, plumulis fastigiatis basi nudis extra medium pinnatis, pinnis
