FLOKA OF WESTERN ESKIMAUX-LAND. 47 
LICHENES. 
(Auctore Churchill Babinyton.) 
281. EvERXi.A dlvergens, Fries, Lich. Europ. p. 21. — Cornlculana divergency Ach. Nortoii 
Sound and Kotzebue Sound, gro'sviug in dense patches on the ground, mixed with Vaccinium Viiw- 
idoiUj Grasses, and with other Lichens, as Evernia ochroleuca, Ceirana cucuUafa, C. Ishiuffira, and 
Cladoiiia rangiferina. 
The specimens from "Western Eskimaux-land agree with the authentic ones gathered in Lnpland by 
Wahlenberg, the original discoverer. No apothecia seem to have been obscn'ed. Scharer mentions 
(Euum. Crit. Lich. Europ. p. 5) having rectived specimens from Eschscholtz, collected iu Kotzebue Souiul. 
The range of this species, so far as is known, is limited to the higher latitudes of the Northern hemi^plii're. 
It is found as far south as Newfoundland (lat. 50'^ N.) in the New World, and ascends to the Arctic circh.' 
at G-reat Bear Lake. In Europe it hardly occurs below latitude 60° N., and it rises to the Arctic circle in 
Lajilnnd. 
282. Evernia ochroleuca, Fries, Lich. Europ. p. 22. — Cornicularia ochrokuca, Ach. Kotzebue 
Soiuad; on the ground with other Lichens. Normal form; harrcn. 
A far more diffused plant than -£/. diverjcm, occurring in the north of Europe commonly, aud fomul as 
far south as Spain and Corsica ; it is also a native of the Canary Islands and New Zealand. 
283. Cetraria Islandica, Ach., Meth. Lich. p. 394. Nortou Sound; Kotzebue Sound; fertile. 
284. Cetraria cucuHata, Ach., Meth.'Lich. p. 293. Norton Soimd ; Kotzebue Sound ; fertile. 
In a specimen from Nortou Sound the upper part of the thallus is sparingly frmged with black teeth. 
C cucullata occurs from about latitude 40^^ N. to the Arctic regions, both in the Old and New World, being 
found in the Pyrenees, the Altai mountains, and the White Mountains, penetrating to Lapland, and liaving 
been gathered by Pranklin in his first journey to Arctic America. Fries and Schicrer mcntiou that it is 
ordinarily accompanied hy C. nivalis; as yet, however, the latter plant only has been observed in Britain. 
I liave seen no specimens of either from the Southern hemisphere. 
285. Cetraria ylauca, Ach., var. substraminea, C. Babing. in Hook. Joum. Bot. and Kcw 
Misc. vol. iii. p. 248. — Thallus ample, lacunose, lobes rounded ; colour oclirolcucous, but passing into 
glaucous, here and there suffused with a reddish tint; beneath black, chestnut on the edges. KotzeJnie 
Sound, growing among sticks, Grasses, and PoJyiricha ; barren. 
The colour, which is the same as that of Parmelia capemta, appears to be accidental, for in the less 
exposed parts of the thaUus it ineUnes to glaucous. The discovery of this species m Kotzebue Sound extends 
its known ranffe iu North America about 10° of latitude. For its geograpliical distribution, see Hook, fil, 
Fl. Antarct., and add "Nepal" to the stations there mentioned. 
286. Nephroma polaris, Ach., Lich. Univ. p. 521. Kotzebue Sound, among Mosses and deatl 
leaves; barren. 
Dr. J. L. Hooker (Flora Antarctica, p. 521) has indicated the region which this plant inhabits. Dr. 
Hooker's plant, however, appears to be distinct ; it has, indeed, the ample thallus of JST.polan's, but becomes 
deeply lacunose and foveolated ; it is much more allied to A", cellulosa, Ach., with wliich I am imperfectly 
acquainted ; that species, however, is much smaller and of a different colour.
