During our field trip to west Kalimantan, we found another stream near where we found C. keei lined with carpets of cryptocorynes. Unfortunately, no spathes could be found to verify the species of the cryptocorynes we found. My explorer friend termed it as C. sp. 'West Kalimantan 4' in his blog, '4' refers to the 4th natural habitat we found during the field trip. Is this also C. keei? I will leave it to you to judge for yourselves what species this is.
