HJ. MÖLLER AND T. G. HALLE, FOSSIL FLORA OF S.E. SCANIA. 17 



A similar feature has been described in the case of N. poly- 

 morjiha by Nathorst ', who has later expressed the opinion 

 that the dots are caused by resinous grains which are com- 

 monly found in preparations of the leaves of that species. 



Baiera? sp. 



PI. 2, fig. 16. 



The fragment in pi. 2, fig. 16, may possibly represent 

 the lower portion of a leaf of Baiera. It is wedge-like with 

 spreading dichotomizing veins and is broken at both ends. 

 It would appear as if it was branched, which would streng- 

 then the probability of its being a Baiera, but this is not 

 certain. 



Pityophyllum? sp. 



PI. 2, figs. 17, 18. 



The small fragments shown in pi. 2, figs. 17 and 18, 

 appear to represent coniferous leaves of the Pityophyllum- 

 type. The largest specimen has a length of only 15 mm.; 

 the breadth is 1 — 2 mm. In both specimens there is a dis- 

 tinct midrib. 



In the following table all the plant-remains described 

 above from Rödaisberg are enumerated. The distribution of 

 such forms as are to any extent determinable is indicated 

 for some important plant-bearing formations. 



It is seen from the table that of the five forms which 

 are identified or compared with known species three occur 

 in both Rhaetic and Liassic strata, viz. Cladophlebis cf. neb- 

 hensis, Guthiera angustiloha and Sagenopteris cf. Nilssoniana. 

 Of the others Dictyophyllum Milnsteri is typically a Rhaetic 

 species. Cladophlebis lobijolia has its chief distribution in 

 the Middle Jurassic; it has been recorded, however, not only 

 from the supposed Liassic flora of Bagaa in Bornholm but 

 also as probably occurring in the Rhaetic of Tonkin.
