Schenkt, appear to be sufficient for a fairly accurate determina- 

 tion of the age of the plant-bed. They have all their chief 

 distribution in Rhaetic rocks, occurring, inter alia, in the type 

 district of Franconia. In Sweden all three species are known 

 from the upper part of the Rhaetic series of north-western 

 Scania, Gutbiera angustiloha occurring possibly already in the 

 zone with Lepidopteris Ottoiiis at Billesholm. The same spe- 

 cies, and also Thaumatopteris Schenki — the occurrence of which 

 at Munka Tågarp is not certain, however — extend up to the 

 Liassic of Hör. There can be no doubt that the plant-bed 

 is of Rhaetic age; and it would appear probable, from what 

 is known of the geological distribution of the species, that 

 the horizon belongs to the upper part of that formation. 

 The fact that the plant-bed occurs only 1,5 m. above the 

 Keuper would seem to speak for a lower Rhaetic age; but, 

 as has been remarked by Törnebohm & Hennig (1. c, p. 

 115), it is possible that the short distance between the plant- 

 bed and the Keuper may be due to a fault. 



2. The Flora of Rödaisberg. 



The stratigraphical position of the plant-bearing bed at 

 Rödaisberg may be seen from the section given in text-fig. 1 

 (p. 4). It is considerably higher up in the series than the 

 plant-bed at Munka Tågarp, but it lies probably a long dis- 

 tance below the Cardium-heå. The plant-bearing rock is a 

 rust-coloured, fairly fine-grained sandstone, which occurs in 

 close connection with a thin seam of poor coal. The plant- 

 remains occur as impressions, without any trace of the vege- 

 table tissue. On account of the fractured state of the rock, 

 they are very fragmentary and, moreover, not very distinct 

 as a rule. The material, which has been collected by Moberg, 

 will be described below.

In pi. 1, figs. 18 and 19. are shown two fragments which 

 are probably the remains of some equisetaceous stems. Sev-
