FIGURE 4. Cross-sections of cypselae of Mexican Mutisieae. A–E. Adenocaulon lyratum A. Whole cypsela. B–C. Detail of glands. D. Epicarp with flattened square cells. E. Mesocarp with vascular bundle. F–I. Gerbera hintonii. F. Whole cypsela. G. Epicarp and mesocarp. H. Thick-walled cells of the inner mesocarp and endocarp. I. Crystals (arrows) in endocarp cells. J–M. Leibnitzia lyrata. J. Whole cypsela. K. Epicarp with hemispherical cells. L. Mesocarp with vascular bundle. M. Thick–walled cells of the inner mesocarp and endocarp. e = epicarp, m = mesocarp, n = endocarp, s = sclereids, * = vascular bundle. Scale is 300 µm in A; 100 µm in B, F, J; 50 µm in C, E; 20 µm in G; 10 µm in D; 5 µm in H, I, K–M.
