MAS ^ has recently studied the fructifications of Engh'sh speci- 

 mens and referred the species to a new genus, Eboracia, 

 considered to be allied to the Cyatheaceae. 



Cladophlebis lohijolia is typically an Oolitic species, and 

 is known from Middle Jurassic rocks in several districts. In 

 Tonkin it appears to occur already in the Rhaetic, and it is 

 also a characteristic member of the Bagaa-flora of Bornholm, 

 which is considered to be Liassic and shows agreement both 

 with Rhaetic and Middle Jurassic floras. It has not hitherto 

 been recorded from Sweden. 



Gutbiera aiigustiloba Presl.

 ridofyter. Lunds Univ. Årsskr. Bd 38. Afd. 2. N:o 5. 1902. P. 35; 

 and The flora of Munka Tågarp in the present paper, p. 8.] 



A very small fragment, measuring only about 3 mm. in 

 length, probably belongs to this species. In spite of the 

 small size, the identification is fairly certain because of the 

 characteristic areas shown by the fragment, of which both 

 counterparts are preserved. For further reference, see above 

 p. 8. 



Laccopteris sp. 



PI. 2, figs. 9, 10. 



A few fragments of fern-pinnules, two of which show 

 traces of small and indistinct sori, may be mentioned under 

 the generic name Laccopteris. The best specimen, which is 

 sterile, is figured in pi. 2, figs. 9 and 10. As is shown by 

 the enlarged drawing in fig. 10, the venation anastomoses, 

 close to the midrib, to rather small meshes. These are not 

 always distinguishable, however. Taking into account the 

 place of the sori, and since Seward ^ has shown that Lacco- 

 pteris has anastomosing venation, it appears permissible to 

 refer the present fragments to that genus, but a specific 

 determination is naturally impossible.
