28 J. W. DAWSON ON CRETACEOUS AND TERTIARY FLORAS 
diverging at a very acute angle from the base. Usual length, about 5 centimetres. Leaves 
of this type are found at Baynes’ Sound and Vancouver Island ; but too imperfectly pre- 
served to admit of any certain distinction from described species. 
27. JuGLANS HARWOODENSIS, 8. N. (Fig. 31). 
Leaf ovate, narrowing toward the base. Midrib distinct ; veins at a very obtuse 
angle, nearly 80’, curving and netting at margin, which seems to be slightly toothed. 
Breadth, 4 centimetres ; length, probably 11 centimetres. 
Collected by Mr. J. Richardson, at Harwood Colliery, Nanaimo. 
28. Diospyros VANCOUVERENSIS, NS. N. (Fig. 32). 
Oval, pointed at base, obtuse and oblique at apex. Margin, entire or slightly undulate. 
Midrib and veins strongly marked ; angle of divergence of veins from midrib, abut 60°. 
Veins curved strongly and uniting at the margin. Veinlets transverse, straight, giving a 
coarse rectangular reticulation. Length, about 5.5 centimetres; breadth, 3 centimetres. 
Collected by Mr. J. Richardson, at Nanaimo. 
29. CEANOTHUS CRETACEUS, NS. N. (Fig. 33). 
Regularly elliptical, with three principal veins, the lateral ones curving regularly from 
base to apex. Margin, crenulate. Minor venation, obscure. Length, 5 centimetres ; 
breadth in middle, 2.6. Distance of lateral veins from midrib in middle, 0.8 centimetre. 
The modern C. Americanus has very similar leaves, but broader in proportion. C. ovalis has 
narrower leaves. This ancient leaf is thus between the two. This leaf might be included 
in the genus Cinnamomum, as defined by fossil botanists; but I cannot distinguish it from 
the foliage of the modern genus Ceanothus, still living in the west. 
Collected by Dr. G. M. Dawson, at Baynes’ Sound. 
30. ANISOPHYLLUM, Sp. (Fig. 34). 
Apparently a soft, fleshy leaf, with strong midrib, and giving off a large branching 
vein at one side near the base, and more slender and simple veins elsewhere. Length, 
about 7 centimetres ; breadth, about 4. Margin, entire. 
Collected by Dr. G. M. Dawson, at Baynes’ Sound. 
31. PROTOPHYLLUM NaANAIMO, S. N. (Fig. 35). 
Large, 16 centimetres or more long, and 12 in breadth. Veins very nearly opposite, 
and at an angle of 55’ to the midrib. Interspaces with transverse veinlets more or less 
netted and curved, or angled upward. Approaches to P. leconteanum of Lesquereux, from 
the Dakota group. 
Collected at Nanaimo by Mr. J. Richardson ; at Baynes’ Sound, by Dr. G. M. Dawson. 
32. ALNITES INSIGNIS, NS. N.. (PI. viii., Fig. 38.) 
Leaf coriaceous, shining, somewhat triangular or broad cuneate, rounded and coarsely 
toothed above; smaller and distant teeth on the sides; narrow at base and rapidly 
widening. Midrib straight, well marked, veins about equally strong, very slightly curved, 
diverging from the midrib at an angle of 50° and running direct to margin, nearly parallel 
to each other. Veinlets straight, simple, at right angles to the veins. Lateral margins,
