BAIERA. 



convenient designation ; the original name /areata of Lindley & 

 Hutton was adopted in 1843 by Brann, who called the plant Baiera 

 /areata, but in 1865 Hccr named some fragments of leaves from 

 Keuper beds of Switzerland Scleroph ijllma /areata, and afterwards 

 substituted the generic name Baiera, possibly in ignorance of the 

 use of the same name by Braun in 1843. 



Baiera Lindley ana may be compared with B. spetsbergensis, Xatb., 1 

 from the Upper Jurassic of Advent Bay, also with B. tenuifolia, 

 Johnst., 2 from the Jerusalem Coal-basin of Tasmania.

Similar in form to Baiera gracilis, except in the narrower and 

 more frequently branched segments. The tips of the segments 

 tire obtusely pointed as in B. gracilis. The Leckenby Collection, 

 Cambridge, contains some specimens of B. Lindleyana in which the 

 narrow segments are more widely spread, giving the leaf a broader 

 form similar to that of B. gracilis, as shown in PL IX. Fig. 3.
