Ripogonum

Ripogonum (sometimes Rhipogonum) is a genus of flowering plants confined to eastern Australia, New Zealand, and New Guinea. Until recently this genus was included in the family Smilacaceae, and earlier in the family Liliaceae, but it has now been separated as its own family Ripogonaceae (sometimes Rhipogonaceae).

Like most species of the closely related Smilacaceae, most species of Ripogonum are woody vines. Differences from Smilacaceae include that Ripogonum lacks stipules, it has a wet rather than dry stigma, its seeds and leaves contain starch, and its guard cells contain oil.
