  > Yukimarimo were named by T. Kameda on JARE-36 in 1995. "Yuki" means snow in Japanese, and "marimo" is a ball-like growth of water algae which the yukimarimo resemble. [1] > The plant was named marimo by the Japanese botanist Takiya Kawakami[b] in 1898. Mari is a bouncy play ball. Mo is a generic term for plants that grow in water. The native names in Ainu are torasampe (lake goblin) and tokarip (lake roller). [2] The roller comes full circle!

    Nice find! I thought I had done a blog post with the reference to "snow down" (the same phenomenon later named yukimarimo) in Paul Siple's account of the first South Pole winter over in 1957, but apparently wrote that up for something else... Perhaps a bit of wikipedia editing is on the menu for this weekend!
