Greenland's Lichen- Flora.— By J. S. D. Braiith and Chr. 

 Groenlund, Copenhagen, 1888. 



The first of these works contains an account o^ the Lichens 

 of the region mentioned from the collections of C. Spegazzini in 

 1882, of Cunningham in 1868, and other collectors. But the 

 author does not seem to have known of the collection of the 

 Hassler Expedition of 1872, the lichens of which were collected 

 by Rev. Thomas Hill, and a few of them (new species) were 

 described by Tuckerman in Abs. Lich., No. 4, 1877. The nam- 

 ber of species in Nylander's list is nearly 100, several of which 

 are new. Other additions would probably be made by a compe- 

 tent student of the Hassler collection. 



The second work is the fullest list of Greenland Lichens yet 

 n^ade. It is preceded by an interesting account of the Greenland 

 Lichen literature and collectors. The number of species is about 

 150- The work is in Danish, except a few notes in Latin.

 n- sp. Anemone heterophylla, Nutt., is reduced to a van'cty of 

 A. dichotoma, L., and several changes are made according to the 

 principle of using the oldest specific or varietal names.
