Cucumis myriocarpus, the gooseberry cucumber, [1] gooseberry gourd, [2] paddy melon, Mallee Pear or prickly paddy melon is a prostrate or climbing annual herb native to tropical and southern Africa. [3] It has small, round, yellow-green or green-striped fruit with soft spines, small yellow flowers and deeply lobed, light green leaves. The melon occurs in disturbed soil and cleared or bare areas, and thrives on summer moisture. [3]

The fruit and foliage are toxic due to the presence of cucurbitacin. The plant is toxic to humans as well as to horses, sheep, cattle and pigs and it has been associated with stock deaths. [4] It has been used by humans as an emetic. [5] There are records of poisoning occurring in humans. [6]

The melon is a noxious weed in Australia and in California, where it may also be known as prickly paddy melon, bitter apple, gooseberry gourd and gooseberry cucumber. [4] [5] [7] [8] One of many invasive species in Australia, it is highly damaging to the economy, with the farmers bearing most of the cost. [9] [10]

Cucumis myriocarpus (paddy melon) is often confused with Citrullus lanatus (the Afghan melon, camel melon or bitter wooly melon) in Australia, where both species are introduced. Cucumis myriocarpus has many small fruit, hidden under the leaves. The fruit are smaller than a golf ball and green in colour, developing to yellow on maturity. The larger melons commonly seen on roadsides in rural Australia are in fact Citrullus lanatus, a wild relative of the watermelon. [3] [11] [12] The confusion is widespread in Australia, such that in common parlance, the term "paddy melon" is understood to mean the larger green/yellow fruit of the Citrullus lanatus. Children in rural Australia often use the fruit of this plant as an opportunistic source of entertainment, for example by throwing it at each other's feet, or squeezing the fruit to shoot the seeds at each other[ citation needed ].

Paddy and Afghan melons (collectively referred to as wild melons) sometimes occur in mixed infestations in Australia. [3] They vary only slightly in colour and appearance, with Citrullus lanatus leaves being a little more variegated than those of Cucumis myriocarpus. [13] Fruit size is the clearest identifying factor. However, management of all wild melons is similar, apart from some variation in sensitivity to the herbicide glyphosate. [4] [13] Mechanical removal of small infestations is the simplest control method, and cultivation at early stages of growth can be effective. Large infestations are sometimes controlled by the spray-graze method, in which plants are sprayed with a sublethal dose of hormone herbicide to make them more palatable to stock, and the area is heavily grazed three days later. Toxicity is managed by making other feed available. [3] [6]

Both wild melon species have a similar unpleasant odor when broken or disturbed. That makes them less palatable to stock, so poisoning tends to occur only when little other feed is available. [6]

The plant occurs in Spain, where it is naturalized and known by the common names of habanera or sandía habanera. [5]

<span class="mw-page-title-main">Cucumber</span> Species of flowering plant that produces cucumbers

The cucumber is a widely-cultivated creeping vine plant in the family Cucurbitaceae that bears cylindrical to spherical fruits, which are used as culinary vegetables. Considered an annual plant, there are three main types of cucumber—slicing, pickling, and seedless—within which several cultivars have been created. The cucumber originates in Asia extending from India, Nepal, Bangladesh, China, and Northern Thailand, but now grows on most continents, and many different types of cucumber are grown commercially and traded on the global market. In North America, the term wild cucumber refers to plants in the genera Echinocystis and Marah, though the two are not closely related.

<span class="mw-page-title-main">Melon</span> Type of fruit

A melon is any of various plants of the family Cucurbitaceae with sweet, edible, and fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Botanically, a melon is a kind of berry, specifically a "pepo". The word melon derives from Latin melopepo, which is the latinization of the Greek μηλοπέπων (mēlopepōn), meaning "melon", itself a compound of μῆλον (mēlon), "apple", treefruit " and πέπων (pepōn), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes.

<span class="mw-page-title-main">Citron melon</span> Species of fruit and plant

The citron melon, also called Citrullus lanatus var. citroides and Citrullus amarus, fodder melon, preserving melon, red-seeded citron, jam melon, stock melon, Kalahari melon or tsamma melon, is a relative of the watermelon. It is from the family Cucurbitaceae which consists of various squashes, melons, and gourds. Native to arid landscapes of sub-Saharan Africa, it has been a wild source of nutrition and hydration for humans for an extraordinarily long time. Its fruit has a hard white flesh, rendering it less likely to be eaten raw in the modern era; more often it is pickled or used to make fruit preserves, and is used for cattle feed. It is especially useful for fruit preserves, because it has a high pectin content.

<i>Citrullus ecirrhosus</i> Species of fruit and plant

Citrullus ecirrhosus, commonly known as Namib tsamma, is a species of perennial desert vine in the gourd family, Cucurbitaceae, and a relative of the widely consumed watermelon. It can be found in both Namibia and the Cape Provinces of South Africa, in particular the Namib Desert. It is the sister species to the bitter melon, Citrullus amarus with which it shares hard, white and bitter flesh.

<span class="mw-page-title-main">Cucurbitacin</span> Class of biochemical compounds

Cucurbitacins are a class of biochemical compounds that some plants – notably members of the pumpkin and gourd family, Cucurbitaceae – produce and which function as a defense against herbivores. Cucurbitacins and their derivatives have also been found in many other plant families, in some mushrooms and even in some marine mollusks.

<i>Cucumis melo</i> Species of plant

Cucumis melo, also known as melon, is a species of Cucumis that has been developed into many cultivated varieties. The fruit is a pepo. The flesh is either sweet or bland, with or without a musky aroma, and the rind can be smooth, ribbed, wrinkled, or netted. In North America, the sweet-flesh varieties are often collectively called muskmelon, including the musky netted-rind varieties and the inodorous smooth-rind varieties, and cantaloupe usually refers to the former type. However, muskmelon in a narrow sense only refers to the musky netted-rind type, also known as North American cantaloupe, while the true cantaloupe is the European type with ribbed and often warty rind that is seldom grown in North America.

Paddy melon is a common name for two species of plants in the melon family which are invasive in Australia:

Wild melon is a common name used for several species of plants in the melon family (Cucurbitaceae) which grow outside of cultivation

<i>Melon necrotic spot virus</i> Species of virus

Melon necrotic spot virus (MNSV) is a virus that belongs to the genus Gammacarmovirus of the family Tombusviridae. It has been observed in several countries of the Americas, Africa, Asia, and Europe. It is considered to be an endemic virus in greenhouses and field productions of Cucurbitaceae crops, including melon, cucumber, and watermelon. MNSV is mainly spread through infected soil, seedlings, insects, and by the root-inhabiting fungus vector Olpidium bornovanus. Symptoms vary between Curbitaceae crops, but generally consist of chlorosis, brown necrotic lesions, leaf wilt, fruit decay, and plant death. Management of the disease consists of preventing infection by rotating fields and crops, steam sterilization, and disposal of infected plants. Also, treated seeds with heat or chemicals are efficient in preventing infection. MNSV is important in melon plants as it causes vast economical damage worldwide reducing significant yields.

<i>Lolium rigidum</i> Species of grass

Lolium rigidum is a species of annual grass. Common names by which it is known include annual ryegrass, a name also given to Italian ryegrass, rigid ryegrass, stiff darnel, Swiss ryegrass and Wimmera ryegrass. It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia, where it is also a serious and economically damaging crop weed.

Kalahari melon oil also known as Tsamma (Damara/Nama), wild watermelon (English), bitterboela, karkoer (Afrikaans), wild watermelon, makatane (Setswana) or Mokaté oil, is a plant oil, extracted from the seeds of the Kalahari melon (Citrullus vulgaris), which is endemic to the Kalahari Desert, spanning Namibia, Botswana and South Africa. Being one of 1,200 varieties of melon, Kalahari melon oil is distinct from regular watermelon seed oil. The seed of the Kalahari melon consists of approximately 50% oil, 35% protein and 5% dietary fibre.
