This
mysterious flower in all its splendour seduces the mind leading it into
tropical worlds of vivid colours and magical realms. There are about
20.000 naturally occurring species of orchids currently in existence
of which a significant number grow among the forests and meadows of
Italy. The region of Romagna alone accounts for forty species of various
breeds and are all protected by the regional law n° 2 of 1977.
The
flower consists of two parts; the outside part, the calyx, making up
three sepals arranged in a triangle. Inside, sit two petals, often very
tiny, and the stamen, being the more noticeable part, responsible for
attracting pollinators. The leaves are oval in shape, with veining which
joins at the apex.
Orchid
reproduction is dependant upon insects, attracted by the unusual scent
the shape and the colour of the flowers. Bees, bugs and butterflies
settle on the stamen to feed from the nectar in the spur. Some orchids,
such as the Ophrys, do not have nectar, and in order to attract insects
they take the mimic the appearance of the female insect and emit a scent
similar to that secreted by the female The insects deceived by the smell
try mating with the flower, becoming covered in pollen, which they then
deposit onto another orchid of the same species, mistaken for another
female. After fertilization the flowers fades, while the ovaries develop
the seeds that will be carried by the wind.
They
have no supply of nourishment: that will be provided by some species
of micro fungus with which many orchids will live in symbiosis until
the formation of the bulb. Orchids lacking in chlorophyll will live
in symbiosis for the duration of their existence. Such symbiosis takes
the name of “mycorrhiza”. A heritage to protect: orchids
are best observed close up in order to appreciate their beauty, their
vivid colours and their strange shapes; but they are best left in their
natural surroundings. They are delicate plants and so would find it
difficult to adapt in a different environment.
