This species was first described by Phillips[743] from the Middle Jurassic Stonesfield Slate and afterwards referred to _Zamites_[744]: the leaves bear a striking resemblance to foliage of the type _Cordaites borassifolius_; the lamina is 30 cm. long and attains a breadth of 3 cm., the apex is acuminate and slightly contracted towards the broad concave base. My former comparison of these Stonesfield leaves with the long pinnae of _Ceratozamia mexicana_ seemed to be supported by Phillips’s type-specimen of _Palaeozamia longifolia_. It may be that the supposed pinnae in Phillips’s type are spirally disposed leaves: if this is the case the specimen may be a fragment of a _Podozamites_; its specific identity with the larger detached specimens, though probable, cannot be demonstrated. Some leaves figured by Zigno[745] from Jurassic rocks of Italy as _Yuccites Schimperianus_ may be identical with _P. megaphylla_. _Pelourdea mirabilis_ (Velenovský ex Corda +MS.+). The generic name _Krammera_, suggested by Corda, was employed by Velenovský[746] for large _Cordaites_-like leaves from the Lower Cretaceous of Bohemia, for casts of cones regarded by him as stems, and for fruit-like bodies. The leaves, previously described as _Flabellaria chamaeropifolia_ Goepp., _Dammara albens_ Presl, etc., bear a close resemblance to the large broadly linear leaves of _Cordaites_; the lamina reaches a length of 40 cm. and between the veins occur 1–4 finer striations. The fossils identified by Velenovský as stems bearing crowded imbricate scales, which he regarded as the persistent bases of _Krammera_ leaves, are probably cones; they agree very closely in size and shape, also in the form of the scales, with cones of _Agathis_ and some other recent Conifers. As the designation _Krammera_ was instituted primarily for cones and not leaves the name _Pelourdea_ is substituted for it. =Niponophyllum.= Stopes and Fujii. _Niponophyllum cordaitiforme_ Stopes and Fujii.
