Schismatoglottis Roseospatha

It isn't a Bucephalandra species, but it also belongs to the Araceae family. It also has shining dots and able to attach to the rocks.

It's named for the spathe colour, which in the original collection was rose pink. Wild populations range from rose pink to almost white. In habitat it grows in full sun on water-splashed rocks (P. Boyce).

It's a quite small specimen - it has about 10-12 cm height. Submersed leaves have a visible blue shine with a blue vein. In habitat it grows on wet rocks but also grows in rivers. Variations grow in rivers are smaller.
