V. 2399. Small fragment of pinna. Ecclesboume. Rufford Coll. 



v. 2345 and V. 2345^2. Small piece of racliis with a few pinnae ; 

 somewhat intermediate in form between PI. IX. Pig. 2 and PI. VII. 

 Pig. 5. Ecclesboume. Rufford Coll. 



v. 2375. A single pinna, 3 '6 cm. long, of uniform breadth; 

 pinnules show faint traces of venation which may possibly be of

Genus TEMPSKYA, Corda. 



[Flor. Vorwelt, 1845, p. 81.] 



Corda proposed this term for four specimens of fossil ferns dis- 

 covered by Tempsky. 



He included the genus in the family Phthoropterides, and defined 

 it as follows : — 



" Truncus .... Ehachis rotundata, plioata vel alata, cortice 

 crassiuscula, faaciculis vasorum ternatis, majori clause vel lunulato 

 et supra incurve, minoribus oppositis luuulatis. Eadices minutae 

 numerosissimse ; fascicule vasorum central! unico." 



The older name Endogenites, used by Sprengel ' and Brongniart ' 

 in 1828, was chosen by Stokes and Webb ' for Mantell's specimens, 

 which have since been referred to Corda's genus, as expressive of 

 their opinion that the fossils were pieces of some Monocotyledonous 

 stem. Mr. Starkie Gardner* in alluding to certain examples of 

 " Endogenites" in the British Museum, to which Mantell probably 

 referred in his remarks on Monocotyledonous stems in the English 

 "Wealden, speaks of them as "of course Cycadeous." If he 

 refers to the common form of Endogenites erosa, there can be no 

 question of Cycadean aflS.nity ; the structure is undoubtedly that of 

 a fern. It would be difficult to give any satisfactory definition of 

 the genus Tempshya ; and seeing that such specimens as are
