Studies on Schismatoglottideae (Araceae) of Borneo LXI: Aridarum chamaesyce, a new species, and corrections to an earlier interpretation of Aridarum montanum

 

Wong Sin Yeng & Peter C. Boyce

 

ABSTRACT

Aridarum chamaesyce S.Y Wong & P.C. Boyce, sp. nov. is described based on collections from north western Borneo hitherto incorrectly determined as Aridarum montanum. An updated description for A. montanum is given, and both Aridarum chamaesyce and A. montanum are illustrated from living plants. A key to the four species of the Aridarum Clade is offered.
