Lepidodendron – also known as the scale trees – is an extinct genus of primitive, vascular, tree-like plants related to the isoetes and lycopsids (club mosses).They were part of the coal forest flora. They sometimes reached heights of over 30 metres ( ft), and the trunks were often over 1 Clade: Tracheophytes.

In this, the strobilus had a central axis bearing whorls of sporangiophores. Alternating with the whorls of sporangiophores were whorls of sterile appendages called bracts. The sporangiophores had cruciately branched apices. The tip of each branch recurved towards the strobilar axis and had a sporangium at the tip.
modifications of the primary type-one from the Lower Coal-measures of Oldham in Lancashire, the other from those of Burntisland. In its youngest state, the Oldham form first appears as a mere twig, having a central fibro-vascular bundle enclosed in a double bark.

As a rule the casts of Calamite stems are pith- casts, which are formed by the filling up of the hollow pith cavity by mud or sand, which, when set hard, gives us a shale or sandstone cast. The next three photographs show such pith-casts. The pith cast of Calamites is the most common plant steinkern.
As a Calamites tree matured the center of the stem (pith) became hollow, developing into a tube-shaped air cavity.
The pith cast preserves an impression of the pith cavities outside surface, which represents the inside vascular and cortex tissue (Taylor, Taylor & Kring,p. 23). This new ‘Mostra’ will form part of the International Exhibition of the year — the ‘E.
