Word History


borrowed from New Latin, genus name, probably borrowed from Greek polýporos "with many passages," from poly- poly- + -poros, adjective derivative of póros "pathway, passage through the skin, pore entry 2"

Note: The genus name was assigned by the French botanist Michel Adanson (1727-1806) in Famille des plantes, deuxieme partie (Paris, 1763), p. 10, following pre-Linnaean introduction by the Italian botanist Pier Antonio Micheli (1679-1737) in Nova plantarum genera (Florence, 1729), pp. 129-31, tabula 70. According to Micheli, "Polyporus dicitur a multis poris, vel a copia multorum foraminulorum, quibus inferiori pilei parte densissime est cribratus" ("The polypore is so called from the many pores, or profusion of small openings, with which the under part of the cap is densely sifted").
