<i>Paradiospyroxylon kvacekii</i> gen. et sp. nov. from the Paleogene of the Czech Republic: a case study of individual variability and its significance for fossil wood systematics

The wood anatomy of <i>Paradiospyroxylon kvacekii</i> gen. et sp. nov. is described and illustrated based on material originating from the Ústí Formation’s volcanic deposits of České středohoří Mts. (Paleogene, Czech Republic). The sample, identified earlier as <i>Manilkaroxylon</i> sp., was critically examined and is interpreted as root wood and proposed as the paratype of <i>Paradiospyroxylon kvacekii</i>. This paper discusses how wood anatomical variation needs to be considered when making systematic and palaeoecological interpretations.
