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.Citation: Wongso S., Bastmeijer J. D., Budianto H., Ipor I.

Highlights
The first thorough study of the genus Cryptocoryne Fisch. ex Wydler (Araceae) in Borneo was by the Italian botanist Odoardo Beccari in 1865 and 1867, surveying the species of Sarawak
Jacobsen), and eight new species, which were subsequently described by Engler (1879) and elaborated on three years later (Eng ler 1883)
Such habitats are limited in number, and inhabited by only a few other plant species adapted to seeping water, muddy soil and low light intensity
