Taxonomic remark Assignment to order Voltziales is provisional; according to describers: Fredianthus is placed in the Voltziales— transitional between the Cordaitanthales and Pinales— though it is quite unlike any of the Laurasian male cones included in the order (pp. 57, 59). It is perhaps most readily derived from a form such as the Siberian Permian genus Cladostrobus (Rufloriaceae, Cordaitanthales, tf. 25, p. 59). In view of the lack of any established affiliation with ovulate cones or foliage, Fredianthus is not included in any formal family. However, considering its unique size and arrangement of microsporangia, it probably represents a new group at this rank. [details]
