On a wild Tasmanian mountain there is a magnificent, recently discovered stand of Huon pine trees that has been called the world's 'oldest known living organism'. Newspaper reports have claimed that what looks like hundreds of trees densely covering one hectare (2.5 acres), is all part of the one tree, since all these 'trees' appear to have identical DNA. Over the years, it is believed, 'snow has forced its branches to the ground, where they have taken root'. (The Sydney Morning Herald, January 28, 1995, page 1.)
It is hard to see how a tree could be older than the time since the biblical Flood, so if its published age of 'more than 10,500 years old' were correct, then this would present a serious challenge to Old Testament chronology. In fact, some media reports claim the tree 'could be 30,000 or 40,000 years old'.

Ginkgo biloba. They are the only species left in their genus. They are ancient trees, according to the experts, they have been around for millions of years. While they have what appears to be fruit, they are actually not angiosperms (basically means that they don't have fruit). They are gymnosperms. Their seed has a fleshy coating and looks like a white plum. Supposedly, it has a fetid odor....but I never noticed an unpleasant smell from them. The trees are found in the wild only in a few locations in China...though for a while now they have been planted around the world because they are so resistant to pollution.
Pawpaw trees are pretty unique,also, even though they aren't that uncommon. Their blooms resemble black purses and are nothing like the blooms on the usual fruit tree. The fruit has a taste much like that of a banana. Like the Ginkgo, the Pawpaw's blooms are supposed to have a fetid odor, but I never have noticed it, and I have at least 10-20 of the trees.
I think this site has a few good pics of the ginkgo.

And this has pics of the Pawpaw and its fruit.

I met a horribly scarred man in the Carribean. As a child he had taken refuge under a manchineel (Hippomane manicella) tree. Manchineel is a pretty tree that produces a caustic sap that burns the skin. Some of Columbus' sailors sampled its fruits and died. Manchineels are rapidly becoming eradicated.

As a species, the bottle tree is pretty interesting, and useful too

My opinion: "visakoivu", a peculiar type of the common birch (Betula pendula) having a natural mutation which causes various figures inside its stem. This wood is very popular as a decorative timber in certain part of Scandinavia like in Finland.

i think its the talipot tree, which is a palm; it flowers only once every 60 years..however, there's a tree which has only 1 individual left in the whole world, it is found in Mauritius(my country) and its scientific name is Hyophorbe amarycaullis, attempts are being made to reproduce it....

Monkey puzzle trees! It's a puzzle to the monkey because (apparently) its the only tree a monkey can not climb.
