"Coal Bluff, Herendeen Bay, Alaska Peninsula (original No. 31); collected by W. W. Atwood and H. M. Eakin in 1908 (lot 5185)."
Description
From Hollick (1930) (p.77)
"Leaf of unknown shape and dimensions, sharply and irregularly dentate; nervation apparently flabellate, craspedodrome, the nerves forked, the branches terminating in the dentitions; secondary nervation fine, transverse, simple, forming a series of irregular, quadrangular areolae with the primaries."
From Hollick (1930) (p.77)
"This fragment of a leaf is evidentluy laterally compressed and wrinkled, so that the nervation appears to be contorted. The long, conspicuously forked nerve in the middle of the leaf, as represented in the figure, may be a main nerve or midrib extending into an acuminate apex; but this is merely a conjecture, based upon indications that are not conclusive. The secondary nerves, which appear to be bent and to diverge from the primaries at various angles, are probably uniform in arrangement under normal conditions.
This specimen is given a distinct specific rank, although it may be identical with C. inordinatus, the species last described, and perfect specimens, if brought to light in the future, may prove them to belong to one and the same species. The secondary nervation appears to be rather peculiar; but this feature is so obscurely defined in the other species of the genus that satisfactory comparison is impossible. The irregularly sharply dentate margin may be compared with that of the living Castalia ampla Salisbury."
