Six new Cryptocoryne taxa (Araceae) from Kalimantan, Borneo

Abstract

Five new species and one new variety of Cryptocoryne (Araceae) from the Schwaner mountains (W Kalimantan) and the Müller mountains (W and C Kalimantan) are described. These new taxa makes a very interesting and unique addition to the genus Cryptocoryne. Two of the species have surprisingly low chromosome numbers: C. bastmeijeri with 2n = 14 and C. isae with 2n = 10. A key to the Cryptocoryne taxa of Borneo is provided.
