BOTRYCHlUn BITERNATUn. 



THROUGH the courtesy of the Botanical Gazette, we are able 

 to present herewith an illustration of the fern which Dr. 

 L. M. Underwood has recently given specific rank as 

 Botrychium biternatum. The plant itself is not a new one, 

 having been known since 1797, but until the present it has been 

 confused with the varieties of B ternatam. The plant is described 



&OTRYCHIUM BITERNATUM (Lam.) Underw.
