Description.--"Z. foliis magnis, foliolis elongato-lanceolatis,
23 ram. latis, apicem versus sensim angustatis, multinerviis, late
et fortiter marginatis." Heer, 1882.
Leaflets large, 15 cm. to 2o cm. in length by 2. 3 cm. to 4 era.
in breadth, Ianceolate in outline, somewhat falcate. Apex obtusely
pointed. Proximally somewhat abruptly narrowed to an
apparently thickened base. Veins numerous, close, fine, parallel.
Remains of a large parallel-veined leaf, apparently a leaflet of
Podoza_ites, are not uncommon in the Raritan deposits, although
unfortunately they are usually fragmentary. They seem to be
identical with the type material of this species described by Heer
from the Atane beds of Greenland, which ranges southwards
along the Atlantic coastal plain as far as Alabama.
Occurrence.--Woodbridge.
Collectiona.--N. Y. Botanical Garden.
