Additions to the fossil flora from Cliffwood, New Jersey

(With plates i and 2) 



The following notes are based for the most part on rather in- 

 definite remains of vegetable origin, most of which have washed 



of the Cretaceous clays at Cliffwood, N. J., by the action of 

 the waves. Fossil-bearing layers in the clays which go to form 

 the cliff at this locality have been so obscured by landslips, caused 

 by the sea eating into the bluff, that good collections are not to 

 be had at the present time. 



Previous contributions by Dr. Arthur Hollick * and the 

 writer f have given a fair idea of the flora of this horizon, and 

 render the present condition of the exposure less regrettable than 

 would otherwise be the case.

Microzamia (?) dubia sp. nov. Plate i, figure 2 



This appears to be the central axis of a small cycadeous fruit- 

 spike or similar body of unknown affinity, from which the fruit 

 bodies have been shed or macerated, leaving a regular ascending 

 series of rounded pits about 1.5 mm. in depth, with thin sides 

 tending to a hexagonal outline at the surface ; across the bottom 

 of nearly all of the pits is a thin transverse wall projecting Into 

 the cavity, in some cases nearly to the surface. 



Our specimen is much smaller than the remains of Micro::auiia 

 gibba (Reuss) Corda which are of common occurrence in the 

 Raritan at Woodbridge, N. J., and does not compare closely with 

 Newberry's figures,;]; which are not particularly good, however. 



The Cliffwood specimen is silicified and not in the least compressed, 

 whereas the remains in the Woodbridge clays are all flattened 

 and carbonaceous. The resemblance to the central axis of Corda's
