coriander (n.)

popular name of an umbelliferous plant (Coriandrum sativum) with a seed-like aromatic fruit, late 14c., coriaundre, from Old French coriandre (14c.), from Latin coriandrum, from Greek koriannon, often said by botanists to be related to koris "bedbug" from the bad smell of the unripe fruit, or perhaps it is a non-Indo-European word conformed to the Greek insect name.
