noun mountain avens
originBorrowed from translingual Dryas for the plants, from both Latin Dryas and Ancient Greek Δρῠᾰ́ς (Drŭắs), derived from δρῦς (drûs, “tree, oak”). The second definition comes from the large quantity of pollen from the plant that is found in ice cores dating from these periods.
