CARL SKOTTSBERG, MARINE ALG^I 2. RHODOPHYCEiE. 



Agardh it stains the paper violet, and so do my specimens of L. Hookeriana, while 

 Hohenacker's plant (no. 292) does not seem to possess this quality, the difference be- 

 tween them perhaps being due to the mode of preparation. It lies near at hand to assume 

 that one of the Lophurella species collected in the Falklands must be identical with 

 L. Gaimardi, but it should be remembered that the cortex figured by Bory, Voy. Coq. 

 t. 22 hardly suggests Lophurella. 



Distribution: S. Patag. (first record), Fuegia, Falkl., Kerg., Austral., N. Zeal. 



L. patula (Hook. Fil. et Harv. ) de Toni. — Kylin & Skottsb., p. 53. — Fig. 26 c — d. 

 South Patagonia: Skyring Water, washed ashore near Punta Pvocallosa 

 29. 4. 08; Fitzroy Channel, near the entrance to Skyring, drifted (St. 17 B, 19. 4. 08, ?). 

 Falkland Islands: Darwin Harbour, drifted (St. 10, 16. 1. 08, © ).

Kylin did not find any hairs on the material examined by him; I have observed 

 them on my plants, but they are scarce and not persistent (fig. 26 c). The 1902 collec- 

 tion was made during the winter.

L. comosa (Hook. Fil. et Harv.) Falkenb. 1. c. p. 158, t. 19 f. 31. — Fig. 26 e — f. 



West Patagonia: Puerto Bueno, 1 — 3 m, sand with stones and shells (St, 

 27, 3. 6. 08). South Patagonia: Skyring Water, near Mina Magdalena, 5 — 6 m, 

 sand and stones (St. 22, 29. 4. 08); Fitzroy Channel, 13—14 m, gravel (St, 17, 18. 4.08). 

 Falkland Islands: Darwin Harbour (St. 10, 16. 1. 08 © ). 



L. comosa has been collected but a few times before. The specimens from St. 22 

 are well developed and agree perfectly with the figure in Fl. Ant. II t. 185. In habit 

 it approaches L. patula, but is more densely branched. The fibrillose shoots with their 

 more persistent hairs (fig. 26 e) also serve to distinguish it, and the cortex is different. 

 Var. [5 fibrillifera of Hooker and Harvey 1. c. is a normal state of L. comosa. 



Distribution: Patag. (first record), Falkl.
