“…Remarks-These specimens from New Mexico and Texas (USA) were originally identified as A. carinata and have similar anisophyllous leaf whorls (DiMichele et al, 2010(DiMichele et al, , 2013(DiMichele et al, , 2021Xu et al, 2018). However, they differ from both A. carinata and A. spinulosa in having more bulbously oblanceolate leaves with an obtuse apex.…”

Seven fossil–species can be distinguished within the range of late Carboniferous and early Permian equisetopsid (“horsetail”) foliage formerly assigned to Annularia stellata. The shoots bearing this foliage also produced distinctive strobili often known as Calamostachys tuberculata. These foliage species can be differentiated by leaf and whorl morphology, and each species has a distinct geographical and stratigraphical range. The group first appeared in the intramontane basins of the Variscan Mountains in the late Duckmantian, and then expanded into the lowland paralic coal swamps in the Bolsovian–Asturian. The group continued to flourish in coal swamp refugia during the Stephanian but eventually disappeared during the early Permian.

“…The latter species is very rare and in many European Rotliegend basins even absent. However, it has recently been recognized in the southwestern United States, where it can be locally abundant in the upper Pennsylvanian and may occur as low as the middle Pennsylvanian (Lucas et al, 2013;DiMichele et al, 2013DiMichele et al, , 2017. In addition, two species were recorded from the Collio Formation (Artinskian) in Val Trompia, northern Italy, i.e.…”
