A new species of rheophytic palm from New Guinea

Abstract

A new rheophytic palm, Hydriastele rheophytica, is described for New Guinea. Although other New Guinea palm species occur on the banks of fast flowing rivers, they also occur on adjacent slopes and in other locations. Hydriastele rheophytica is confined to stream edges as part of a rheophytic community. This elegant species has been in cultivation in north Queensland for several years, proving adaptable to, and thriving in, many conditions.
