indiscrete (adj.)

"not containing distinct parts," 1782 (earlier "not distinctly separate," c. 1600), from Latin indiscretus "unseparated; indistinguishable, not known apart," from in- "not, opposite of" (see in- (1)) + discretus "separated, distinct" (in Medieval Latin "discerning, careful"), past participle of discernere "distinguish" (see discern).
