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).

Contents

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. [4]

Description

The six species of Ripogonum [5] are perennials, either vines or shrubs. The leaves, which may have several different arrangements, lack stipules. The stems may have prickles. The Australian species are bisexual; others are unisexual. Individual flowers have six white to pale green or yellow tepals. The ovary has three locules with two ovules per locule. The fruit is a berry with a few brown seeds. [6]

Taxonomy

In 1769, during explorer Lieutenant James Cook's first voyage of discovery, botanists Joseph Banks and Daniel Solander collected specimens of "supplejack" ( Ripogonum scandens ) in New Zealand. The species was described in Solander's unpublished manuscript Primitiae Florae Novae Zelandiae and was illustrated by Sydney Parkinson. [7] Cook again visited New Zealand in 1773 during his second voyage. While anchored at Dusky Bay (now Dusky Sound) in the South Island of New Zealand, he remarked in his journal: [8]

In many parts the woods are so over-run with supplejacks, that it is scarcely possible to force one's way amongst them. I have seen several which were fifty or sixty fathoms long.

During this voyage naturalist Johann Reinhold Forster, assisted by his son Georg Forster collected plant specimens, the elder Forster offering the following description in his journal: [9]

A kind of climbing plant called the supple Jack by our Sailors, on account of its pliancy, bears red berries, something similar to cherries, & runs up the highest trees, climbs over to another, & after having made its way over many of them, it often comes again down & strikes fresh roots.

In 1776, the Forsters published the genus Ripogonum in the second edition of their Characteres Generum Plantarum with Ripogonum scandens as the type species. [2] [3] [10] The name Ripogonum is derived from the Greek words ῥιπος (rhipos, wickerwork, referring to the long shoots) and γονυ (gonu, jointed), from the jointed appearance of the stems. [11]

Because the Greek word ῥιπος begins with an aspirate rho rather than plain rho, classical scholars preferred to transcribe it with rh- rather than r-. [12] Consequently, some early botanists treated the Forsters' [13] spelling as an error to be corrected and the spelling Rhipogonum was used. Which spelling is correct depends on the interpretation of Article 60 of the International Code of Nomenclature for algae, fungi, and plants, which recommends that the classical transcription rules should be followed when forming new names (Rec. 60A) and also that "the original spelling of a name or epithet is to be retained, except for the correction of typographical or orthographical errors". [14]

It has been stated that the Forsters' spelling is probably deliberate and should not be liable to correction in the same way as an accidental typographical error would be. [15] The International Plant Names Index treats the spelling Rhipogonum as an "orthographic variant", [3] and the Index Nominum Genericorum database uses the spelling Ripogonum, [16] as does the World Checklist of Selected Plant Families as of March 2014. [17]

Phylogeny and classification

Until recently, Ripogonum was included in the family Smilacaceae (and earlier in the family Liliaceae along with other lilioid monocots) but it has now been separated into its own family Ripogonaceae. [1] The family name was first formally defined by Conran and Clifford in 1985. [4] Armen Takhtajan later created the same family without realising it already existed. [18]

Molecular phylogenetic studies since the early 2000s have consistently shown a close relationship between the four families Ripogonaceae, Philesiaceae, Smilacaceae and the modern narrowly defined Liliaceae. This relationship was confirmed in a 2013 study, which produced the cladogram: [19]

Liliaceae

Smilacaceae

Ripogonaceae

Philesiaceae

The authors suggested that the Ripogonaceae and Philesiaceae could be combined into a single family based both on the genetic similarity of their plastids and common morphological features. [19] The APG III system treats them as two separate families in the Liliales, both distinct from Smilacaceae. [1]

Species

Ripogonum contains only six known species as of July 2013. [2] [11] [20]

Uses

Some species of this genus are used for constructing baskets, [21] ropes, [22] and fish traps [23] by indigenous peoples. In Australia and New Zealand, Ripogonum berries are known foods for some species of mammals [24] and birds. [25]

Ripogonum scandens has a fibrous root rich in starch and used as a beer flavouring. [26] Known to the Māori of New Zealand as kareao or pirita, a concentrated decoction of the supplejack root has a sweetish sarsaparilla-like scent and flavour and is soothing to the throat. [27] It was also used in treating bowel complaints, fever, rheumatism and skin diseases. [28] The edible small berry is dry and insipid but the cooked young shoots reportedly taste like fresh green beans. [26] The sap is also edible. [26]

Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription varying greatly from one taxonomist to another. Previous members of this order, which at one stage included most monocots with conspicuous tepals and lacking starch in the endosperm are now distributed over three orders, Liliales, Dioscoreales and Asparagales, using predominantly molecular phylogenetics. The newly delimited Liliales is monophyletic, with ten families. Well known plants from the order include Lilium (lily), tulip, the North American wildflower Trillium, and greenbrier.

<span class="mw-page-title-main">Smilacaceae</span> Family of flowering plants

Smilacaceae, the greenbriers, is a family of flowering plants. While they were often assigned to a more broadly defined family Liliaceae, most recent botanists have accepted the two as distinct families, diverging around 55 million years ago during the Early Paleogene. One characteristic that distinguishes Smilacaceae from most of the other members of the Liliaceae-like Liliales is that it has true vessels in its conducting tissue. Another is that the veins of the leaves, between major veins, are reticulate (net-shaped), rather than parallel as in most monocots.

Hemerocallidoideae is the a subfamily of flowering plants, part of the family Asphodelaceae sensu lato in the monocot order Asparagales according to the APG system of 2016.

The largest genera in the group are Dianella, Hemerocallis (15), and Caesia (11).

<span class="mw-page-title-main">Coronariae</span> Historical term for group of flowering plants, including lilies

Coronariae is a term used historically to refer to a group of flowering plants, generally including the lilies (Liliaceae), and later replaced by the order Liliales. First used in the 17th century by John Ray, it referred to flowers used to insert in garlands. Coronariae soon came to be associated with Liliaceae in the Linnaean system. The term was abandoned at the end of the 19th century, being replaced with Liliiflorae and then Liliales.
