Many linear leaves mostly 1 mm. in breadth, but sometimes a 

 little broader, are found with a strong midrib, on both sides of which 

 we can often observe fine longitudinal striae. Though they are 

 always found scattered and only in fragments, I believe they are to 

 be identified with the species discovered in Spitzbergen and Siberia. 



A fragment of a leaf of this species is also found by the side of 

 Adiantites Heerianns. (Fig. 2, PI. XII). Loc. — Shimamura, Tanimura.

Long linear acuminate leaves, 2-2.5 mm. in breadth, thick in 

 texture and scattered on a stone, agree very well with those described 

 under the above name from Spitzbergen and Siberia. The central 

 vein is tolerably thick, and through a magnifier we can observe in 

 some leaves 3-4 finer longitudinal parallel veins, a fact which was 

 also noticed by Heer (Beitr. 1876, p. 117, VI. XXVIII, fig. 4c). 



Dr. Schmalhausen identifies the isolated leaves described by Heer 

 as belonging to a pine with his Cyclopitys Nordeushjoldi in which the
