Locality
From Hollick (1930) (p. 45-46)
"Yukon River, north bank, about 15 miles below mine No. 1 (original No. 3AH32); collected by Arthur Hollick and Sidney Paige in 1903 (lot 3271)."
Description
From Hollick (1930) (p. 45-46)
"Frond large, dimensions not known, pinnate; pinnae linear, approximately 3 to 4 millimeters in width, apparently abruptly expanded and contiguous at the bases, subtending obtuse, almost right angles with the stout rachis; nervation simple, parallel, about six nerves to each pinna. "
Remarks
From Hollick (1930) (p. 45-46)
"This specimen is evidently a fragment of a large cycadaceous frond with a very thick central rachis. Apparently it is the under surface that is represented; but the remains are so poorly preserved that critical details are not determinable. The arrangement of the pinnae is so obscurely defined that it is impossible to determine satisfactorily whether they are attached to the sides or to the upper surface of the rachis. The general aspect and gross characters of the specimen, however, are indicative of the genus Pterophyllum and apparently of a heretofore undescribed species."
