cancellated appearance. Epidermal cuticles separated by maceration are 
strong and thick and marked by nearly straight-walled, rectangular to 
quadrate, epidermal cells. No traces of stomata were observed on either 
surface. This remarkable circumstance considered together with our 
ignorance of the mode of fructification precludes any justifiable reference 
to the modern fern genus Oleandra. The presence of a thick cuticle and 
of abundant strengthening tissue would not suggest that the narrow 
blades are leaves of a water plant. But until further evidence is gathered 
it would be premature to speculate upon the systematic position of this 
interesting form. Comparisons were made .with grass-like blades from 
Kootenay strata of western Canada referred by authors to Oleandra 
graminaefolia, and the conclusion was reached that the material is speci- 
fically identical.

Material is little more than fragments. Pinnules are small, much 
contracted at base, deeply cut into two or more oblique pairs of lobes. 
Individual lobes narrowed at base and somewhat club-shaped, except 
those near apex of pinnule which are acutely pointed with a broadly 
acute apex. One vein enters each pinnule obliquely from the midrib of 
the ultimate pinna and from this a single branch goes off obliquely into 
each lobe. The latter are single or bifid, corresponding to whether the 
margin of the lobe is entire or divided. 
Stomata are abundant on the lower surface of a pinnule. Fructi- 
fication and hence systematic position unknown.
