FIGURE 11. A–F. Spore morphology of Selaginella monospora var. ciliolata (A–D. Megaspores, E–F. Microspores). G–L. S. monospora (G–J. Megaspores, K–L. Microspores).—E, K. Proximal surfaces.—C, F, H, L. Distal surfaces.—A, G. Lateral surfaces.—B, D, I, J. Portions of surfaces enlarged to show infrastructural detail (B. Proximal surface; D, I, J. Distal surfaces).
