Like the woven cords in a fisherman’s net, “reticulation” refers to netlike formations produced by interconnected lines. “Reticulation” stems from a Latin word meaning “small net.” However, today, the word is commonly used when describing the patterns on leaves. It also has a specific usage in photography — when chemicals are used to develop film photography, a network of cracks can appear during the emulsion process, and these cracks are called “reticulation.”
