    Rarer lycopod fossil ,
    interesting
    fossil young branch of
    Lepidophloios larcinus
    Sternberg
    1820
    called
    Halonia tortuosa
    Lidney & Hutton
    The genus
    Lepidophloios
    appears to have been established by Sternberg at a time when our knowledge of Carboniferous plants was based, for the most part, upon merely superficial characters and not upon the anatomical structure of the plants themselves. The two genera, Lepidodendron and Lepidophloios, though long known to hold close affinities, are clearly separated by well-marked characters.  In Lepidophloios the leaf-cushions are rhomboidal (as in L. laricinum) or elongated-truncate (as in L. scoticum), and the leaf-scar is situated at the extremity of the cushion, having three punctiform cicatricules as in Lepidodendron. The cones are borne on specially modified branches and are arranged in spirals (Halonia). These young branches grew for the propagation period from the main trunk with cone on top. After reaching maturity by the cones, twigs with the cones  fall off on the ground.
