 Antarctic regions.

Podetia in Mr. Colenso's specimen, of a stiff, strong growth, swelling; axils widely gaping, the fissures some- 

 tunes extending along the podetia for some distance. Occurs in Tasmania and the South Polar regions, as well as 

 over the northern hemisphere generally.

 Hab. Northern Island, Colenso. 



The specimen is barren, and shows no trace of perforation at the axils ; but the habit so completely accords with 

 the common European species, that there can be little doubt that it belongs to it. Mr. Colenso has found a plant 

 which may probably be a state of this Lichen, or of the foregoing, but, being barren, this pomt can hardly be satis- 

 factorily ascertained in so difficult a genus. The podetia are buried two inches deep or more among ^anumsco 

 P arJ? etc., and rise as much above it; they are twice or thrice forked, having the apices decurved and lotted 

 with scales tolerably densely from the base to the summit; the bark becomes partly naked through the desqua- 

 mescence of the epidermis, and is rather cartilaginous than membranaceous, though very flexible when moist ; axils 

 imperforate ; colour glaucous green ; scales pure white below. 0. squamosa occurs in Tasmania and the Antarctic 

 regions, as well as in all Europe and North America.

This plant bears a considerable resemblance to C. amaurocrcea, Sehaer.! Exs. n. 70, but is manifestly different, 

 because it does not bear closed eups, but has only perforated axils. Neither can it be a form of C. uncialu because 

 h species has not a squamuloso thallus. In faet, its real ally is C.farcala, from which it is readily, but perhaps 

 Especially, distinguished by a very different habit and colour. The podetia are from 1-3 inches highly 

 crowded straight, or nearly so, the occasional main branches being also straight; the lips are brown and ste fated 

 True cups none, but the perforated axils (especially in the younger plant) form spurious cups, being fringed with 

 hart brown-tipped branches. The base of the old podetia becomes blackish in decay, and is tuberculated with 

 whitish spots/which are portions of the ruptured epidermis. (Cf. 0. rangiferina) Whether this plant may P os-
