reticulate adj.

"reticulated, covered with netted lines, having distinct lines or veins crossing as a network," 1650s, from Latin reticulatus "having a net-like pattern," from reticulum "little net," a double diminutive of rete "net," a word of uncertain origin, perhaps related to Lithuanian rėtis "sieve," or perhaps a loan-word from a non-IE language.

"cover with intersecting lines, divide or mark in such a way as to indicate or resemble a network," 1787, a back-formation from the adjective reticulated "constructed or arranged like a net" (1728); see reticulate (adj.). Related: Reticulating.
