Origin: A borrowing from Greek, combined with English elements. Etymons: rhizo- comb. form, Greek καρπός , -ic suffix.

Etymology: < rhizo- comb. form + ancient Greek καρπός fruit (compare carpo- comb. form²) + -ic suffix. In sense 1 after French rhizocarpique ( A. P. de Candolle and J.-B. P. A. de Lamarck Flore française (1805) I. 222); compare rhizocarpous adj. at rhizo- comb. form . In sense 2 after German Rhizocarpsaüre (W. Zopf 1895, in Ann. der Chem. 284 115), itself after scientific Latin Rhizocarpon (1805).

1. Botany. = rhizocarpous adj. (a) at rhizo- comb. form . Now rare.
