Cucumis myriocarpus: prickly paddy melon

Jennifer invites us interpret the theme in any way we like, so I have.

I haven’t seen these little golf ball sized melons growing in our part of Victoria before – they are common in the drier, hotter parts in the north-west. This is just a little patch of two vines,  the seeds probably came from bird poo. I’ll have to pull them up before long, else they will become an infestation if the weather suits them next year.

Wikipedia says …

Cucumis myriocarpus, paddy melon or prickly paddy melon is a prostrate or climbing annual herb native to tropical and southern Africa. 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.

The fruit and foliage are toxic due to the presence of cucurbitacin …

The melon is a weed in Australia and in California, where it may also be known as prickly paddy melon, bitter apple, gooseberry gourd and gooseberry cucumber.

Cucumis myriocarpus (paddy melon) is often confused with Citrullus lanatus (the Afghan or camel 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. 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.

Paddy and Afghan melons (collectively referred to as wild melons) sometimes occur in mixed infestations in Australia. They vary only slightly in colour and appearance, with the Citrullus lanatus leaves slightly more variegated than those of Cucumis myriocarpus. Fruit size is the clearest identifying factor. However, management of all wild melons is similar, apart from some variation in sensitivity to glyphosate. 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.

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

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

Without hooking up my old hard drive, my acorn photos are the only images bearing any possible hint of melon.

I started blogging in an effort to keep the old brain cells alive. I'm writing a fantasy series, I take more MOOCs than I can handle, and am trying to get my Nikon D3000 off auto. I live in Victoria, Australia, with my husband and our dog, Vika.

  1. Rather unsavoury, shame there isn’t some kind of use for them, seeing as they grow so easily. I’ve never seen them before.

  2. I like the paddy melon better than the pademelon, Christine — the little beasts are eating all the grass our animals need to survive! Last night Paul turned on the balcony light and there were FOURTEEN of them eating the grass in the sheep paddock 😦

      1. I thought from the picture that they were smaller than that. We have so many different types of animals in Australia, they are amazing.
