Description of the Specimens. —There are several specimens in the New Zealand Survey 
collections from Waikawa, which appear to represent a new species of Podozamites. 
None of these, however, are at all perfect. A photograph of one, showing the general 
habit of the leafy shoot, is reproduced, natural size, as fig. 11. Fig. 12 is a drawing 
of another example, in which the individual leaves attached to the stem are seen 
more clearly. 
Remarks. —-This plant appears to be a very distinct species, characterized by the 
narrow linear leaves. In the British Jurassic type, Podozamites lanceolatvs (L. & H.), 
the leaves are much broader and more lanceolate in form. In the common Rh actio 
species of Australia, P. elongatus (Morr.), the leaves are also broader and more 
elongated. 
In 1868 Eichwald(l) figured a leaf from the Jurassic of Russia under the name 
Zamites angustifolius sp. nov. Judged by his figure, this specimen is probably more 
oorrectly assigned to Zamites than to Podozamites, to which, however both Heer and 
Schimper(2) have referred it. The base of the leaf is clearly decurrent, and the 
general habit is much more like that of a Cycadean frond than of a shoot bearing 
spirally arranged leaves. Heer(3) has, however, referred some further plants from 
Siberia to Eichwald’s species, as Podozamites angustifolius (Eichw.). Some of these 
approach Podozamites gracilis somewhat closely, though the leaves appear to be shorter 
and rather different in shape. 
Type. —-New Zealand Geological Survey collection. 
Occurrence. —Curio Bay, Waikawa (Middle Jurassic).
