Cryptocoryne nurii Furtado "Pijoan"

This species popped up together with C. species "Pelan" around 2005 in Japan from where it was distributed all over the world. It is said that it was collected in Pijoan, Jambi province, Sumatera. It was never recollected as far as I know. The plant resembles the broad leaved nurii's from the Riau Archipellago province of Sumatera and in Pahang in the Malay peninsula, but has a typical twisted limb of the spathe. The pollen fertilty is zero (0) therefore is it suspected to be of hybrid origin.

There are reports from Japan that the colour of the limb also can be bright yellow with small red dots. This is a well known phenomen when red dots 'grow' and the yellow base may even disappear. It is also known for example in C. minima.
