Origin: A borrowing from Latin. Etymon: Latin Polystichum.

Etymology: < scientific Latin Polystichum, genus name ( A. W. Roth Tentamen florae germanicae (1799) III. 31) < Hellenistic Greek πολύστιχος in many rows ( < ancient Greek πολυ- poly- comb. form + στίχος row, line: see stich n.), so called on account of the arrangement of the sori in rows on the underside of the leaflets in many species. Compare earlier scientific Latin polystichum, epithet of a kind of barley (1727).
