- 182 CRYPTOGAMIA ANTARCTICA. [ Fuegia, the 
the former of these it differs in being larger, more rigid, and having ramuli of much greater diameter, so that under 
the microscope it is impossible to confound them. Its Cape of Good Hope representative, and indeed, very near 
ally, is the P. setigera, Harv. (Nereis Australis.) 
Puare CLXXXVII.—Fig. 1, branch and ramuli ; fig. 2, portion of a ramulus; fig. 3, another ramulus ; fig. 4, 
favella; fig. 5, spores from ditto ; ‚fig. 6, tetraspores :—all magnified. 
36. CERAMIUM, 4dans. 
1. CERAMIUM rubrum, Ag. Fl. Antaret. Pt. 1. p. 191. 
Haz. Hermite Island, Cape Horn; Falkland Islands, and Christmas Harbour, Kerguelen's Land ; 
very abundant. 
These two Ceramia (rubrum and diaphanum) are very widely distributed throughout the temperate regions 
of both hemispheres : they are also found on the shores of Peru and Brazil. 
2. CERAMIUM diaphanum, Ag. Fl. Antarct. Pt. 1. p. 191. 
Has. Hermite Island, Cape Horn; Falkland Islands; and Christmas Harbour, Kerguelen's Land ; 
abundant. 
37. GRIFFITHSIA, Aj. 
1. GRIFFITHSIA Antarctica, Hook. fil. et Harv. ; filis ceespitosis dichotome ramosis flaccidis, axillis 
inferioribus patentibus, superioribus acutis, ramis elongatis ramulisque nudis ad nodos constrictis, articulis 
cylindraceis superne paulo incrassatis, ramorum diametro sextuplo, ramulorum subtriplo longioribus ;—fructi- 
ficatio deest. 
Has. Hermite Island, Cape Horn, and the Falkland Islands; on ently 
Fila sub 3 unc. longa, fastigiata, parce ramosa, ramis elongatis, distanter ramulosis, ramulis brevibus. Color 
roseus :—charte arcte adheeret. 
Allied to the G. secundiflora, J. Ag., but smaller in all its parts. 
9. GRIFFITESIA corallina, Ag. Conf. corallina, Engl. Bot. t. 1815. 
Haz. Hermite Island, Cape Horn; dredged up in about seven fathom water. 
A solitary barren specimen, resembling the British G. corallina, which is also a native of the Mediterranean 
Sea, Canary Islands, and Cape of Good Hope. 
3. GRIFFITHSIA equisetifolia, Ag. Conf. equisetifolia, Engl. Bot. t. 1479. 
Haz. Falkland Islands; (Agardh.) 
38. BALLIA, Harv. 
1. Barura Brunonis, Harv. Fl: Antarct. Pt. 1. p. 190. 
Var. 8. Hombromana, Fl. Antarct. 1. c. 
Haz. Hermite Island, Cape Horn; Falkland Islands; Christmas Harour, Kerguelen’s Land, and 
the Crozet Islands ; most abundant; always (?) parasitical. 
One of the handsomest, and certainly the most common and widely distributed of the Antarctic Floridee : its 
northern limit in the New World is Patagonia, and the Bay of Islands in New Zealand in the Old. With regard to 
the adoption of the trivial appellation of “ Callitricha," which Agardh proposed for this species (under Sphacelaria), 
it was waived in compliance with the wish of the first discover of the plant, whose name it now bears.
