Rhipogonum

Rhipogonum is a genus of flowering plants in the family Ripogonaceae. It is native to Australia and New Zealand. The genus was formerly included in the Smilacaceae family, but molecular phylogenetic studies led to its reclassification into its own family. There are currently four recognized species within the genus Rhipogonum. These plants are typically woody vines or scramblers, often found in rainforests and damp woodlands. Their leaves are usually arranged alternately along the stem and can vary in shape depending on the species, though they are often ovate or elliptical. The flowers are generally small and inconspicuous, borne in clusters. They have six tepals, which are often white or greenish. The fruit is a berry, typically red when ripe. The common name for Rhipogonum species in New Zealand is 'supplejack'. These plants have a history of use by indigenous peoples for various purposes, including medicinal applications and for crafting. The species are characterized by their climbing habit and their ability to adapt to shaded forest understories.
