Description
Summary:A new diploid variety, Cryptocoryne cordata var. wellyi from the Riau Province in Sumatera is described. Three interspecific natural hybrids are also described: the diploid C. ×ardyi, the triploid C. ×jambiensis and the tetraploid C. ×zukalii nothovar. sumateraensis, of which the tetraploid hybrid involves C. cordata var. diderici as one parent. The hybrids are sterile but propagate vegetatively, forming large stands. A key to the Cryptocoryne taxa of Sumatera is provided.
