Professor John W. Harshberger of the University of Penn- 

 sylvania and Professor O. E. Jennings of the University of 

 Pittsburgh have contributed through the verification of rec- 

 ords. Others who kindly aided in revising certain portions of 

 the manuscript group are cited in connection with their par- 

 ticular service. 



"Die Naturliche Pflanzenfamilien" of Engler and Prantl 

 and the "Syllabus der Pflanzenfamilien" of these authors, 

 (1919) form the back ground of the taxonomy and nomen- 

 clature used in the cryptogamic groups exclusive of the Pteri- 

 dophyta, although the specialists revising these have been 

 given full sway, authoritative works being cited. In the Pteri- 

 dophyta and all higher groups the arrangement is essentially 

 that of Britton and Brown's "Illustrated Flora of the North- 

 ern States and Canada," edition of 1913.
