44 THE FLORA OF THE AMBOY CLAYS. 
ELAINE ROG ANGEA 
GYMNOSPERMZ. 
Order CYCADACEE. 
PopozamirEs ANGUSsTIFOLIUS (Kichw.) Schimp.* 
Pl. XIII, figs. 1-4. 
Podozamites angustifolius ‘Bichw.) Schimp. Schimper, Paléontologie Végétale, Vol. 
II, p. 160. 
Zamites angustifolius Bichwald, Lethzea Rossica, Vol. II, p. 39, Pl. H, fig. 7. 
Leaves long lanceolate, from 5° to 15° in length by 6™™ to 12™™" in 
width, base narrowed to the short petiole, summit pointed; nervation fine, 
parallel. 
In general appearance these leaves are not unlike some of the many 
forms of P. Janceolatus, but are usually longer, narrower, and more flexuous 
in outline. Taken by themselves they might easily be mistaken for some 
of the leaves of Fontaine’s Nageiopsis longifolia trom the Potomac group, 
but the nerves are much finer and more crowded than in that plant. 
Locality: Woodbridge. 
Popozamites MARGINATUS Heer?. 
Pl. XIU, figs. 5, 6. 
Podozamites marginatus Heer, Fl. Foss. Arct., Vol. VI, Abth. II, p. 43, Pl. XVI, 
fig. 10. 
Leaves 18™ to 20™ long by about 3° in width, lanceolate, obtusely 
pointed at the summit, narrowed to a thickened base. 
This would seem to be the plant figured and described by Heer (loc. 
cit.) and obtained from the Upper Cretaceous rocks of Atane, Greenland, 
although the marginal border, on which he lays stress and from which he 
derives its name, is not visible. Unfortunately, the two specimens we have 
are very imperfect, and we must await the discovery of other material before 
we can satisfactorily make the comparison. We may at least say that the 
' This species appears in Dr. Newberry’s manuscript as P. angustifolius, n.sp., a specific designa- 
tion which manifestly can not stand under the rules of priority. Asit agrees in all essential particulars 
with P. angustifolius (Eichw.) Schimp., I have so designated it.—A. H.
