Another interesting article and one close to my heart.
I did read a few years ago how a french Botanist discovered an orchid in madigascar called the angraecum(sp) something or other!! It was later nicknamed darwins Orchid.
It was a very unusual shape and the depht was close to one foot.
Darwin came to the theory that there had to be a moth out there with a proboscis long enough to pollenate the flower.
His theory went unproven until 20 or 30 years after his death.
Unbelievable mind.
