Descriptioih. — Leaves or leaflets ovate to ovate-lanceolate in 

 outline, with entire margins, emarg-inate apex and cuneate base, 

 varying from 5 cm. to 10 cm. in length, and fromi 3 cm. to 5 cm. 

 in breadth. Midrib, stout. Secondaries stout, numerous, camp- 

 todrome; their intervals filled by more or less parallel, reticulat- 

 ing fine tertiaries. The angles of divergence are variable even in 

 the same leaf, and the exigencies of preservation obscure the 

 finer venation in some specimens, which give them a strikingly 

 different appearance from others in which the preservation is 

 more complete. 



These leaves are very variable in size and outline. The apex 

 is often angular at the corners of the leaf-blade and at the sinus, 

 at other times it is rounded. The sinus may be shallow or 

 moderately deep. The leaflets are miuch wider than in the 

 following species, and the width is usually greatest in the upper 

 part, although this feature is far from constant.
