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).
