Taxonomic remark From Philippe & Bamford, 2008: An intricate case, this genus has two syntypes (Conwentz, 1885). Andrews (1955) did the first lectotypification but at the same time elected the same species as lectotype for Circoporoxylon Kräusel (an error he repeated in 1970, deliberately ignoring the lectotypification of Circoporoxylon by Kräusel and Jain in 1964). Andrew's choice, based on an automatic method (first species cited) may be superseded (ICBN, art. 8). The fact that Kräusel (1949) removed one of the syntypes from Glyptostroboxylon can no longer be considered an act of lectotypification (formerly socalled ‘residue lectotypification’, ICBN, Art. 7.11). Thus the Glyptostroboxylon type species was considered for long as non-designatus (ING), until Süß and Velitzelos in 1997 designated G. tenerum (Kraus) Conwentz. This generic name was used for the Mesozoic only by Natschokin (G. senomanicum, later transferred to Protoglyptostroboxylon by He Dechang in 1995), and woods from the Kimmeridgian of Tanzania (Kahlert et al., 1999; Süß and Schultka, 2001, 2006) with araucarian cross-fields (i.e. with numerous contiguous alternate oculipores). The presence of Glypstroboxylon has not yet been demonstrated for the Mesozoic. [details]
