FROM THE FALKLAND ISLANDS. 213 
NEUROPOGON MELAXANTHUM, Nyl. Syn. p. 272. , 
E. Falklands, Gaudichaud, d'Urville, Hooker, Cunningham, Linney, 
Skottsberg. W. Falklands, several localities, Firmin, Vallentin. 
Distris. Arctic, antarctic, and alpine regions. 
Some exceedingly fine specimens from an exposed headland on Saunders 
Island were brought home by Mrs. Vallentin. Hooker, who devotes con- 
siderable space to N. melaxanthum, remarks :—“ It is in the Falkland 
Islands that this species most abounds, covering the surface of the quartz 
rocks with a miniature forest, seeking the most exposed situations, and there 
attaining its greatest size and beauty. In these islands, too, all the five 
varieties I have enumerated may be found growing within a few feet of 
each other, and so associated as to leave little doubt that they are states 
depending on age rather than marked races " (Fl. Ant. ii. р. 520). 
N. TRACHYCARPUM, Stirt. Gen. Usnea, p. 7. 
E. Falklands ; Port Stanley, Skottsherg. 
DrsrRIB. Southern parts of 5. America. 
ALECTORIA OCHROLEUCA, Nyl. Prodr. p. 47. 
E. Falklands, Hooker. 
DISTRIB. Alpine regions, cosmopolitan. 
A single specimen of A. ochroleuca was found under Usnea barbata in 
Hooker's herbarium. 
RAMALINA LINEARIS, Ach. Lich. Univ. p. 598. 
E. Falklands ; Port Stanley, Shottsberg. 
DisrRIb. Probably cosmopolitan. 
Most of the old records of R. linearis and KR. scopulorum refer to 
Г. terebrata. Darbishire, however, who lists А. terebrata from Fuegia, 
records №. linearis also as gathered by Skottsberg at Port Stanley. 
В. scoputorum, Дел, Lich. Univ. p. 640 ; Hook. f. Fl. Ant. її. p. 522,

E. Falklands, Hooker; Port Louis, Skottsberg. W. Falklands, Vallentin. 
DisrriB. Probably cosmopolitan. 
One has only to refer to Miss Knowles’s interesting account of the 
Ramalina vegetation and its ecology (713, рр. 87-101) to appreciate the 
difficulty of naming foreign material. In spite of careful study, Miss 
Knowles finds it exceedingly difficult to place many of the British maritime 
forms according to the present classification, and she is inclined to take 
а wide view as to the limits of А. scopulorum. 
R. terebrata, the common form in the Falklands, is allied to this species, 
but it is well marked and sufficiently distinct, until further information is
