three nerved, the veins about ? — 3 imm. distant, the chiefly obscure 
cross veins either wholly transverse or diagonal. 
This diagnosis is based upon one fairly well preserved specimen 
of which the basal lobes are wanting, and upon three other less com- 
plete fragments which show a much less perfect state of preservation, 
inasmuch as they show no veins, or at the best exhibit them but 
obscurely. That this leaf is that of an endogen admits of no doubt, 
and a comparison with the leaves of existing species soon served to 
establish a general resemblance to those. of Maianthemum bifolium 
dilatatum. The leaves of this species vary somewhat widely as to 
their form and the development of the basal sinus, but the following 
may be taken to represent the essential characteristics so far as they 
could be obtained from a number of herbarium specimens. 
Leaf broadly ovate, about 7 cm. broad, and upwards of 10 cm. 
long from the base of the sinus to the apex. Sinus broad and shallow 
or upwards of 3 cm. deep. Margin entire; the apex acuminate or 
abruptly acute. Nerves about 11, somewhat prominent toward the 
base, but becoming obscure and finally obsolete toward the apex; the 
interval variable, but at the point of curvature toward the apex, 
about 5 mm. distant; the veins about 1 mm. distant. 
From the above descriptions, it would seem that our fossil has 
its nearest representative among living plants in Maianthemum 
bifolium, and it should therefore be referred to the genus Majan- 
themophyllum of Weber. The very large size of the leaf suggests 
the propriety of grandifolium for the specific name. Of Tertiary 
representatives of this genus, Schimper enumerates four species as 
common in Europe,! and Hollick has described one ?— M. pusillum — 
from the Cretaceous of Staten Island. As given by Schimper, and 
as defined by the figure of M. pusillum given by Hollick, there seems 
to be no essential point of agreement with the Red Deer River material, 
which represents a different specific type and requires to be separately 
designated.
