Lepidodendron is an extinct genus of primitive (tree-like) plant. They were the first large land plants, and a major part of the coal forest tropical flora. They were huge, over 30 metres (100 feet), and the trunks were often over 1 m (3.3 ft) in diameter.Sometimes called 'giant club mosses', they are actually closer to the quillworts Isoetes than to clubmosses.hey were the first large land plants, and a major part of the coal forest tropical flora.
