  • Stratigraphic and geographic range (Stratigrafické a geografické rozšíření):  Bashkirian Europe and Canada. CZ: Svrchní Namur (Yeaedonian) až Vestfál A (Langsettian) Hornoslezská pánev, Vestfál B (Duckmantian) Skotsko, Vestfál A (Langsettian) až Vestfál C (Bolsovian) Velká Británie, svrchní část Vestfálu A (Langsettianu) až spodní část Vestfálu C (Bolsovianu) Španělsko, Vestfál A (Langsettian) až Vestfál C (Bolsovian) Kanada.
  • Remarks (Poznámky):  První publikované nálezy taxonu Flemingites russelianus (Binney 1871) Brack-Hannes & Thomas 1983 z hornoslezské pánve. Šištice jsou nalézány společně s větvemi druhu Bergeria dilatata (Lindley & Hutton 1831) Álvarez-Vazquez & Warner 2014. Tak je tomu také v hornoslezské pánvi, na lokalitě Karviná - Důl ČSA. Je tedy nepochybné, že se jedná o fosilní zbytky jediného taxonu.

117 DESCRIPTION. Cylindrical strobilus up to 60 mm long and 15 mm broad, tapering only in the top part to end in a rounded apex. Sporophylls arranged in a low-angle spiral, rigid in aspect and closely adpressed. Sporophyll lamina lanceolate, with acute apex and a relatively broad, prominent central vein. Dimensions: up to 10 mm long and 1.3 mm wide.

118 REMARKS. The association of Flemingites russelianus with Lepidodendron acutum (now Bergeria dilatata) has been generally recognized (e.g., Chaloner 1953; Álvarez- Vázquez 1995). All the Canadian specimens included in this species are associated with branches of Bergeria dilatata. None of these display sporangial contents.

The incomplete strobilus figured by Jongmans (1937, pl. 15, fig. 25) as Lepidostrobus cf. goodei, most likely belongs to Flemingites russelianus, a conclusion reinforced by its association with Bergeria dilatata (recorded by Jongmans as Lepidodendron ophiurus).

119 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION. Binney’s material comes from Airdrie, Lanarkshire, Scotland, from rocks of Duckmantian age. Chaloner (1953) and Crookall (1966) recorded the species from Langsettian to Bolsovian in Great Britain. In the Peñarroya Basin, southwestern Spain, it occurs in upper Langsettian and upper Duckmantian/lower Bolsovian strata (Álvarez-Vázquez 1995, 2000), often in association with specimens of the relatively common Bergeria dilatata.

120 OCCURRENCE IN THE MARITIME PROVINCES, CANADA. Cumberland Basin (Nova Scotia): locality 1053 (GSC 9951 — fragmentary + GSC 9952 + GSC 9953 — together with Senftenbergia plumosa); locality 1406 (GSC 9913 — strobili associated with leafy branches of Bergeria dilatata + one specimen without catalogue number); locality 1411 (two pieces — together with leafy branches of Bergeria dilatata); locality 1496 (one specimen, part and counterpart, associated with Bergeria dilatata, Calamites suckowii and Dorycordaites palmaeformis).

121 OCCURRENCE IN THE UNITED STATES. Michigan: Arnold (1949).
