CONIFERALES. 79 



with those described from Qnedhnburg, Saxony, by Heer as 

 Geinitzia formosa and by Newberry and the writer as Sequoia 

 gracillima. These cones are not always pyritized, but are some- 

 times simply lignified and flattened in the clays, and in the latter 

 state they are distinguishable with difficulty from the specimens 

 labelled Micro zainia gibba in the collections of the N. Y. Botan- 

 ical Garden. Foliage seemingly correctly identified as that of 

 Geinitzia 'formosa has been recorded from Woodbridge by New- 

 berry and from Cliffwood Bluff by the writer, so that the pre- 

 sumption is strong that Newberry's Microzaniia gibba really is 

 Geinitzia formosa. Because I have been unable to find New- 

 berry's types or to settle the question beyond reasonable doubt, 

 and influenced somewhat by the fact that the cones called 

 Geinitzia formosa or Sequoia gracillijua are so very abundant in, 

 and characteristic of, the overlying Magothy formation, I have 

 not thought it wise to make any change in name at the present 

 time. 



Occurrence. — Woodbridge.

Description. — Discoid fruits almost circular in outline from 6 

 mm. to 12 mm. in diameter, sometimes slightly emarginate on 

 one side at the point which Professor Newberry believed to be 

 the point of attachment, but which is probably the distal micro- 

 pylar extremity. As usually preserved the impression shows two 

 concentric circles i to 2 mm. apart, the inner representing the 

 outline of the inner seed coat and the outer layer the slightly 

 fleshy external coat.
