Lepidodendron species were comparable in size to modern trees. The plants had tapering trunks as wide as 2 m (6.6 ft) at their base that rose to about 40 m (130 ft) [ 2 ] and even 50 m (160 ft), [ 1 ] arising from an underground system of horizontally spreading branches that were covered with many rootlets.
Various specimens of Lepidodendrales have been historically categorized as members of Lepidodendron, a genus defined by morphology of leaf cushions. DiMichele established Diaphorodendron to dissuade ambiguity over these widely ranging specimens, which includes some structurally preserved specimens which were previously members of Lepidodendron.
The Carboniferous lycophytes of the order Lepidodendrales, which were cousins (but not ancestors) of the tiny club-mosses of today, were huge trees with trunks 30 meters high and up to 1.5 meters in diameter. These included Lepidodendron (with its fruit cone called Lepidostrobus), Halonia, Lepidophloios and Sigillaria.
