66 CONIFERAE. 



fossil from the Miocene beds of Spitsbergen and Grinnell-land. The leaves 

 are essentially like those of Phoenicopsis ; they have scars at their base at 

 the point of separation, and several nerves. They do not however grow on 

 short shoots, but are found attached in spiral arrangement to a piece of a 

 branch. Hence since the resemblance to Phoenicopsis is in the ribbon-like 

 leaves only, and the two forms belong to so widely separated formations, it 

 seems to me a somewhat violent proceeding to unite them ; the comparison 

 with section Nageia of Podocarpus suggested by Heer is more promising. 

 Schenk l has described under the name of Eolirion primigenium a branch 

 from the lowest beds of the Chalk of Wernsdorf in the Carpathians, which 

 is closely beset with large ribbon-like leaves. He has since referred it to 

 Phoenicopsis 2 , from which it is essentially distinguished by having no short 

 shoots. It seems to me that in Eolirion and Feildenia we have before us 

 representatives of forms which we cannot yet determine from want of 

 material. We must wait for future fortunate discoveries, especially in the 

 Chalk. 



Other genera, usually referred by authors to this group on what seem 

 to me to be somewhat doubtful grounds, are Ginkgophyllum, Sap. Whit- 

 tleseya, Lesq., Trichopitys, Sap., Dicranophyllum, Grand' Eury. In Ginkgo- 

 phyllum, the type of which is G. Grasseti, Sap. from the Permian beds of 

 Lodeve figured by Schenk 3 , somewhat irregularly incised leaves like those 

 of Ginkgo or Baiera are attached to an elongated branch, on which their 

 insertions run a long way down. There is no indication that the stalk was 

 channelled, nor is there any evident point of separation. Saporta 4 reckons 

 among species of this genus a lobed leaf-fragment from the Permian of the 

 Ural, Ginkgophyllum Kamenskianum, Sap., and also a form from the 

 English Coal-measures, G. flabellatum, Sap. (Psygmophyllum, Schpr), 

 which is figured in Lindley and Hutton 5 as a species of Noggerathia. 

 Some single short-stalked leaflets ending above in an obtuse toothed margin 

 have been described by Lesquereux 6 under the name of Whittleseya, and 

 are figured also in Renault 7 , but they are for the present of no value to the 

 botanist. The type of Trichopitys is also a fossil from the Permian beds of 

 Lodeve, T. heteromorpha, figured by Saporta 8 . This is a branch with 

 elongated internodes, and leaves which split up by repeated dichotomy into 

 fascicles of fine linear divergent lobes. At the base of a lateral branch 

 which has been preserved the leaves are abbreviated and little or not at all 

 divided. In the axils of the leaves are seen here and there stalked bud-like 

 forms, which Saporta 9 has since sought to explain as ovules. I saw in Paris 

 at the Ecole des Mines a specimen agreeing with Saporta's figure. The
