118 Mr. J. Morris on recent and fossil Cycadece, 



The Filicites scolopendrioides of Lindley (not of Brongniart, from 

 which it is very distinct, Brongniart's figure representing merely the 

 fructification of an entire leaf, Lindley's figure that of true pinnae) 

 has been placed as a synonym of Z. pectinata, although it differs in 

 having the pinnse wider apart and more obtuse at the apex, not im- 

 portant specific characters.

I am informed, from a recent communication of Prof. Phillips, that 

 the fossils figured in his 'Geology of Yorkshire,' under the names of 

 Cycadites lanceolatus (Zamia Manielii, Br.), C. gramineus (Z. elegans, 

 Br.), and C. latifolms (Z. Youngii, Br.), ought to be placed in the 

 Otopteroid division of Ferns, the veins losing themselves in the upper 

 margin. Seven or eight other species are named in Ad. Brong. 

 ' Prodromus,' the characters of which are not given, viz. Z. Feneonis, 

 acuta, patens, Icevis, Goldicei, Buchanani, pennceformis. 



Pinnse broad.

 The peculiar character which distinguishes this section from Za- 

 mites may be easily remarked by comparing the attachment of the 

 pinnse in any of the above species with that of Z. lanceolatus, ' Foss. 

 Flor.' 3. t. 194. 



Pterophyllum, Brong. 



Fronds pinnate ; pinnse sublinear, inserted by their whole base ; 

 apex truncate, sometimes acute ; veins fine, equal, slender, parallel, 

 but little marked.
