The Function

Flowers sprout above the pseudobulbs (example Encyclie), at its base or the same pseubobulbo (Erie example). The variability of form of different orchids, nature is dictated by the fact that often have to live in extreme conditions. This makes Orchid belonging to the same genus, have adapted the body itself in extremely different ways. Here are some examples: Dendrobium cucumerinum what has transformed their leaves in sort of sausage to accumulate water reserves to survive periods of drought. Dendrobium senile whose shaft is coated by a thick fluff that serves the plant to limit perspiration and therefore the dehydration. BLADES can be arranged in several ways in the plant.

They are normally alternate in the shaft and the shape can be very various: elliptic, lanceolate, linear, triangular, etc. Often they are fleshy and in this case assume the function of organs of collection in the vegetative rest periods. ROOTS the roots of orchids are different according to gender. We see in detail: orchids stocked only aerial root (epiphytic orchids) what grow enclaved trees used as backup. If you are unsure how to proceed, check out Slayer. The roots are in the air and have the feature of having a type of headgear in the terminal part and are coated by a spongy tissue called velamen what endowed of chlorophyll, photosynthesis develops and absorbs damp vapor of the atmosphere. The best-known and remembered epiphytic Orchid types are: Cattleya, Vanda, Odontoglossum. Well firm and in-depth orchids on the ground (terrestrial orchids), disseminated in climates warm, where the roots are firm on Earth and through them, the plant absorbs nutrients.

There are so-called formations in terrestrial orchids tubers formed from the merger of some roots that we can find black color when they have fueled the year-round or white button when they are intended to provide nutrients to the button of the following year. They are typical ejemplo:Cymbidium, Cypripedium, Paphiopedilum. There are also the intemedias which are semiepifitas orchids, plants that live on the branches and trunks of other plants or litofilas or rock what live on rocks covered by a subtle layer of fragments plants, mosses and lichens that have roots that are intermediate between those epiphytes and those landmines.
