Really amazing trip... but I am quite surprised with the crypt found. Resembles to swamp grower as C. schulsei, griffithii, etc... due to the stripped marks, but it having cordate leaves. And growing together at C. striolata, which grows in more o less fast flowing streams, with weak acid water. Have you idea about the pH and hardiness of the water there??
By the way, I am quite interested to place aproximately the area where you found them in
Google Earth.
Following your references I found a big lake in the Batang Ai National Park and mark a point for the located, itīs the following pictures...
Am I right???
