Zamuneria amyla L.C.A.Martínez, A.Iglesias et Artabe in Martínez, Iglesias, Artabe, Varela & Apesteguía
Columnar, polyxylic stem, covered by persistent rhomboidal leaf bases and cataphylls. Parenchymatous central pith with mucilage canals, idioblasts and medullary vascular bundles. Cylindrical vascular system centrifugal, with many rings of manoxylic secondary xylem and phloem, containing primary and secondary rays. Primary rays with leaf traces and a mucilage canal associated. Parenchymatous cortex with mucilage canals, idioblasts and girdling leaf traces in the cortex.
The genus honours the late Dr. Alba B. Zamuner, an Argentinian palaeobotanist who passed away in 2012, and who made signiﬁcant contributions to our knowledge of fossil ﬂoras from Argentina. She was one of the leaders of the expedition in which this fossil was discovered.
