Pahang was rather far from Singapore and we spent a day travelling up to Pahang and staying over for 1 night before commencing our pre "Chinese New Year house visiting" to the various cryptocoryne habitats. After visiting a fresh water lake with "sea-side" banks and a flooded swamp forest, we stayed over at a town flooded with swallows and had dinner and breakfast at the local Chinese coffee shops there.
The river had fine sandy base and a neutral pH.
One thing I always liked about visiting habitats with submersed specimens with bullate leaves was the view of how the pockets of undulations on the leaves retained the fine sand particles washed across the leaves by the water.
Specimens with leaves of various degree of redness could be found here.
As usual, we cut open the kettle of one of the spathe to capture the photographs of the male and female portion of the flower therein for you reference too.
Other C. affinis found at other habitats around west Pahang will be featured in separate postings.
