"Plate 2, Figure 6"

"Pinnule apparently elliptical or elliptical-spatulate, entire; nervation consisting of a network of reticulations that begin in an obscurely defined central nerve or midrib at the base of the pinnule and extend upward and outward to the margin."



From Hollick (1930) (p. 41)

"The basal portion of our specimen is not preserved, hence the basilar outline can not be defined. The upper part, however, is symmetrical, and this is probably the character of the pinnule as a whole. It is suggestive of specimens from the Shasta series of California, referred by Fontaine (1905) (p. 233, pl. 65, figs. 30 - 35) to Sagenopteris mantelli (Dunker) Schenk (1871) (p. 222 (20), pl. 31 (10), fig. 5) from the Wealden of Germany, and although it appears to be probable that the Alaska and California specimens are specifically identical it is doubtful if either of them is identical with Sagenopteris mantelli, in which any indication of a main central nerve or midrib is entirely lacking."
