Descriptio_,--Twigs of a conifer, represented in clays by
crowded cylindrical branches of graceful aspect and slender forking"habit.
The leaves are reduced almost to the vanishing point,
in fact most specimens fail to show any traces of leaves whatever,
and it is possible that these spiirally-arranged scale-like
leaves o.f Newberry's description may have been founded upon
deceptive material.
These twigs are unjointed, an objection against their former
reference to the genus Fre_relopsis. It has been suggested that
they represent decorticated specimens of Widdringto_dtes Reichii
(Ettings.) Herr, which is so common in the Raritan and over-'
lying Magothy formation. The present species is recorded from
bc_h Delaware and MarD_land.
Hollick and Jeffrey have shown (loe. eft.), since the foregoing
was written, that the present species is not related to Frenelopsis,
but constitutes a distinct genus.
