available to the author (since they are distributed gratuitously to all 

 the great libraries throughout the world) have not been made use of. 

 The limited circulation of American botanical periodicals in Europe 

 appears to indicate also that authors in that part of the world depend 

 too largely on the assiduity displayed by Americans in the distribution 

 of reprints. — Francis E. Lloyd, McGill University. 



Flora of California. — The fifth part of this important work, 1 

 issued early in February, comprises 62 pages, completing Portulac- 

 aceae from Calandrinia, containing Caryophyllaceae, Ceratophyllaceae 

 and Nymphaceae complete, and carrying Ranunculaceac through 

 Anemone. It is illustrated with 13 text figures, those delineating the 

 flowers of 11 species of Silene being particularly helpful. A new 

 genus, Eremolithia, is proposed, based on a remarkable plant found in 

 Owens Valley; Achyronychia rixfordii Brandegee, is the only new 

 species. The steady progress of this great Flora is most gratifying, 

 especially to western botanists. — S. B. Parish.
