I have not went for a field trip for more than a month (maybe will make a short trip next weekend to Sarawak?) and have not had any cryptocorynes blooming in my cultivation tanks so I have nothing much to update except maybe some photographs of the leaves of C. scurrilis 'Indragiri Hulu Sumatra' in my cutivation tank:
My explorer friend found 3 different looking types of specimens from around the same location then. Well they might be the same species or different, I can only know when they flower. They are planted in 3 different pots currently as shown below.
