Surprised that I hadn't encountered the word before, I had to consult my OED, which cites usages dating back to the early 19th century. The etymology is from a Greek word meaning wooded pasture or glade. There is also adjectives nemorivagant ("wandering in woods") and nemorose ("full of woods") and nemorous ("woody" - dating to 1623).
