Which groups include green leaf microphyllous plants?

Lycopsida sp. is a vascular plant class that includes clubmosses and ground pines. They are distinguished by the presence of microphylls. Microphylls are simple leaves with a single, unbranched vein that are found in vascular plants like Lycopsida sp. and Psilotopsida sp. They are typically small and narrow, with spirals arranged along the stem. Microphylls in Lycopsida are small, needle-like structures that give the plant a fern-like appearance.
