Review of Palaeobotany and Palynology, 2012
A distinctive fungal endophyte, Cashhickia acuminata nov. gen. et sp., is described from permineralized calamite roots from the Upper Pennsylvanian Grand-Croix cherts of France. Heavily infected roots contain numerous intracellular hyphae in the outer cortex that arise from a meshwork-like mycelium extending between cortical cells.

A new Carboniferous equisetale from western Gondwana
Geobios, 2006Upper Paleozoic sphenopsids from western Gondwana are little known. New finds were made from the Upper Carboniferous of the San Juan province (Argentina). The specimens include vegetative and fertile characters that allow the definition of a new genus and species: Gondwanites subtilis.

An Upper Pliocene Equisetum (Equisetales) from the Atotonilco El Grande Formation in Central Mexico
Paleontological Journal, 2009The present work documents the occurrence of Equisetum in the Upper Pliocene deposits of Central Mexico, describing and comparing fossil taxa with modern specimens. All taxonomic characters suggest a close affinity to the modern species Equisetum myriochaetum Schldl. et Cham.

Three types of anatomically preserved vegetative shoots with features that characterize crown group Equisetum have been discovered in Lower Cretaceous deposits (≈136 Ma) of British Columbia, Canada, suggesting the genus is much older than currently believed. Specimens include two types of aerial shoots described as E. haukeanum sp. nov.

Canadian Journal of Botany, 1986
Vascular cambium activity was examined in Arthropitys communis (Binney) Hirmer et Knoell, and A. deltoides Cichan et Taylor, anatomically preserved calamite stems from the Pennsylvanian of Kentucky. Developmental characteristics of the meristem were inferred from changes in the size and number of tracheids and ray cells determined from serial ...

INTRODUCTION The recent finding by Mr. J. T. Woods of beautifully preserved though fragmentary remains of fertile fronds of a species of Equisetites at Brighton, near Sandgate, is of importance from several aspects. Such fertile remains are not common anywhere in the world, and it is rare indeed that one finds material such as this from which the ...
