Jurassic s^oiuis ; Brachyphylhiin whicli is chiefly a Jurassic 
genus, although it occurs also in the Triassic ; representatives 
of Baiera and the allied genus Selerophyllina which are 
Triassis, Jurassis, and Necomian. 
Podozamites aiignstifoliits (Eichw.) Schimp, which is re- 
corded by ileer from the Jurassic of Siberia and Spitzbergen 
reappears in the Raritan. 
In addition to these ancient types, the Raritan abounds 
in species, oftx?n of common occurrence, which have not been 
detected at ClifTwood. Such examples are Sequoia hctero- 
pliylla Vel., Widdringtonia (two species), Celasfrophylhiin 
(nine species), Myrica (seven species), and species in thirty- 
three other genera which are unrepresented at Cliflfwood. 
Knapp erroneously says that 64 per cent, of the Clififwood 
species arc identical with the Raritan flora at Woodbridge. 
As a matter of fact, in the paper he has criticised only 29 per 
cent, of the plants were represented in the whole Raritan 
formation. 
Further contributions have increased the percentage of 
Raritan species found at Clift'wood to 37 per cent. Against 
this ma}' be placed 44 per cent of forms common to the Ceno- 
manian of this country and Europe, the detailed distribution 
of which may be readily seen in the table of species accom- 
panying this article. 
By far the most common fossils at Cliffwood are Cunning- 
hainites squainosus Heer, Dammara cUffzcoodensis HoUick, 
Sequoia rcichenhachi (Gein.) Heer, and Sequoia gracillinia 
(Lesq.) Newb. Of these, Sequoia rcichenhachi ranges from 
the Neocomian through the Danian, and is a very widespread 
form. The balance are peculiar to Cliflfwood and higher hori- 
zons, thus Cunningha)iiites squainosus ogcurs elsewhere only 
in the Senonian of Saxony. 
The imperfectly petrified cones of Sequoia gracilliiim are 
excessively common at Cliffwood, the writer having collected 
hundreds of specimens not only from the wash on the beach 
but also in place in the clays. They are sometimes very per- 
fectly preserved and are very characteristic objects (see plate), 
yet to my knowledge thc\- have never been detected in the 
Raritan formation, although the latter has been opened up 
everywhere for the clay and been extensively collected over.
