“…The taxon would thus be clearly different from S. miravallis. Kerp (1981Kerp ( , 1984, emphasizing among other characters the relative thinness of the lateral veins, considers Sterzel's specimens to belong to Lilpopia raciborskii (Lilpop) Conert et Schaarschmidt, which shows this feature as well. In our opinion the specimen figured by Wagner and Artieda (1970) under the name S. thonii var.…”

This paper deals with a detailed study of Sphenophyllum miravallis Vetter, a member of the "Sphenophyllum thonii group". New material from the Reisbach colliery, working the "]]linger F15zzone" of the "Heusweiler Schichten" (Lower Stephanian, Saar Basin, German Federal Republic), is described morphologically and anatomically, and the species is discussed. The new material enlarges the known range of variability of the normal aspect of the foliage, i.e. the foliage of the thinner branches. Thicker stems with their aberrant polymorphous foliage, and cellular details, are described for the first time. An emended diagnosis is given. Comparisons with other species are made.

“…Given the intraspecific variation in Sphenophyllum leaves, identifying isolated leaves often must be tentative. Possibilities include Sphenophyllum verticillatum and Lilpopia raciborskii (see comparisons in Kerp, 1984;Wagner, 1985;Barthel, 2009).…”

“…Tristachya ) is a sphenophyllalean taxon (Taylor & Taylor, 1993: 315). Although this plant possesses sporangia below a leaf [ sensu the reconstruction presented by Kerp (1984)], it differs from Rotafolia in that the fertile region is situated between the upper and lower vegetative leaves, the sporophylls lack distal or lateral divisions and the tiny ovoid sporangia are arranged in clusters.…”

A sphenopsid from the Upper Devonian (Famennian) Xiejingsi Formation, south-western Hubei Province, China, previously named as various species in Sphenophyllum , Hamatophyton , Bowmanites and Sphenophyllostachys , is now reinvestigated and assigned to a new taxon, Rotafolia songziensis gen. et comb. nov. Its ribbed axes are anisotomous and possess slightly expanded nodes. Lateral axes are inserted at nodes on main axes. Whorls of much divided vegetative leaves are attached at nearly right angles to nodes of basal axes, and at acute angles to nodes of terminal axes. There are six leaves per whorl. The terminal strobilus includes a central axis and verticils of fertile units. Each fertile unit consists of a bract and numerous sporangia. The margin of the elongate-cuneate bract bears a distal and many lateral elongate segments. Clusters of elongate sporangia are abaxially attached to the base of the bract at the same level. The axis has an actinostele, composed of a three-ribbed, exarch primary xylem and radial secondary xylem. Although Rotafolia songziensis closely resembles Hamatophyton verticillatum in axis character, leaf morphology and primary xylem type, they are quite different in strobilar structure. Taxonomically, Rotafolia is placed in the order Sphenophyllales by three well-defined characters: 1) whorled appendages; 2) ribbed protosteles; 3) exarch primary xylem maturation.
