Taxonomic remark From Foraponova & Karasev, 2021: The genus Permotheca is a heterogeneous genus and is comprised of species which are, probably, not related to each other ... The [type] species P. sardykensis is significantly different from other Permotheca species in that it is represented by sporangia sitting on a branched sporangiophore, whereas other Permotheca species are represented by synangia ... Associations of species P. sardykensis, P. deodara, P. fimbriata, and P.? musaformis sp. nov. with other dispersed organs of fossil plants are currently unknown. From other sources: Wachtler, 2020 considers Permotheca colovratica an early angiosperm, which is unlikely considering its claimed age (Early Permian). [details]
