 NOTES ON THE HEPATIC^ OF CALIFORNIA 1 



BY 



ALEXANDER W. EVANS 

 Yale University 



The Hepaticae of California were ably described in 1899 by 

 Howe 2 , who recognized eighty-five species and several distinct 

 varieties. During the twenty-four years that have since 

 elapsed, ten additional species from California have been re- 

 corded in the literature. Of these the following were proposed 

 as new : Aplozia pcndletonii Pearson, Cephalosia patulifolia 

 Steph., Fossombronia hispidissima Steph., and Scapania per- 

 laxa Warnst. The others are all northern species with an ex- 

 tensive geographical distribution. 



Within the past few years Mrs. E. C. Sutliffe, of the Cali- 

 fornia Academy of Sciences, has interested herself in the 

 Hepaticae and has collected diligently in several parts of the 

 state. Her careful collections, supplemented by the collec- 

 tions made by various other students, have added eight more 

 species to the flora of California. These and the additions 

 already recorded in the literature are noted in the present re- 

 port. Attention is likewise called to certain changes in 

 irr- nomenclature that affect the species of California, and a few 

 species are critically discussed. Perhaps the most important 



Contribution from the Osborn Botanical Laboratory.
