REVISION OF COMPTONIA 



507 



This is a beautiful species with large leaves some fifteen centi- 

 meters in length and upwards of three centimeters in width, irregu- 

 larly lobed; each lobe with one or more serrations of the margin 

 besides the rather larger, somewhat falcate, usually pointed tip. 

 There is considerable variation in the depth of the sinuses, Unger's 

 type figure from Sotzka showing a leaf witli deep sharp sinuses, 

 while the handsome specimen figured' by Heer [loc. cit.. PI. 70, 

 Fig. 7) has more shallow and slightly rounded sinu.es. The sharp- 

 in the basal and apical portions of the leaves, in fact one of the 

 leaves figured l)y Ileer has them distinctly rounded. 



As remarked under r'o////;/o///rt rindoboneusis, some of the leaves 

 of that s[)ecies are <niite close to this one and are also represented 

 by variati(ms of the modern leaf, an example of which is figured 

 on Pi. 2. Fig. :.. The hitter, while shorter and not exactly similar to 

 lociiildfa, has precisely the same character of serrated lobe^.
