26 J. W. DAWSON ON CRETACEOUS AND TERTIARY FLORAS 
14. PHRAGMITES CORDAIFORMIS, 8. N. (Fig. 22.) 
An inch or more in width when full grown. Parallel veins distant from each other 
about 5 millimetres, and with some intervening striæ. Resembles P. Cretaceous, Lesq., from 
Nebraska, but differs in venation. To the naked eye this leaf very closely resembles 
Cordaites borassifolia of the coal formation. 
Collected by Mr. James Richardson, at North Saanich and Nanaimo, and by Dr. G, M. 
Dawson, at Baynes’ Sound. 
15. SABALIMPERIALIS, 8. N. (Fig. 23.) 
Sabal, Sp., Newberry, Boston Journal, Vol. VIL, No. 4. 
Midrib elongate; more than 16 centimetres long and 1.8 wide; coarsely striate 
longitudinally, perhaps in consequence of pressure. Leaf having folds varying from 8 to 
15 millimetres in breadth, at angle of 55° to 60° at base, more acute upward. Nerves fine, 
30 to 60 on each fold, five or six on each side of the middle being coarser than the others. 
General form and margin unknown, but must have been one to two feet or more in 
diameter of blade. This is undoubtedly the Sabal mentioned by Lesquereux and New- 
berry, as found in fragments in collections from Nanaimo. At the Harwood colliery on 
that island Mr. Richardson obtained large leaves, but on a shale so brittle and jointed that 
it was impossible to secure them entire. 
16. SALIX PACIFICA, S. N. (Fig. 24) 
Leaf elongate, pointed at both ends. Apex somewhat abrupt, base oblique. Length 
8.5 centimetres, breadth in middle 1.3 centimetres. Midrib conspicuous ; margin entire. 
In one specimen a group of leaves appears attached to a slender twig. 
Collected by Dr. G. M. Dawson, at Baynes’ Sound. 
17. POPULUS RHOMBOIDEA, Lesqr. 
Lesquereux. American Journal of Science, Vol. XX VII, p. 360. 
Originally described by Lesquereux from specimens collected by Dr. John Evans at 
Nanaimo. Was described as “ rhomboidal, with the margin irregularly toothed above and 
entire near the slightly decurrent base. Lateral primary veins diverging at an acute angle 
like the secondary ones, and ascending to both corners of the rhomb of the leaf, all strongly 
marked with scarcely visible percurrent veinlets.” It is a leaf with the venation on the 
same plan with that of the modern P. grandidentata. 
Collected by Mr. J. Richardson, at Newcastle Island. 
18. POPULUS PROTOZADACHI, 8. N. (Fig. 25.) 
Closely allied to P. Zadachii, of Heer, in its style of venation and crenated margin, but 
with fewer and more delicate veins and broader form. 
Collected by Mr. J. Richardson, at Newcastle Island. 
19. POPULUS TRINERVIS, 8. N. 
A poplar-like leaf, with three slender veins forking upwards. Very peculiar and 
distinctive, and represented by several specimens but all imperfect at the margins. 
Collected at Nanaimo by Mr. James Richardson, and at Baynes’ Sound by Dr. G. M. 
Dawson.
