Professor Penhallow[190] instituted this name for a specimen measuring 8 cm. long by 6 mm. in breadth, collected by Mr Reid from the Old Red Sandstone of Caithness, consisting of an axis bearing narrow lanceolate leaves some of which bear sporangia at the base. _Lycopodites Gutbieri_ Goeppert[191]. 1894, _Lycopodites elongatus_ Kidston[192] (not Goldenberg). The species, figured by Geinitz as _Lycopodites Gutbieri_[193], from the Coal-Measures of Saxony is probably a true representative of the genus. The Saxon specimens are heterophyllous; the larger lanceolate and slightly falcate leaves arranged in two rows, are 4–5 mm. long while the smaller leaves are one half or one third this size; some of the dichotomously branched shoots terminate in long and narrow strobili not unlike those of Zeiller’s species _Selaginellites Suissei_[194]. Kidston[195] has included under this specific name some fragments collected by Hemingway from the Upper Coal-Measures of Radstock, Somersetshire, but as only one form of leaf is seen the reasons for adopting Goeppert’s designation are perhaps hardly adequate. _Lycopodites ciliatus_ Kidston[196]. Under this name Kidston describes a small specimen, obtained by Hemingway from the Middle Coal-Measures of Barnsley in Yorkshire, consisting of a slender forked axis bearing oval-acuminate leaves approximately 5 mm. long with a finely ciliate margin. Associated with the leaves were found spores which Kidston regards as megaspores. _Lycopodites macrophyllus_ Goldenberg[197]. This species, originally described by Goldenberg from the Coal-Measures of Saarbrücken has been re-examined by Halle[198] who is unable to confirm Goldenberg’s statement as to heterophylly. The shoots closely resemble _Selaginellites primaevus_[199] (Gold). [Illustration: FIG. 135. _Selaginellites and Lycopodites._ (After Halle.) A. _Selaginellites primaevus_ (Gold.). × 10. B.

Halle has founded this species on specimens, from the Coal-Measures of Zwickau in Saxony, characterised by dimorphic lanceolate leaves in four rows, the larger being 4–6 mm. long: the smaller leaves have a ciliate edge. A comparison is made with the recent species _Selaginella arabica_ Baker, _S. revoluta_ Bak., and _S. armata_ Bak. in which the leaves are described as ciliate. In the absence of sporangia and spores the species is placed in the genus _Lycopodites_. _Lycopodites lanceolatus_ (Brodie). Fig. 136.
