Answer:
club mosses
Explanation:
Microphyll is a type of plant leaf defined by the existence of a single non-branching rib. The present species that have microphiles have small and relatively simple leaves, associated with protosteal stems; however in the past there were representatives with microphiles up to one meter long. The most widely accepted theory about the origin of microfiles is that they evolved from lateral projections of the main axis.
Microphils are characteristic of club mosses, spike mosses, and quillworts leaves.
