OF BRITISH COLUMBIA AND THE NORTH-WEST. 28 
at angle of about 60°. delicate, flexuous, netting and branching toward margin. Base 
gradually narrowing to a wide and at first bordered petiole. Apex not seen. The smaller 
specimens of this leaf are not unlike those of the modern M. acuminata. Some of the leaves 
are, however, twice as large as that figured, and with the angle of venation rather less 
acute. 
Collected by Dr. G. M. Dawson at Coal Brook. 
16. MENISPERMITES RENIFORMIS, 8S. N. (Fig. 12.) 
Leaf broad, reniform, 11 centimetres broad and 7 centimetres in length, margins 
undulate. Five veined, but with two accessory veins, making 7 in all. This is a very 
remarkable leaf, but of somewhat uncertain affinities. 
Collected by Dr. G. M. Dawson at Coal Brook. 
17. PROTOPHYLLUM LECONTEANUM ? 
Lesquereux, Cretaceous Flora, p. 103, pl. XVI. 
This leaf is very imperfect, but approaches nearly in its venation to the species named. 
Collected by Dr. Selwyn at Peace River. 
18. PROTOPHYLLUM BOREALE, N. N. (Fig. 13.) 
Leaf very large, rounded at base, which extends 2 to 5 centimetres beyond the attachment 
of the petiole. Venation based on three main ribs, springing from the midrib near its base, 
and which are connected with each other by veins angling upward. The lateral veins give 
off regular secondary veins toward the margin. The portion figured is the basal part of a 
large leaf, which some fragments show to have been six inches or more in its greatest 
diameter. 
Collected by Dr. Selwyn at Peace River. 
19. PROTOPHYLLUM RUGOSUM. 
Lesquereux, Cretaceous Flora, p. 105, pl. XVII. 
A leaf not very well preserved, but so far as can be seen not distinguishable from that 
above named, which is from the Dakota Group. 
Collected by Dr. G. M. Dawson at Coal Brook. 
Additional Inland Species. 
20. Pinus SUSQUAENSIS, 8. N. (Pl. IL, Fig. 37.) 
Leaves, long linear, about 3 inches in length, and 8 or more in breadth, replaced by a 
micaceous mineral in hard black slaty rock. 
21. LAURUS CRASSINERVIS, S. N. 
A narrow lanceolate leaf, resembling L. Nebrascensis of Lesquereux, but more parallel- 
sided and with very strong channelled midrib, haying transverse wrinkles. No trace of finer 
venation. 
Both of the above species are from the deposit in Susqua River already referred to, and 
believed to be of Cretaceous age.
