with those described fromQuedlinburg, 'Saxony;.by',Heei" as
Geinitzia [ormosa and :by Newber_yand the writer as Sequdii_
gracillima. These cones are not always pyritik_d, but are sometimes
simply lignified add flattenec[ in:the clays, and in the:latter
state they are distinguishable.with difficulty from. the specimens:
labelled Microzamia gibba in the collections of the N. Y.. Botgn:,
ical Garden. Foliage se6mingl_r cot:rectly identified as that of
Gdnitzia [ormosa has been recorded froh:t "Woodbridge by Newberry
and from Cliffwood Bluff by7 thewriter, so that the presumption
is strong that Newberry's Microzamla gebba really is
Ge_nitzic_ formosa. Because I have been unable to find Newberry's
types or to settle the question beyond reasonable doubt,
and influenced somewhat by the fact that the cones called
Geinltzia formosa or Sequoia gracillima are so very abundant irt,
and characteristic of, the overlying Magothy formation, I have
not thought it wise to make any change in name at the present
time.
