e th aci st SJ I the size, shape, and arrangement of the leaves, which are microphylls, small leaves with only one vein. Examine the roots and their relationship to the stem. In Selaginella, the roots grow downward from a leaf-bearing stem. The sporangia of the Lycopodiophyta are borne on leaves essentially similar to the sterile leaves of the plant. The sporangium bearing leaf is called a sporophyll. In Selaginella and Lycopodium, the sporophylls occur in compact aggregates called cones, or strobili. 1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.)
