ABSTRACT

The Cryptocoryne species of the Malay Peninsula mainly belong to the 2n = 34 chromosome group in the southern areas and the 2n = 36 chromosome group in the northern. The identification of the different species has mostly been straightforward, but in a number of cases it has proven difficult, these representing natural interspecific hybrids. Our results show that artificial hybrids are easily obtained, and it is possible to resynthesize the naturally occurring interspecific hybrids. The study also points out that it should be possible to find and identify more naturally-occurring hybrids than those presently known from the Malay Peninsula.
