HOOKER (William Jackson). Genera Filicum. 410. Lon- 

 don, 1842. Illustrated by 120 colored plates, representing 135 

 genera and sub-genera. 



Species Filicum. 5 vols. 8vo. London, 1846-1864. 



Contains among 304 plates nineteen of North American Ferns. 



HOOKER (W. J.) and BAKER (John Gilbert). Synopsis 

 Filicum. Second Edition, Svo. London, 1874. Contains de- 

 scriptions of all Ferns known at that date, and is valuable for 

 the determination of species from beyond our limits. It lacks 

 one very essential feature of a systematic work, namely, a key 

 to the genera, and the grouping of the species is such as to 

 make it often difficult to identify them. 



HOOKER (W. J.) and GREVILLE (Robert Kane). Icones Fi- 

 licum. 2 vols. folio. London, 1831. Containing 240 plates, of 

 which 13 represent North American Ferns. 



Spermaphyta. 



The only work attempting to describe all our flowering 

 plants is incomplete, covering only the Gamopetalae. It stands 

 as a monument to its author, the leader of American Botany 

 for many years.
