In botany, describing a type of leaf venation in which the vein reaches to the leaf margin or edge.
From Greek kraspedon (margin, edge) plus dromos (running course), combining botanical terminology. This describes the pattern where leaf veins 'run' all the way to the edge rather than stopping short.
Botanists have incredibly specific vocabulary for how leaves are veined—'craspedodromous' tells you the vein pattern literally runs to the edge. It's like they have a different word for every architectural design nature comes up with in leaves.
