The weed that will remain un-named?

I have been curious to know more about how harvesting a bit of weed with your spinach could result is hallucinations and other ill health.   I see there was a bit more commentary on this yesterday, and I get the feeling that even if the weed is clearly identified, the authorities doubt it is a good idea to publicise it:

Australians are being urged not to seek out contaminated baby spinach products for a recreational high after more than 130 people who ate a range of fresh food items suffered symptoms including hallucinations and delirium.

Authorities were on Sunday night testing the weed believed to be responsible for the widespread recall of products containing spinach thought to have come from a farm in Victoria....

Symptoms can be severe and include delirium or confusion, hallucinations, dilated pupils, rapid heartbeat, flushed face, blurred vision, dry mouth and skin, and fever....

Dr Brett Summerell, chief scientist at Sydney’s Royal Botanic Gardens, said it was hard to distinguish between many plant species when they were small. He suspected toxic plants including nightshades could be to blame.

“There are lots of plants that could do this – lots of weeds that are relatives to potato and tomato,” he said.

“This is likely to be a nightshade. When young, they are just a few dark green leaves which is probably not that much different to spinach. You’re harvesting all these leafy greens now at a very young age, sometimes it can be quite difficult [to identify].”

Summerell said farmers were facing the extra challenge of an explosion of weeds right across the country after months of rain and floods....

Summerell warned people not to go searching for the contaminated products or pick and eat weeds they could not identify in search of a cheap high.

“People might be tempted to go out picking weeds thinking that they’ll get some sort of high [but] it’s really important to remember yes, there might be a hallucinogenic side to this, but there’s a whole lot of really horrible health issues,” he said.

Update:  well, that took a while, but it has been named:  thornapple.  Never heard of it, and kind of surprising that this is the first time it has happened.
