Název v původním jazyce

Henanotheca qingyunensis sp. nov., a filicalean fern from the Lopingian of Southwest China

Popis výsledku v původním jazyce

Filicalean ferns exhibit a high degree of species diversity during the Lopingian (late Permian) epoch, although most fossil-species are preserved only as small isolated fragments of fronds, pinnules, or stems. Among these ferns, Henanotheca was recently collected from the Xuanwei Formation of Yunnan Province, Southwest China. The well-preserved sporangia and in situ spores permit the emendation of the fossil-genus Henanotheca and the establishment of a fossil-species H. qingyunensis Y.Guo, Zhou et Feng sp. nov. The new fossil-species is characterized by alternately arranged and sphenopteroid fertile pinnules with sporangial groups located at the pinnule lobes abaxially. Ovoidal to ellipsoid sporangia are irregularly grouped and bear semi-equatorial annuli. The sporangial wall has one layer of cells. Trilete spores of the Waltzispora type are described as in situ for the first time. The distinctive characteristics of sporangia and spores and the absence of vegetative anatomy would support Henanotheca being assigned to incertae sedis. Although the origin and evolution of filicaleans remain elusive, they first appeared in the Euramerican floristic region during the Carboniferous and then migrated to the Cathaysian floristic region during the Permian. Filicalean sporangia display an evolutionary trend to extant Filicales in this period.
