Remarks. — Among many other specimens of fossil plants contained in the 

 collection of the late William Henry Johnson, Dudley, I observed two small 

 specimens of this species. 



Unfortunately, they are not very well preserved, and do not add any additional 

 information to the knowledge of the species. The general growth of the species 

 is well shown in Lesquereux's figures, and their more minute structural details 

 have been illustrated by Zeiller. The fructification consists of a number of 

 elongated sporangia, usually six in number, arranged in a stellate manner 

 around a common point of attachment. It is not yet known to which 

 fern this fructification belongs, as the fertile portion shows no traces of the 

 barren pinnules. 



Horizon. — Middle Coal Measures. 



Locality. — Coseley, near Dudley.

Description. — Frond decompound (4-5 pinnate) ; primary pinnae broadly 

 lanceolate, secondary pinnae lanceolate, and composed of about twenty pairs of 

 tertiary pinnae. The tertiary pinnae are more or less lanceolate, but vary in 

 outline according to their position on the frond. Pinnules attached to the 

 rachis by their whole base and united among themselves, the free portion of the 

 limb is ovate-triangular ; medial nerve clearly defined, and giving off 2-4 simple 

 lateral branchlets, all of which extend to the margin of the pinnule. Fruiting
