[math-fun] mysterious tree and fruit
Hello, as you may know, most of the plants, fruits, etc do have a growing pattern when they grow, there are 3 sections in a banana, 5 sections in an apple, pineapple do have 5 and 8 spirals, daisies have 21 petals (most of the time), this is not knew material at all. But here is one that I have found in Nantes, it is a tree in a park, just beside a street. When I saw these <fruits> the first time, I thought these were tennis balls in a fluorescent green color. Not at all : these things grows on a tree : http://www.lacim.uqam.ca:16080/~plouffe/fruit/ They do NOT have any growing pattern at all. Does anyone has any idea what tree and fruit this could be ?? I asked many peoples and nobody came with an answer, I went to see wikipedia for exotic fruits as well without success. Simon Plouffe
Could it be this? http://images.google.com/images?q=Maclura+pomifera&ie=UTF-8&oe=utf-8&rls=org... "The fruit of the Osage orange tree (Maclura pomifera). These things weigh half a kilo and some people use them as insect repellants. Known as Osage oranges, brain fruit, hedge apples and hedge balls." --Joshua Zucker On Sat, Oct 11, 2008 at 7:52 PM, Simon Plouffe <simon.plouffe@gmail.com> wrote:

That's exactly that, so it is a variety of oranges then, I thougt we were invaded by these body snatchers...! thank you for finding this. Simon Plouffe
Although called the "Osage orange" it is not related to the fruit that we eat called orange. The Osage orange classification is: Order Urticales Family Moraceae – Mulberry family Genus Maclura Nutt. – maclura Species Maclura pomifera (Raf.) C.K. Schneid. – osage orange The fruit we eat called orange classification is: Order: Sapindales Family: Rutaceae Genus: Citrus Species: C. sinensis But I think we have now strayed far from math-fun On Sat, Oct 11, 2008 at 10:00 PM, Simon Plouffe <simon.plouffe@gmail.com> wrote:
