New or noteworthy Hepaticae from Florida 



Alexander W. Evans 

 (With plate 5) 



The following notes are based almost entirely on three collec- 

 tions of Hepaticae from southern Florida, recently made under the 

 direction of the New York Botanical Garden. The majority of 

 the specimens were gathered in the region south of Miami. Dr. 

 Small has already called attention to the physiographic pecuh'ari- 

 ties of this district and has commented upon the intimate relation- 

 ship which exists between the higher plants found there and those 

 native to the West Indies. "*" The Hepaticae bring out the same 

 relationship ; more than half the species in the collection have also 

 been found in the West Indies or in other parts of tropical Amer- 

 ica, and the others find their closest alHes among species from 

 these remons. 



The collections embrace only twenty-one species In a con- 

 dition to be identified ; three of these, however, are apparently 

 undescribed, and six of the others are here definitely recorded for 

 the first time from the United States. Nine species, therefore, are 

 new to our hepatic flora. The remaining species, all of which have 

 previously been collected in Florida, include one Ricca^dia {R. 

 pinguis), one Plagiochila {P. hidoinciana^, one Radida {R. australis)^ 

 s^v^w Lejetineae {Microlejeiinea htcens, Lejennea americana, Cheilo- 

 lejemiea phyllobola^ Etiosmolejetinea dtiriuscida^ E, opaca, Brachio- 

 lejetmea corticalis, and Mastigolejeimea anricidata) and tw^o species 

 of F7f2dla7iia {F, Kun::ei and F. caroUnianci). The additions to
