nov. are both sprouting from a common stem, and consequently improve our understanding of the whole plant morphology of this enigmatic taxon of the Cathaysian flora. The strobili are cylinder-like, 1.7–2.5 cm in diameter and over 20 cm in length, with a basal stalk 7–8 mm in width and about 7 cm long. Sporophylls are verticillate, with approximately 8–10 in a whorl. On the adaxial side of each sporophyll a sporangium is attached. The strobilus is heterosporous and the microspores are of the Punctatisporites type. Large leaves vary from linear to oblong with entire lateral margins but are slightly lobed at the apex. Small leaves are generally the same as the large leaves but much narrower. The whole plant is probably a small arborescent tree with leafy shoots and strobili forming a crown, rather than a water plant with larger leaves floating on the surface of the water as previously understood. Features of the new species are in favor of the close affinity between Tingia Halle and Noeggerathiales, and accordingly the affinity of Noeggerathiales to Progymnospermophyta.
