Answer:Club mosses are low evergreen herbs with needlelike or scalelike leaves. Many species have conelike clusters of small leaves (strobili), each with a kidney-shaped spore capsule at its base. The plants are homosporous, meaning they produce just one kind of spore

Explanation:Although they lack true veins, many species of mosses have long narrow cells in their stems, the midribs of their leaves, and their rhizoids (root-like plant tissue) that can be considered evolutionary precursors to true veins. Vascular plants with true veins include the clubmosses, ferns, and flowering plants.
