By the time the spathe bloomed, it had rotated another 180 degrees anti-clockwise. This phenomenon was not observed when compared to another cryptocoryne (i.e. C. nurii 'Central Pahang') which simultaneously flowered in the same tank during the same period.
Below are the close up photographs of the distinctive red crumpled surfaced limb of the spathe. The red colour extended beyond the sharped folded collar down the throat.
As usual, I cut opened the kettle to take photographs of the spadix, stamens, flap (valve), appendix, pistals, styles, stigmas, olfactory bodies, etc.When will it flower again?
























The habitat is a say less than 5m x 5m sandy mud pool (legs can easily sink in up to calf level) with water maybe about 10cm high and pH 6 to 6.5 (I thought it would be much more acidic but I was wrong!).
Apart from fighting against extinction due to human activities (i.e. redevelopment which would include land fill and cutting down of oil palm trees, etc), it also has to struggle to strike a delicate balance with other aquatic / semi aquatic plants to share the limited space within the mud pool.
