| Abstract: | Leisman , Gilbert A. (Kansas State Teachers Coll., Emporia.) The morphology and anatomy of Callipteridium Sullivanti. Amer. Jour. Bot. 47(4) : 281—287. Illus. 1960.–Previously undescribed pinnules of Callipteridium Sullivanti (Lesq.) Weiss have been studied in Iowa and Kansas coal balls. Conventional peel techniques revealed the anatomy while deliberately fracturing the coal ball revealed morphological features. Epidermal studies were also conducted after macerating small portions of the coal ball. Evidence indicates that these pinnules were borne on Myeloxylon petioles. Arguments are advanced for removing this species from the genus Alethopteris and returning it to Callipteridium. |
