496 FLORA ANTARCTICA. \Fuegia, the 



Apparently very distinct from any hitherto described species : its remarkable characters are its wavy habit, 

 and the great length and simplicity of the upper branches, which are furnished with more or fewer, short, patent, 

 secund ramuli. 



Plate CXCIII. Fir/. I. — 1, plant of the natural size ; 2, branch and ramuli ; 3, apex of branch ; 4, portion of 

 ditto : — very highly magnified. 



6. Cladophora incompta, Hook. fil. et Harv. ; fills intricatis incomptis atro-viridibus opacis rigidis 

 setaceis tortuosis vix ramosis, ramis longe nudis v. ramulis brevibus pectinatis circinato-inflexis ornatis, 

 ramulis ultimis secundis v. alternis patentissirnis obtusis approximatis rernotisve, articulis diarnetro brevi- 

 oribus quadratis v. -£ longioribus. Nobis in Lond. Joum. Bot. vol. iv. p. 294. (Tab. CXCII. Fig. III.) 



Hab. Hermite Island, Cape Horn ; in the sea. 



Cmspites intertexti, horizontaliter extensi, atro-olivacei, rigidi. Fila intricata, irregulariter parce ramosa, latius- 

 cula, C. simpliciusculis diametro duplo excedentia. Rami flexuosi, saepe nudi, non raro ramulis involutis pectinatis 

 obsiti, ut in C.flexuosa. Color luride ater v. virescens, opacus. Substantia siccitate rigida: — charts minime adhaeret. 



Plate CXCII. Fig. III. — 1, plant of the natural size ; 2, portion of ditto, highly magnified, with abbreviated 

 ramuli ; 3, another portion of ditto and branch : — still more highly magnified. 



7. Cladophora simpliciuscula, Hook. fil. et Harv.; fills intricatis incomptis atro-viridibus opacis 

 flexuosis rigidiusculis capillaribus irregulariter subramosis, ramis valde remotis elongatis simplicibus, ramulis 

 perpaucis patentissirnis filiformibus ssepe secundis articulis diametro sequalibus v. |-2 plo longioribus, sac- 

 culum endochromatis intus foventibus. Nobis in Lond. Joum. Bot. vol. iv. p. 295. (Tab. CXCII. Fig. IV.) 



Hab. Hermite Island, Cape Horn, and the Falkland Islands ; on sea-weeds, stones, and shells. 



Ccespiles intertexti, opaci, luride virides, subhorizontaliter extensi. Fila 1-2 unc. longa, remote et irregulariter 

 ramosa; rami ramulis perpaucis aucti : — charts; non adhagret. 



Allied to C. riparia, but more robust, also near the C.fiagelliformis of the Cape of Good Hope, but with a 

 very different habit from that plant. 



Plate CXCII. Fig. IV. — 1, plant of the natural size ; 2, portion of thread and branch ; 3, cells of ditto : — 

 very highly magnified. 



8. Cladophora glaucescens, Griff. ? Harv. Manual, p. 139. 



Hab. Hermite Island, Cape Horn ; rare. 



We are not at all satisfied with the reference of the Antarctic plant to the British C. glaucescens, which has 

 slenderer filaments. The specimens resemble that species more nearly than any other, and are not in a sufficiently 

 good state for a proper comparison. 



48. OSCLLLATORIA, Fauch. 



1. OsciLLATORiA_p«p«m/, Hook. fil. et Harv.; strato gelatinoso tenaci siccitate translucente purpureo, 

 fills violaceis omnium tenuissimis dense intertextis curvatis longe radiantibus, striis inconspicuis. Nobis in 

 Lond. Joum. Bot. vol. iv. p. 297. 



Hab. Kerguelen's Land; in alpine rivulets, alt. 300-700 feet.
