Rothwell and Erwin  and Bateman et al.  considered that the rootlets (or lateral appendages) produced along the shoot-like rhizomorph in the lepidodendrids are homologous with leaves on shoots and are not true roots, as in other vascular plants. However, the roots, or rootlets in their sense, of extant Isoetaceae are very similar with true roots of Lycopodiaceae and Selaginellaceae in having root caps and branching dichotomously. The proposed non-homology of the rootlets and the true roots merits further investigation.

In Equisetum, the only extant genus of the class Equisetopsida, the shoot apex has a single large apical cell [26,37]. This meristem structure seems to have long persisted, because the Carboniferous fossils, Calamites and Sphenophyllum, had similar single apical cells [64,65]. 2 Rhizophore The rhizophores of Selaginella uncinata have single apical cells, which are tetrahedral with three equal cutting faces (Fig. 2a) . The branched rhizophores of S. delicatula, S. plana, and S. caudata have also single tetrahedral apical cells .
