widely recognized as valid, Austin, in fact, made the reduction many 
years ago but considered the American species a variety of the African F. 
brunnea Spreng. 1 2 When I revised the Frullaniae of North America, north 
of Mexico, I was able to show that F caroliniana was different from F. 
brunnea , 3 but as I then had no authentic specimens of L. obcordata ior com- 
parison I attempted to maintain our southern plant as distinct and described 
and figured it under Sullivant’s name. It is now evident that the type speci- 
mens confirm Austin’s conclusions at least in part. Another species which I 
would also reduce to F obcordata is F Martiana Gottsche, based on Brazil- 
ian specimens collected by von Martius. The material at Vienna shows 
more of the lobules explanate than is normal in F obcordata, but this pecu- 
liarity, which is dependent upon external conditions, is not supported by any 
other differences of importance. The specimens also agree in being 
autoicous. The synonymy of F obcordata follows : 
Frullania obcordata Lehm. & Lindenb, in G. L. & N. Syn. Hep. 447. 1845, 
Jungermannia obcordata Lehm. & Lindenb. in Lehmann, Pug. Plant.

On trees. Type locality; Guiana (collector unknown). Florida to 
Louisiana. Also widely distributed in tropical America.
