The World’s Rarest Trees

July 2,2010 by

As I was blissfully looking out my window (trying to think of a compelling blog topic) I noticed a few beautiful trees.  It’s a gorgeous sunny summer day in Boulder and with the fair amount of rain we’ve gotten so far this summer, things are reasonable green still!  I started to wonder about what the rarest tree in the world is….here’s what I came up with from a little internet searching:

Pennatia baylisiana

Pennantia baylisiana
There is apparently only 1 tree in the wild, located on one of the Three Kings Islands, off the coast of New Zealand.  It is listed in the Guinness Book of World Records as one of the world’s rarest plant.

Ramosmania rodriguesii

Ramosmania rodriguesii (Cafe marron)
Also known as cafe marron, this rare tree is native to the small island of Rodrigues in the Indian Ocean.  There is only one image of the plant in the wild, taken in 1877.  The photo here is from the Kew Gardens, where it regularly flowers.  In 2003 horticulturists were able to pollinate the flowers, resulting in a fruit with viable seeds.

the Parijaat tree
This tree is so rare I couldn’t find a photo of it!  It is a type of baobab tree, native to India.  There are many legends related to this special tree and its beautiful white flowers.

Abies beshanzuensis
Abies beshanzuensis
There are only 3 known trees in the wild (as of 1988).  A native of SW China, this tree has not had success in captivity.  It is listed as critically endangered on the IUCN Red list.

Hyophorbe amaricaulis

Hyophorbe amaricaulis palm
This extremely rare tree is a type of hurricane palm and is found exclusively on the island of Mauritius, an island nation in the southwest Indian Ocean.  There is only one surviving tree, shown here.  It stands about 12 meters high with a thin grey trunk and reportedly produces white/cream flowers (though years of efforts have not resulted in fertile tree offspring).

I do not know if it is rare enough for this list but the half hearted pine tree is a very rare tree. They grow very slow and have incredible hard wood,their needles are not pointy, and their pine cones are shaped like hearts. There are only about 1000 left on earth two of which are in my own yard. (good luck find any documents or pictures online, I spent hours and came up empty handed)

This is very interesting. I hope these trees will get cut down soon so people would focus more on cancer research.

What about the Bois Dentelle which there are only two of in existence although scientist were able to create two in a tree nursery.

Wow, how narrow minded. Perhaps one or more of these trees might be the answer to a treatment or cure for cancer.
