440 BERRY: SPECIES REFERRED TO IHINNFELDIA 
remarks as may be necessary may well be made in considering the 
respective species. 
Protophyllocladus gen. nov. 
Comparatively large leaves, of coriaceous texture ; linear to 
ovate-lanceolate in outline; with entire, somewhat undulate, or 
slightly crenate margins: mostly broader toward the apex: with 
straight narrowly wedge-shaped base: slightly petiolate : midrib 
usually stout below, often becoming obliterated toward the apex: 
secondaries fine, numerous, parallel, occasionally forked, usually 
buried in the parenchyma of the leaf; they leave the midrib at an 
acute angle and run directly to the margins. 
Constituting well characterized remains ranging from the middle 
Cretaceous to the basal Tertiary.

This is a most wide-spread species, ranging in considerable 
abundance from Greenland to New Jersey and west to Kansas and 
Nebraska, in beds of approximately the same age, quite the 
opposite from what would occur if it represented a waning tyPe- 
Originally referred to Phyllocladus by Lesquereux, his type 
figure (f. 72. pl. r, Cret. Flora) is identical in outline with certain 
leaves of the living Phyllocladus asplenifolia Hook. f. (P. rhom- 
boidalis Rich.) in which, however, the larger leaves are crenate, 
while those most like the fossil are somewhat smaller. The f- 
semblance is also markedly close to an undescribed Phyllocladus 
(No. 6282, herb. N. Y. Bot. Gard.) from the Laké Brunner dis- 
trict of the South Island, New Zealand. In this form the leaves
