C. bullosa in other rivers near Sungai Seblak

We located C. bullosa in 2 other rivers near to the Sungai Seblak, I shall not reveal the names of the rivers here. Below are some photographs of the 1st river which looked slightly blackish. The C. bullosa found there were mainly in submersed form.

The 2nd river had both emersed and submersed C. bullosa, below are some photographs of it.

What surprised me was that C. ciliata could be found growing alongside C. bullosa in the same river.

C. bullosa 'Sungai Seblak'

We managed to locate Sungai Seblak (not Sibiak) in Sarawak. I read on the Internet that this river had C. bullosa and the information was correct.

C. bullosa could be found growing on the islands in the river.

The pH of the water was about 5.5 and the river bed was sandy.

The submersed specimens seemed to be growing better than the emersed specimens.

The below are some close up shots of the strongly bullated greenish leaves with white centre veins.

From the below photograph, you probably could guess that these cryptocorynes were deeply rooted. Again, only the limb of the spathe we located was protruding out of the river bed, we had to dig out the specimen to be able to take the photographs of the entire spathe.

The below is the photograph of an immature seed pod.

As usual, we cut open the spathe to take the photographs of the internal female and male flower. As the collar of the spathe was close to the river bed, the river water could easily enter the kettle as can be deduced from the wet internal walls of the kettle.

C. bullosa 'Pakan'

We passed by a river around Pakan area in Sarawak and saw an island in the middle of the river. From far away, the island looked like it was covered with pebbles.

Luckily, we decided to go nearer to confirm and was pleasantly surprised when we discovered cryptocorynes growing camouflage among the pebbles. There were both emersed and submersed forms present.

The river bed was sandy and the pH of the water was about 6.5.

Below are some close up shots of the leaves and roots.

From above you could tell that the cryptocorynes were quite deeply rooted, i.e. the white portions of the petioles were all buried within the substrate. We managed to locate a spathe with just the limb portion sticking out of the river bed and therefore had to dig out the specimen in order to photograph the entire spathe. After some discussion, we concluded that it should be C. bullosa. It was the 1st time I found C. bullosa.

We also found a "delicious" looking fruit.

As usual, we cut open the spathe to expose the male and female flower.
