190 CRYPTOGAMIA ANTARCTICA. [Puegia, 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. 
PraTE CXCIII. Fig. 1.—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. ; filis 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 patentissimis obtusis approximatis remotisve, articulis diametro brevi- 
oribus quadratis v. + longioribus. Nobis in Lond. Journ. Bot. vol. iv. p. 294. (Tas. CXCII. Fig. IIT.) 
Haz. Hermite Island, Cape Horn; in the sea. 
Cespites intertexti, horizontaliter extensi, atro-olivacei, rigidi. Fila intricata, irregulariter parce ramosa, latius- 
cula, C. simpliciuscule diametro duplo excedentia. Rami flexuosi, ssepe nudi, non raro ramulis involutis pectinatis 
obsiti, ut in C. flexuosa. Color luride ater v. virescens, opacus. Substantia siccitate rigida :—chartee minime adheret. 
Prarn OXCH. Fig. IIL.—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.; filis intricatis incomptis atro-viridibus opacis 
flexuosis rigidiusculis capillaribus irregulariter subramosis, ramis valde remotis elongatis simplicibus, ramulis 
perpaucis patentissimis filiformibus sepe secundis articulis diametro «equalibus v. 4-2 plo longioribus, sac- 
culum endochromatis intus foventibus. Nobis in Lond. Journ. Bot. vol. iv. p. 295. (Tas. CXCII. Fig. IV.) 
Has. Hermite Island, Cape Horn, and the Falkland Islands; on sea-weeds, stones, and shells. 
Cespites intertexti, opaci, luride virides, subhorizontaliter extensi. Fila 1-2 unc. longa, remote et irregulariter 
ramosa; rami ramulis perpaucis aucti :—charte non adheret. 
Allied to C. riparia, but more robust, also near the C. flagelliformis of the Cape of Good Hope, but with a 
very different habit from that plant. 
Puare CXCH. 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. 
Has. 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.
