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).
