Juglans nigelloides Berry n. sp. 
Plate XI, figures 5, 6 
Leaflets ovate-lanceolate in outline, markedly inequilateral, parti- 
cularly at the base, which is rounded on one side and rather straightly 
ascending on the other. Tip somewhat narrowed and acuminate. Margins 
with fairly large, not very prominent, rounded-dentate teeth. Texture 
sub-coriaceous. Length about 11 cm. Maximum width, in the lower 
part of the leaf, about 3 cm. Petiolule short and stout. Midrib stout 
and prominent. Secondaries stout, and prominent on the under side 
of the leaflet; numerous, sub-equally spaced, and sub-parallel; they diverge 
from the midrib at angles of about 60 degrees in the broader half of the 
lamina and at a somewhat less angle in the narrower half; they pursue 
rather straight courses and curve near the margins to become eamptodrome; 
short curved tertiary branches run to the marginal teeth. The balance 
of the tertiaries are well marked, but not prominent; they have the appear- 
ance of being percurrent, which they are in part, but frequently there is 
an astomosis in the median region between the secondaries. 
This is an exceedingly well-marked species, which shows unmistakably 
the characters of Juglans. It resembles the rather widely distributed 
Juglans nigella Heer, which resemblance has suggested its specific name, 
but always showing consistent differences, which in my judgment mark 
it as a distinct species. Juglans nigella was described by Heer from the 
Upper Eocene of Alaska 1 , and subsequently recorded from Greenland 
and eastern Asia, as well as various localities in North America. The 
present species from the Puget group at Burrard inlet differs from Heer's 
type in being somewhat smaller, with less ascending and straighter second- 
aries, and obtusely dentate instead of serrate margins. It differs in much 
the same way from Lesquereux’s identification from the Fort Union for- 
mation, which may not be that species. 2 Knowlton’s identification 3 from 
the Raton formation appears to be correct, and the British Columbia 
species differs from it in the same features that it does from Heer's type, 
the Raton form having still more pronounced serrate teeth. Newberry 
also recorded Juglans nigella from Alaska 4 but his form is not even a 
Juglans, but a Quercus, and is quite different from the type. Both Daw- 
son 6 and Penhallow® have recorded Juglans nigella from the Tertiary of 
British Columbia, but whether these last represent that species or this 
new species described above it is impossible to say.
