BAIERA. 



Bicropteris hngifolia ; Poniel's plant was subsequently spoken of 



liy Heer and other auttors as Baiera hngifolia. 



To avoid confusion between PhiUips' 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 hngifolia several years before Pomel applied the 

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



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

 I 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. 



Tig. 47. — Baiera FMlUpsi, Nath. [Type-specimen of Phillips (PI. VII. Fig. 17), 

 York Museum.] (Bloclc lent by the University Press, Camhridge.) 



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

 by Geyler from Japan. 



The Rhsetic leaves figured by Schenk'^ as Baiera tmniata bear 

 a close resemblance to B. Phillipsi. 



V. 3301. PI. IX. Eig. 4. A single leaf occurring with several 

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

 precisely similar to the type-specimen of Sphenopteris hngifolia,
