PEESIA. 



Several species of plants have been described by Goppert, Eicbwald, 

 Schenk, and Krasser from various localities in Persia ; the flora is 

 considered by Schenk to point to a Ehaetio age ; ' but the general 

 facias of the vegetation bears a distinct resemblance to the Lower 

 Oolite ^ flora of East Yorkshire. It is not an easy matter to decide 

 between a Ehsetic and Inferior Oolite age when we have but a few 

 fossU plant species as evidence ; the close agreement between many 

 of the elements of these two floras renders their separation a matter 

 of difficulty when the material is not very abundant. Whether or 

 not the Persian plant-beds belong to a Ehaetic horizon, there are at 

 least certain species in close agreement with Lower Oolite types. 



Asplenium Eoesserti; cf. Cladophlehis denticulata (Brongn.). There is an 

 especially close resemblance between some of the large pinnules figured by 

 Schenk and those of similar form from East Yorkshire.

Among the Ehaetic plants described from South America by 

 Szajnocha* (Argentine EepubHc) and by Zeiller" and Solms- 

 Laubach" (ChiU), there are some species comparable with British
