This is a distinct type, whose variations are well shown in the accom- 
panying figures. It is not especially close to any previously described 
forms, and comes from Joseph creek, where it is not uncommon. It is 
possible that Betula sp. from Kitsilano represents an abnormal leaf of this 
species.

This species was described from the Upper Clarno beds of Bridge 
creek, Oregon, and was recorded by Penhallow from Quilchena, B.C. It 
is contained in the collection from Kitsilano.

It seems hopeless to attempt to reduce to a rational interpretation the 
large number of forms from numerous localities and horizons that have 
been referred to this Old World Miocene type. There are large numbers 
of leaves in the collection from Joseph creek, and they are also present from 
Darlington creek and Kitsilano. Similar forms have been previously 
recorded from Quilchena, Stump lake, Similkameen, Tulameen, and 
Tranquille rivers, B.C.; from the Eocene of Birch bay, Washington (state) ; 
and from the Kenai formation of Alaska; as well as from beds of similar 
age in Greenland and elsewhere. 
Attention should be called to the resemblance of these forms to the 
existing Carpinus seemeniana Diels of central China. 
Alnus cremastogynoides Berry n. sp. 
Plate XVI, figure 1 
Rather elongated leaves of medium size, widest medianly, rounded 
upward to an obtuse tip and downward to the narrowly cuneate base. 
Margins entire in the lower two-fifths, above which they are beset with 
prominent aquiline-serrate teeth. Texture sub-coriaceous. Midrib stout, 
prominent on the lower surface of the leaf. Secondaries numerous, sub- 
parallel and camptodrome. 
This species, clearly new, is of special interest since it is almost identical 
with the existing Alnus cremastogyne Burkill, a species with a restricted 
range in the mountains of central China (province of Sze-ch’uan), in fact 
it is much more like this species than it is like any existing American species 
of Alnus, although it is something like some of the leaves of Alnus rhombi- 
folia Nuttall of western United States. It comes from Newhykulston creek.
