438 FLORA OF THE CARBONIFEROUS PERIOD. 



which may be young Rhabdocarpi or Trigonocarpi. I have not 

 seen them attached to stems ; but their associations would lead 

 me to suppose that they may have belonged to Sigillaria or Ca- 

 lamodendron. Stems of Sigillaria of the groups Rhytidolepis and 

 Favularia bave rings of abnormal scars at intervals, which may 

 have borne such spikes of fruit. No such marks are seen on the 

 stems of other sub-genera of Sigillaria, which probably bore fruit 

 at their summits.
