NOTES ON NORTH AMERICAN HEPATICAE— X 1 



Alexander W. Evans 



In a recent paper on New England Hepaticae 2 the writer discussed the vari- 

 able Bazzania tricrenata (Wahlenb.) Trevis. and presented reasons for recognizing 

 the closely allied B. denudata (Torr.) Trevis. of eastern North America as a 

 valid species. In the present paper similar claims are made for B. ambigua (Lind- 

 enb.) Trevis. of western North America, and another related species from the 

 mountains of Virginia and North Carolina is proposed as new. In connection 

 with these two species and in order to give a more complete idea of the distribution 

 of B. tricrenata in North America, the known stations outside eastern Canada 

 and New England are enumerated. 



In describing the genera Targionia and Marchantia in the North American 

 Flora the writer reported certain extensions of range, without citing the specimens 

 upon which the records were based. These specimens are listed below. The 

 paper calls attention also to three species that ought to be reduced to synonymy, 

 reports a species of Mylia as new to North America and records the genus Lophozia 

 for the first time from Florida. 



1. Targionia hypophylla L.; Evans, N. Am. Fl. 14: 31. 1923. 

 Collected on a damp bank, in the winter of 1921-22, near the city of San

 1917; N. Am. Fl. 14: 64. 1923. 



Collected on soil along a stream, in 1920, near Furey, Haiti, by E. C. Leonard

 west of Sanford, Florida, by S. Rapp (No. 94). Species and genus new to Florida. 

 According to the published records the nearest known station for the species is
