The "scum" is actually a couple of really neat aroids. The tiny (actually
the smallest flowering plant) Wolffia can be identified along with the larger
Lemna by checking into Landolt's Lemnaceae, Fl. North America 22: 143-153.
Oxford University Press (2000).

Lemna is no longer in the Araceae. It belongs to

I am afraid you are dead
wrong, it is just the other way around!! All Lemnaceae are now Araceae, unless
something changed no later than a month ago.

Dear Marek,

I don?t know if something changed in the last five minutes, but
unless all phylogenetic methods are wrong, the "Lemnaceae" are much more
deeply embedded within the Araceae than Anthurium! If Lemnaceae as so is a
accepted family, you have to take Anthurium, Spathiphyllum and Monstera out
of the Araceae. For those that have been "out of the business" for the last
years, many families have disappeared (e.g. Asclepiadaceae is now in
Apocynaceae; Bombacaceae is now in Malvaceae; Taccaceae is now in
Dioscoreaceae). Other are almost there, such as Amaryllidaceae (to be
swallowed by the Alliaceae). Sad but true...

Best wishes,
