Back in October of 09, a friend of mine, Kai Terukuni, went collecting in Lingga island in Indonesia. Among some of the crypts he found and collected was one he labelled Cryptocoryne sp. Desa Musai Timur, Pulau LINGGA[LNG-7].
A few pictures of the habitat by Kai.
Additionally, here’s a link to some video of the habitat.
A fairly shaded shallow stream with a sandy bottom.
This plant flowered around the end of December 09 and then again in early January.
Cryptocoryne scurrilis? I’ll send the pictures to Jan to be identified.
