BAIERA. 



Dicropteris longifolia ; Pomcl's plant was subsequently spoken of 

 by Heer and other authors as Baiera longifolia. 



To avoid confusion between Phillips' English plant and Pomel's 

 species, Nathorst proposed to name the former Baiera Phillipsi, 

 a name which may well be adopted. It is true that Phillips used 

 the specific name longifolia several years before Pomel applied the 

 same term to a distinct plant, but the long-established use of Baiera 

 longifolia in Pomel's sense renders it advisable to adopt the new 

 name Phillipsi for the English species. 



Baiera Phillipsi agrees closely with some forms of Ginkgo sibirica 

 and G. lepida as described by Heer from northern latitudes.

A comparison may be made also with Ginkgo sibirica l as figured 

 by Geyler from Japan. 



The Pihsetic leaves figured by Schcnk 2 as Baiera tceniata bear 

 a close resemblance to B. Phillipsi.

 others of the same type on a large slab of rock. This specimen is 

 precisely similar to the type-specimen of Sphenopteris longifolia,
