scribed somewhat similar stems with zones of different kinds 

 of scars. A determination of the present fragments or any- 

 closer comparison with other known forms is clearly im- 

 possible. 



Desmiopljylliim sp. 



PI. 6, figs. 1—3. 



The fragments shown in pi. 6, figs. 1 — 3, are best men- 

 tioned under the provisional name Desmiophyllum. 



The specimens represent portions of linear leaves, or 

 segments of compound ones, reaching a length of 3 — 4 cm, 

 with a breadth of up to 7 mm. The specimen in fig. 1 is 

 distinctly tapered towards the base, the one in fig. 2 has 

 almost parallel edges. Both .specimens have simple, parallel 

 veins, 8 — 12 in number. In the specimen in fig. 2, there can 

 be seen a much finer interstitial vein between each two of 

 the stronger ones (fig. 3). There is some difference between 

 the specimens. The one in fig. 1 has denser veins and shows 

 no interstitial veins, though it may well possess such. The 

 occurrence of intermediate specimens, however, renders the 

 identity probable. 



It is impossible to state the exact nature of these fragments. 

 They may represent portions of simple, tape-like leaves and may 

 in that case belong to Phoenicopsis Heer.^ Of Heer's species 

 two are stated to have a fine interstitial vein between each 

 two of the stronger ones, viz. Ph. speciosa (Heer, 1. c; pi. 29, 

 figs. 1, 2; pi. 30) and Ph. latior (ibid.; pi. 31, figs. 1—6; pl.29, 

 fig. 1 c). It is possible, however, that the specimens repre- 

 sent segments of leaves of a Baiera, of which genus some 

 species are described as having similar interstitial veins (Heer, 

 1. c). The best course is, under these circumstances, to use 

 the non-committal name Desmiophyllum, which does not ex- 

 press any opinion regarding the affinities.
