Australia is home to the world's most painful plant to touch: the `stinging tree'. Even gently brushing the leaves of this tree can cause intense pain, an itching, burning sensation which in mild cases can linger for months, and in extreme cases can be agonising, even fatal.

Stinging trees belong to the same plant family as European stinging nettle. They are found on Australia's eastern coast, from Iron Range on Queensland's Cape York Peninsula to wet temperate rainforests of the south-east.

I don't know about the MOST poisonous.

Do NOT burn these poisonous plants! The smoke will irritate your skin badly, and if it enters your nasal passages, throat and lungs it will likely cause serious problems and could result in death.
Make SURE you do NOT use sticks from these plants as skewers to cook hot dogs or marshmallows! You will suffer a horrible death if you do.




Overview
The leaves of Poison Ivy, Poison Oak and Poison Sumac contain urushiol, an irritating oil that causes severe itching and blistering on contact. Poison Sumac causes an immediate reaction, but it may be many hours before a victim notices the effects of Poison Ivy and Oak.

Contrary to common belief, Poison Ivy or Oak is not contagious through contact with the blisters of a person who has broken out in a rash, since the blisters contain only body fluids. However, if an infected person still has the oil on their skin or clothing, it may be transferred thereby affecting others.

Many people say they're "not allergic" to these plants. About 20% of the population has little or no reaction after contact. However, one's immunity can change over time. It is best to just avoid these plants because though you may not be susceptible, you could transfer the oils to others who are.

I don't know about the most poisonous plant in terms of stinging (as in hairs the break off from the plant and into your skin). In terms of pain, most of the plants in the nettle family surely hurt and itch. There are also MANY plants that are toxic to consume (rosary pea being one of the most toxic).

However, in the United States there is an invasive noxious weed, I think originally from Europe, called Wild Parsnip (Pastinaca sativa). This plant contains a phytotoxin, meaning a poison that reacts with UV light. When you get the plant oils on your skin, the toxins will react with the sunlight and cause third-degree burns and blisters on your skin. The toxin can go systemic in your bloodstream and translocate to other areas of your body in extreme cases. If that doesn't sound bad enough, here's the part that makes it most dangerous: the reactions with sunlight cross-link your DNA thus the toxin is a known carcinogen that can build up in your system after repeated exposures. The scary thing is that most doctors don't know about this plant but it is all along the roadsides in the midwestern U.S.

i dont know that there are any plants which can be actually lethal just by a sting (I presume you mean like a nettle). Most would need to be ingested. If you are interested in poisonous plants there is the most fantastic poison garden within the Alnwick Garden, in Northumberland. Many of the plants are grown behind metal protective barriers due to their effect to skin. The people there will most def be able to help you on this matter if you want to look into it further. www.alnwickgarden.com.

Funny that. Me and my friends were talking about a plant in the UK.

The council were sent out to cut a load of it down because it was so acidic, that just touching it caused rashes.

Its name....

Hogwart (Where do you think they got the school name from in harry potter).

It's almost identical to cowslip. Except the cows always leave it alone of course.

Maybe not the most dealdy, but interesting that we have something like that in the U.K.
