DR. LINDSAY ON THE LICHEN-FLORA OF GREENLAND. 285 



to thirty species, named according to the nomenclature and classi- 

 fication of Dillenius and Hudson. Several names it is impossible 

 now to identify with modern species.

4. Walker and Mitten : Lichens collected by Dr. Walker of the 

 " Fox " Expedition, under Sir Leopold M'Clintock, on the coast at 

 Frederikshaab, Godhaab, Fiskernaes, Uppernavik, and on Disco 

 (Godhavn). Determinations by Mitten. Journal of Linnean 

 Society, Botany, vol. v., p. 87. This list contains some that are 

 not mentioned by Fries. Extra-Greenland localities were — Port 

 Kennedy, 72° N. lat., on the Boothian peninsula, which occupies 

 a central position among the Arctic- American islands ; Pond's Bay 

 and Lancaster Sound, on the west side of Bafiin's Bay ; and Cape 

 Osborne, with whose geographical position I am unacquainted. 



5. Hayes and James : Lichens collected by Dr. Hayes ; deter- 

 minations by Professor Thomas P. James ; Proceedings of the 

 Academy of Natural Sciences of Philadelphia, 1863, p. 96. These 

 collections were made much more to the north than any of the 

 others, viz., in Smith's Sound, between parallels 78° and 82°. It 

 is not, however, always or clearly stated on which shore they 

 were collected,* though it would appear to have been the eastern 

 or Greenland side. 



Professor James remarks, " Not a single fruited specimen was 

 " to be found in the entire collection," a circumstance of interest 

 in connexion with a fact I have pointed out elsewhere f — the 

 frequency of barrenness (in apothecia) of the Lichens of Arctic 

 countries. It would almost appear that this sterility, or its fre- 

 quency, bears a proportion to the northernness of the latitude. 



James enumerates the following, which were not found, or are 

 not recorded, by other collectors or lichenologists : — 



Alectoria sulcata, Lev.\ Stereocaulon condensatum, 



Neuropogon Taylori, Hook.^ Hffm.% 



Parmelia Borreri, Turn\ Cladonia furcata, Uffm., var, 



racemosa, Flk.** 



* Such an omission becomes of more importance where the Strait is much 

 broader. Thus, in the Kew and other Herbaria, I have found specimens 

 labelled " Baj0&n's Bay " or " Davis Straits." Now, Greenland occupies so 

 decidedly an intermediate position between Europe and America in regard to 

 its general flora, that it is always desirable to know on what side of the bay 

 and straits in question given plant-collections have been made. In the 

 Kew Herb., however, I have frequently met with labels of a much vaguer kind, 

 e.g., " North Pole," '* Arctic regions," " Franklin's first journey," or Parry's 

 " first voyage," without specifying any precise locality ! Vide also p. 300.

X Nylander (Syn., p. 281) gives it only as an Indian species. 



§ Nylander (Syn., p. 273) gives it only as an Antarctic species. Probably 

 it has been confounded with its Arctic representative N. melaxanthus. 



II Nylander (Syn., p. 389) gives its northern limit as Central Norway. 



^ Nylander, (Syn., p. 250) gives its northern limit as Central Sweden and 

 New England, U.S. 



** Nylander (Syn., p. 206) records it as a central-European form, and de- 

 scribes the type as becoming rare northwards. Racemosa is a not uncommon
