I revisited the habitat of C. sp. 'Pahang 1' at the northern part of Pahang. The water in the large river is at almost the same level as when I first visited it more than 2 years ago. Both emersed and submersed specimens could be found growing along the banks of the river. No spathes could be found at all again. The cryptocorynes were growing among the fine roots of the trees along the banks making them very difficult to collect. The pH was surprisingly rather high at about 9.0.
Could these be miniature C. affinis judging from the looks of the leaves as well as the location the were found? They have great potential to be good foreground plants for planted tanks!
