Examination of Iowa coal balls from the Des Moines Series has yielded two petrified stern fragments assignable to the arborescent lycopod genus Lepidophloios. Details of the leaf cushions and internal stem anatomy are described and compared with similar specimens from Kansas and Illinois coal balls. In light of these observations, criteria presently used to distinguish among species of Lepidophloios are re-examined. In particular, the diagnostic features of Lepidophloios kansanus (Felix) Eggert and L. pachydermatikos Andrews & Murdy are reviewed and determine to represent ontogenetic differences. The probable conspecific nature of the above taxa results in assignment of the Iowa specimens to L.kansanus sensu lat.
