is no glossary but all of tin- trims used are explained in tin- in- 

 troduction. Seventy-six species are described, including 3 species 

 of Equisetum, 8 of Lyco podium, 5 of Selaginella and one of 

 Isoetes. Under Botrychium four species are described. Eleven 

 species of Dryopteris, the largest genus in the state, are re- 

 corded, D. hexagonoptern being the only specie of the Phegop- 

 teris group though it is noted that D. polypodiodes has been 

 reported from the state but no species have been located. The 

 three spinulose forms are clearly separated both in the key and 

 the drawings. One fern is described as an escape from cultiva- 

 tion, Pteris multifida, a slender form often grown in fern dishes, 

 "in Florida and as far north as Wilmington it has escaped and is 

 often found growing in the open especially on stone and brick 

 walls. Native of China." Almost no varieties of the species are 

 described. Most of the illustrations are evidently from her- 

 barium specimens and the author has indicated the bent stems 

 necessary to place large fronds on herbarium sheets, and in 

 places the folding over of pinules in pressing. This is noticed 

 most particularly in the illustration of the Narrow-leaved chain- 

 fern. A drawing from a fresh specimen would have been more 

 accurate and pleasing.
