Fig. 794, G, C' repre- sents a type from Bournemouth described as Podocarpus mcerte which differs from other species in the absence of a definite midrib; the linear-lanceolate coriaceous leaves, reaching a length of 3 cm., are decurrent and appear to have several parallel veins, a feature characteristic of the section Nageia: /iti^ Fig. 793.

Some leaves figured by Schmalhausen* from Oligocene strata in Russia as species of Podocarpus are too imperfect to afford any trustworthy evidence as to the occurrence of the genus Podocarpites.
