FOSSIL FLOKA. 79 



PLATE XXXI. 



" Plumose Pecopterite." 



{Pecopteris plumosa, Brongniart, Hist. Veg. Fos. tab. 121. 

 Filicites plumosus, Artis.) 



This elegant fern is characterized by the plumose or wavy character of the stipes or stems of 

 the fronds, which are tripinnate ; the leaflets are lanceolate and sessile, — that is, are closely 

 attached by their base, without a stalk. The fructification is seen disposed near the margins of 

 the leaflets on the left hand upper part of the specimen. 



From the same locality as the last.
