FIGURE 28. A–F. Spore morphology of Selaginella mairei (A–D. Megaspores, E–F. Microspores). G–L. S. decipiens (G–J. Megaspores. K–L. Microspores).—A, E, G, J, K. Proximal surfaces.—C, F, I, L. Distal surfaces.—B, D, H. Portions of surface enlarged to show infrastructural detail (B, H. Proximal surfaces; D. Distal surface). Scale bars = 100 µm (A, C, G, I & J), 50 µm (B, H), 20µm (E, F, K & L), 10µm (D).
