A NEW SPECIES OF METZGERIA FROM THE 

 GALAPAGOS ISLANDS* 



By Alexander W. Evans 



The collection of Hepaticae made in the Galapagos Islands 

 by Dr. Alban Stewart, while acting as botanist to the Expedition 

 of the California Academy of Sciences, includes between fifteen 

 and twenty species. One of the most interesting of these is the 

 Metzgeria described below. It is not only a distinct addition to 

 the genus but it apparently represents the first member of the 

 Metzgeriaceae (Jungermanniales anacrogynae) to be reported 

 from this group of islands.
