484 FLORA ANTARCTICA. [Fueffia, the 



rands aequilongis curvatis, ramulis alternis subulatis furcatis v. alteme multiftdis, axillis acutis, stictis 

 3-4- v. pluriseriatis. Bostrycliia fastigiata, nolis in Lond. Jonrn. Bot. vol. iv. p. 269. 



Hab. Hermite Island, Cape Horn ; on stones near high-water mark. 



Pusitta, dense fastigiata. Frondes \ unc. longas, e basi in ramos plurinios primarios divisae, rubro-purpureae. 

 Caidis brevissimus. Rami elongati, curvati, apicibus arete ineurvis, ramulis simplicibus multiiidisve ornati : — chartae 

 laxe adhaeret. 



Possibly only a variety of the preceding ; from which, however, it differs conspicuously in the very abbreviated 

 stem, the consequently longer, more divided branches and the duller colour. 



3. Stictoslphonia vaga, Hook. fil. et Harv. ; caulibus flexuosis vage dichotome ramosis, ramis paucis 

 nudis simplicibus fihformibus subcapillaribus arcuatis medio incrassatis apicibus ineurvis, ramulis nullis, 

 axillis patentibus, stictis minutis multiseriatis, stichidiis longissime pedunculitis lanceolatis acutis. Bos- 

 trycliia vaga, nobis in Lond. Journ. Bot. vol. iv. p. 270. (Tab. CLXXXVI. Fig. I.) 



Hab. Christmas Harbour, Kerguelen's Land ; on rocks and stones above high-water mark, and in 

 damp places at a considerable distance from the sea; abundant. 



Dense caespitosa, fibs intertextis quasi crinita. Frondes \-\ unc. longae, flexuosae, irregulariter ramosae, capil- 

 lars. Siictcs parvse, 6-8-seriatae. Substantia rigida. Color luride purpureas : — chartae laxe adhaeret. 



A remarkably distinct bttle species, of very simple structure. It is abundant in Kerguelen's Land, sometimes 

 inhabiting places some hundreds of feet above the sea, but probably always within reach of the spray. 



Plate CLXXXVI. Fig. I. — Plant of the natural size ; 2, rami of ditto ; 3, portion of ditto ; 4, incrassated 

 ramulus ; 5, ramulus and stichidium ; 6. tetraspores : — all magnified. 



28. LAUREN IA, Lame. 



1. Laurencia pinnatifida, Lamx. far. y. angustata, Hook. ; FL Antarct. Pt. 1. p. 184. 



Hab. Berkeley Sound, Falkland Islands ; abundant on the beach. 



One of the most widely dispersed of the Alga, inhabiting the shores of Europe from Norway to the Medi- 

 terranean ; the Canary Islands ; west coast of Africa, and Cape of Good Hope ; the Peninsula of India ; Australia 

 and New Zealand ; the Pacific Islands, and both coasts of North and South America. This very extended range 

 has, however, its limits ; the plant is neither found so far north as Iceland in the Arctic Sea, nor in the south is it 

 known to inhabit Cape Horn or Kerguelen's Land. 



29. DELISEA, Mont.

 p. 57. Bonnemaisonia elegans, Endl. Suppl. vol. iii. p. 44. Calocladia pulchra, Grev. Herb. Sphserococcus 

 flaccidus, Su/ir. (Jid. Mont.) 



Hab. Christmas Harbour, Kerguelen's Land ; common. 



Magnificent specmiens of this noble Alga were collected by the Antarctic Expedition, though only in Kerguelen's 

 Laud. The previously assigned habitat for the species is New Holland or Tasmania ; but we have seen no other 

 specimens than Mr. Fraser's original one, labelled as from that quarter of the world. It therefore appears to us 

 probable, that the specimen sent by Mr. Fraser, may have been collected in Mc'Quarrie's Island j whence other 

 Antarctic plants were brought to that gentleman in Sydney, some of which have since found their way into our 

 Herbaria as of Australian origin.
