There are fragments of several fronds in the
collection that should probably be referred to this species, yet they do
not quite agree in all particulars. Thus the example secured by Bendire
(U. S. Nat. Mus., No, 2634) has the frond from 4.5 cm. to nearly 5 cm.
in width, while a specimen obtained by the University of California (No.
170, counterpart 171) is only 2.5 cm. in width. These measurements are
larger and smaller respectively than the usual examples of A.
subsimplex from Colorado, and the nervation arises at a less angle
in the Oregon specimen, but these differences are slight and probably
not sufficient to exclude them from this species.
Locality.Cherry Creek, Crook County,
Oregon. Collected by Maj. Charles E. Bendire (U. S. Nat. Mus., No.
2634), by Merriam's party in 1900 (Mus. Univ. Cal., Nos. 170, 174), and
by Knowlton and Merriam, 1901 (U. S. Nat. Mus., Nos.
90689074).

This species appears to have been found but once. The
specimen is now in the United States National Museum and is preserved in
matrix which closely resembles that at Cherry Creek.

have since been obtained.
