ELOBA 01? NEW ZEALAND. 



\Algm, 



patentibus, reticulis ramorum diametro subtriplo, ramuloram duplo longioribus, apicibus obtusis, tetrasporis 

 lateralibus subsolitariis triangulipartitis. 



Hab. Port Nicholson, Lyall. 



Densely tufted, 2-3 inches high, thinner than human hair, excessively branched, the larger branches spreading 

 every way, the lesser gradually more distichous upwards, alternately decompound-pinnate. Stem and branches opaque 

 with veins, the lesser branches alone pellucidly articulate, decompound-pinnate, and alternately plumnlate. Plumules 

 short, fan-shaped, naked below, pinnate above, the terminal pinnae very close together. Articulations twice or thrice 

 as long as broad, those of the branches longest. Colour a rosy-purple. Substance rather flaccid, adhering to paper.

Hab. Bluff Harbour, Eoveaux Straits, and at Otago, Lyall. Maketu, Chapman. (Native of Europe 

 and North America.) 



We had at first regarded these specimens as representing a distinct species, which we should have name 0. te- 

 nerrimum, but on re-examination we fear they approach the northern 0. byssoidenm too nearly to be kept separate.

1. Caulerpa Brownii, Endl. ; caule vestito, ramis elongatis dichotomis, ramulis (foliis) cylindraceis basi 

 subconstrictis erecto-patentibus quadrifariam imbricatis mucronulatis obtusisve. (Tab. CXXI. A.) 



Hab. LyalFs Bay and Chalky Bay, Lyall. New Zealand, Colenso. (Native of New Holland.) 

 A larger and more branching plant than the following, with simple rarnuli. Some specimens, however, are 

 almost intermediate in character between the extreme forms of these supposed species.— Plate CXXI. A. Eig. 1, 

 plant, natural size; 2, four verticillate rarnuli; 3, a ramulus; 4, apex of another ramulus, to show that they are 

 sometimes blunt : — all magnified.

Hab. New Zealand, Colenso. (Native of Tasmania.) 



Our figure represents the typical form, such as we have also received from Tasmania, and formerly described in 

 Hooker's London Journal. On some specimens recently examined, we find simple cylindrical rarnuli mixed with the 

 forked ones, a variation which materially weakens the specific character.— Plate CXXI. B. Eig. 1, plant, natural 

 size; 2, four verticillate rarnuli ; 3, a ramulus :— both magnified.
