   Tundra \Tun"dra\ (t[=oo]n"dr[.a]), n. [Russ.]
      One of the level or undulating treeless plains characteristic
      of northern arctic regions in both hemispheres; the term is
      most commony associated with the arctic plains of Siberia.
      The tundras mark the limit of arborescent vegetation; they
      consist of black mucky soil with a permanently frozen
      subsoil, but support a dense growth of mosses and lichens,
      and dwarf herbs and shrubs, often showy-flowered.
