Rhipogonum is the only genus of plants in theRhipogonaceae family in the order of the lily-like (Liliales). Another notation used is Ripogonaceae and Ripogonum J.R. Forst . & G.Forst. There are six ripogonum species.

description

Rhipogonum species are woody plants: climbing shrubs or lianas . They often form short, woody rhizomes . The shoot axes are often thorny, but there are no tendrils. The most opposite, rarely alternate or in whorls arranged leaves are simple. Petioles are present or absent. The leathery leaf blade is reticulate with three strong main nerves.

The flowers are usually in axillary racemose or spiked , rarely in terminal paniculate inflorescences . The relatively small, hermaphrodite, radially symmetrical flowers are threefold. The six very small, free bloom cladding sheets are shaped identically ( perigone ). There are two circles, each with three-free, fertile stamens . Three carpels have become a top permanent ovary grown with two ovules per ovary chamber. The only short style ends in a scarcely recognizable three-lobed scar. The seeds are almost round, only slightly angular.

There are berries formed. They contain one to a few seeds.

Distribution map

Systematics and distribution

The area of ​​the genus extends from New Zealand over eastern Australia ( Queensland , New South Wales and Victoria ) to New Guinea .

The genus Rhipogonum J.R. Forst. & G.Forst. was formerly in the Vent family of Smilacaceae . classified. The Rhipogonaceae family was only established in 1985 by John Godfrey Conran & Harold Trevor Clifford . The Rhipogonaceae are closest to the Philesiaceae Dum. related, with which they have the reticulate leaves in common.

There is only one genus in the Rhipogonaceae family, Rhipogonum with around six species:

• Rhipogonum album R.Br. : It occurs in Australia from northern and southern Queenlsland to eastern Victoria and in New Guinea.
• Rhipogonum brevifolium Conran & Cliff. : It occurs in Australia from northern and eastern Queensland to New South Wales.
• Rhipogonum discolor F. Muell. : It occurs in Australia from southeast Queensland to New South Wales.
• Rhipogonum elseyanum F. Muell. : It occurs from eastern Queensland to New South Wales.
• Rhipogonum fawcettianum F. Muell. ex Benth. : It occurs from southeast Queensland to eastern New South Wales.
• Rhipogonum scandens J.R. & G.Forst. : It occurs in New Zealand.

Use by animals and humans

It is known that in Australia and New Zealand the berries are eaten by some mammal and avian species.

Plant parts of some Rhipogonum species are used by the indigenous peoples to make baskets, ropes and fish traps.

The "rhizomes" of Rhipogonum scandens are rich in starch and are used to flavor beer . Although the small berries are dry and taste bland, they are eaten. The cooked young shoots taste like green beans. The sap from the stem is also edible.

Rhipogonum scandens is used medicinally.
