It seems probable that it is the species that suggested Platanus which 
Dawson mentions 1 in his report on the plants from Burrard inlet, as the 
large proximal fragments in the collection from Kitsilano much resemble 
that genus. It resembles somewhat Hicoria magnified, Knowlton 2 from 
the Upper Eocene of Kukak bay, Alaska, but is less elongate, lacks the 
cuneate base, has less ascending secondaries and larger teeth. It may be a 
descendant of the Fort Union Celastrus curvinervis Ward 3 .

This species, based upon fragmentary leaves, and fruits, from the 
Kenai beds of Alaska, was described by Heer. To it should be referred 
the maple fruit described by Dawson from Stump lake, Similkameen 
valley. Both leaves and fruit, identical with the type material, are con- 
tained in the collection from Joseph creek. 
Penhallow has recorded fruits or leaves of the maple from Horsefly 
and Tulameen rivers and Quesnel, B.C., under the names of Acer dubium 
Penhallow, Acer grosse-dentatum Heer, Acer trilobatum productum Heer, 
and Acer sp. Dawson, but as they are very inadequately described, and 
are not figured, it is impossible to state their relationship to this species, 
although it is very probable that some of them are identical with it, rather 
than with the forms to which they have been referred. 
Order, Rhamnales 
Rhamnus kitsilaniana Berry n. sp. 
Plate XIX, figure 1 
Leaves of relatively large size, ovate-lanceolate in outline,- widest 
medianly, and curving almost equally distad to the acuminate tip, and 
proximad to the slightly decurrent base. Margins entire, evenly rounded. 
Texture thin. Length about 12 cm. Maximum width about 4 cm. 
Petiole short and stout. Midrib stout, prominent, curved. Secondaries 
about 5 pairs, mediumly Btout, alternate, somewhat irregularly spaced; 
they diverge from the midrib at angles of about 45 degrees, and curve 
immediately upward in regular sweeping curves, subparallel with one 
another and with the leaf margins. Tertiaries thin, percurrent, and 
mostly obsolete.
