Other fossils, to which these same remarks would apply, 

 are according to Arber: Eolirion primigenium Schenk from 

 the Wealden, Krannera mirabilis Velenovsky from the Cre- 

 taceous and perhaps Zamites megaphyllus (Philltps) from the 

 Oolite. 



The Swedish specimen differs from the plants mentioned 

 above by narrower leaves, which are also more tapering to- 

 wards the base. In the coal-bearing beds of Scania there 

 have been found some detached leaves very similar to those 

 of the present plant. Some of these leaves have been de- 

 scribed by Prof. Nathorst * under the name Phoenicopsis cfr. 

 speciosa Heer, and they certainly very much resemble, in 

 shape and venation, the leaves of that species. It is pos- 

 sible, however, that at least a good deal of these leaves may 

 have been borne directly on stems of the same kind as that 

 described above. Phoenicopsis, as defined by Heer 2 , would 

 embrace only plants with the leaves borne in tufts on short 

 shoots, which were surrounded by scale-fronds and shed entire 

 as in Czekanoiuskia. Unquestionable Phoenicopsis, showing the 

 leaves attached on short shoots, has not yet been recorded 

 from Sweden. 



Salfeld 3 has recently described, from the Jurassic of 

 Northern Germany, a leaf-bearing stem, under the name 

 Phyllotenia longijolia nov. gen. et sp. This plant reminds, in 

 the shape and venation of the leaves, of both the Swedish 

 specimen and the species of Phoenicopsis. The leaves are 

 said to be attached directly on the stem and probably spir- 

 ally arranged. Salfeld's figure gives however no clear idea 

 of the mode of attachment of the leaves, and no leaf-scars 

 are seen. The new genus is classed by the author under the 

 Ginkgoales, mainly, as it seems, from the occurrence of Ginkgo- 

 like seeds. The reasons for attributing these seeds to the 

 leaf-bearing shoot do however not appear, neither in the de- 

 scription nor in the figures. 



In order to avoid the creation of a new provisional 

 generic name, I have attributed the Swedish specimen to
