First identified as a potential new species by the botanist Heff-Warburg in the 1930's growing in a small lay-by, the tree has only just been confirmed as indeed being a completely new species following biochemical analysis by the University of Wales.
One of 110 trees of the species discovered in the area so far, it has been given the Latin name of Sorbus admonitor by those who name such things at the National Museum in Cardiff. This means 'to admonish' I am reliably informed by people who actually understand Latin.
Of course, most of us are not Latin boffins which is why trees have common names. In this case the Latin name provides a clue as to why it has been called the 'No Parking Whitebeam.'
It appears that the very first tree to be identified way back in the 1930's had a no parking sign pinned to it.
As part of the celebrations to mark the 150th year since publication Charles Darwin's On the Origins of Species, botanists have been busy discovering no less than 14 new types of tree around the UK.
They are being named either after the person who first discovered them or the place that they were discovered in. Some are being named because of the way they look, and this one looked like a no parking sign I guess.
Dr Tim Rich who is the Head of Vascular Plants at the University of Wales says that the No Parking Whitebeam is easy to identify as it has "...much more strongly lobed leaves." That and the traffic wardens hanging around the roots.
