Orchideen Maxillaria Porphyrostele
We admire the orchids for their beauty. Each flower is a work of art of complex construction.
Worth it – yes, we are actually not spared, let us make friends with him to penetrate a little deeper into his secret. Here we want J.W. follow from Goethe, who in his morphological writings traces the orchid blossom back to simpler forms: “Who could piss us off?, if we wanted to call the orchids the monstrous Liliazeen?“
Take a tulip, a Liliaceae – blossom, at hand. The number of three determines the structure of the flowers: 6 Petals (3 outer and – alternating with them – 3 inner), 6 Stamens (actually ever 3 in 2 Circles), a triple ovary; Radial symmetry.
What of this do we find again in the orchid blossom? ? For this purpose, let's look at the adjacent picture and illustration 4 of the appendix. With Angraecum sesquipedale we can clearly 3 outer (Sepalen) as 3 inner petals (Petalen) distinguish, which lie on top of each other like two three-pointed stars. It is now characteristic of the orchids, that the bottom of the 3 Petals opposite the 5 other petals have undergone a profound transformation and become a lip, The sink give, has become. Another deviation from the basic pattern of the Lily flower is the loss of 5 Stamens and the fused together of the remnant with the stylus to form a column. With Maxillaria porphyrostele this is, As the name indicates, from purple to brownish color. With the transformations, the radial symmetry of the flower is also lost, it takes on a clearly dorsiventral shape.
From the tulips- It seems a long way about the orchid blossom, to be an unbridgeable step. However, in the original Neuwiedea orchid we have before us a connecting link between the two. She still owns 3 Stamens, the dorsiventrality is only weakly indicated; we also meet with the genus Paphiopedilum 2 fertile stamens.
