Adelia is a genus of flowering plants in the spurge family, Euphorbiaceae, subfamily Acalyphoideae.

[1] It is native to Latin America and the Caribbean, with one species extending northward into the southernmost part of Texas.

[2][3][4][5][6][7] The name is derived from the Greek words α (a), meaning "not", and δήλος (delos), meaning "visible."

It refers to the difficulties Linnaeus experienced interpreting the genus.
