Dammarophyllum VELENOVSKÝ ex J. KVAČEK, 2003
T y p e: Podozamites striatus VELENOVSKÝ, 1885b, p. 10 , pl. 2, fig. 8. = Dammarophyllum striatum VELENOVSKÝ ex J. KVAČEK, 2003, p. 14 , fig. 1a.
D i s c u s s i o n. The generic name Dammarophyllum was first published by Velenovský (1889) in combination Dammarophyllum striatum (VELENOVSKÝ) VELENOVSKÝ nom. nud. without any diagnosis or description, so it was invalidly published. However it was commonly used in further publications ( Frič and Bayer 1901, 1903, Seward 1919, Hluštík 1980). The genus was later validated by J. Kvaček (2003).
The difference between genera Dammarophyllum , Podozamites C. F. W. BRAUN and Lindleycladus HARRIS is based on the epidermal leaf structure (see J. Kvaček 2003). Dammarites PRESL has, in contatrast to Dammarophyllum , long linear leaves without any petiole. It differs remarkably in having stems short and cone-shaped ( Hluštík 1976). The genus Nageiopsis FONTAINE shows venation ending in leaf margin, and does not convert to the apex, which is typical for the genus Dammarophyllum . From all mentioned genera, the genus Dammarophyllum differs in venation pattern: between wider veins there are typically present intersecondary veins (J. Kvaček 2003).
