Cryptocoryne cordata siamensis NJT 02-52

SIA - Crypt. cordata siamensis NJT 02-52

Cryptocoryne cordata siamensis 'Neils Jacobsen collection of 2002 location #52'.

Quadraploid (2n=68); different from the usual diploid (2n=34) form cordata cordata or other forms of cordata siamensis (2n=102).

Forms of cordata with 2n=68 are found all over Borneo; this stands out so far as the sole 2n=68 population of any cordata in Thailand. Curiously, it looks no different from a normal diploid plant.
