■fig. 3. 



A few fragments of tlie carbonized cortex of this species were found 

 among- the fragments of black laminated "bone" from Jordan's coal mine. 

 The leaf scars, which are very close vertically, are separated horizontally 

 by a faintly flexuose, lineate fuiTOw, so that our specimens very closely 

 resemble, both in size and in aspect, the enlargements of Sigillaria ciimulata 

 \?a: paucistriata given by Weiss ^ in his elaboration of the Favularice. The 

 form in hand probably represents the variety y of Brongniart. 



Although Sigillaria tessellata is kept separate from S. elegans Brongn. by
