This time round, we reached a smaller river in a forest where we found cryptocorynes growing both submersed and emersed inside as well as along the banks of the river. Don't be decieved by the gentle looking river, my friend recently went back there and found the entire river flooded.
These are photographs of the leaves of the submersed specimens. They are basically green in colour with faint markings.Note that the leaves had elliptic oval shape and that the base of the leaves ranged from cuneate to round to cordate.
The emersed portion of the banks were more muddy, rather different from the base of the river. Maybe the sand and clay at the base of the river were washed down from some other sections of the river?
The current recorded species in Johor state are C. nurii, C. schulzei, C griffithii, C. longicauda, C. x.purpurea (considered by some as a hybrid between C. griffithii and C. cordata), C. cillita as well as the famous and possibly extinct (in the wild) C. sp. Kota Tinggi (considered by some as a hybrid too). This accounted for about half the species which could be found in Malaysia Peninsula, and majority of the above stated could be found along the eastern coastal side of Johor state.
Could these specimens we found be belonging to one of the species stated above such as C. griffiithii or could it be something new? My explorer friend compared the submersed leaves of these specimens to those shown on "the crypt pages" and felt that there might even be a possibility that this could be comparable to C. decus-silvae. Due to the high variability in terms of leaves appearance even within the same species, only experts cultivators of cryptocorynes can help to solve this mystery by quickly blooming the specimens to confirm how the spathe looks like. I shall term it as C. sp. Sedili 6 first (don't bother about the numbering, it is just my internal system to tie in with how my explorer friend identify the location).
