Dots and Dashes.
Detail of a leaf of Agave americana 'variegata'. IHNC what caused the wounds to the leaf.
If you look closely you'll see that the cream colored outer stripe is smooth, while the green part is softly mottled. The entire leaf is extremely stiff and pretty hard.

As with most plants, amazing details are revealed when you look closely. I hope you'll take the time to view at least some of these images in their larger sizes, or download them and view them with "zoomable" viewing software. Above all, enjoy!
