  According to Arber, Lemna species form turions, which in the case of
Lemna are leaves densely packed with starch that fall to the bottom of the
pond or lake.  In the spring, these rise, presumably due to gases produced
by photosynthesis, and expand into typical Lemna leaves.
  I haven't seen these for Lemna, but I have seen the turions of
Utricularia and Myriophyllum.
