Bulletin 3. The flora of the Raritan Formation, 1911 - State of New ...

FILICALES. 69
This species was described originally by Heer from the Kome
beds of Greenland and was subsequently identified, by the same
author from the much later Atane beds; Dawson reports it from
a number o,f localities irt the Kootanie of British Columbia, and
Fontaine and Ward describe it from the Lower Cretaceous of
the Black Hills. It is also reported by both Lesquereux and
-Ward from the Dakota Group and by Kurtz from Argentina.
It seems very doubtful if these can all be the same plant, and the
gelogical range alone suggests that the earlier and the later forms
may be distinct. The Lower Cretaceous forms certainly suggest
a relationship with those wide-spread types of sterile fronds
.variously identified as Thryrsopteris or Onychiopsis, while those
from the Upper Cretaceous suggest Anemia rather than Asplen-
'i_m. However, in the absence of representative material from
the different horizons, it seems unwise to attempt any segregation
at the present time.
The specimens from the Raritan are abundant at the Woodbridge
horizon and many excellent figures are given by Newberry
in his Flora of the Amboy Clays.
