Orchid Leaves

The absence of such bulbs in certain orchids, for example in species of the genus Pafiopedilum (Paphiopedilum), suggests that the nature of "Intended" to spread the plants in the same zone with humid climate throughout the year. Bulbs have a different size and shape, from ovate like Lycaste (Lycaste) and odontoglossumov (Odontoglossum), or flattened, as in individual ontsidiumov (Oncidium), rounded up (many species of the genus Encyclia). At the same time there is an orchid (Dendrobium, epidendrumy) with thin or thick, cylindrical, long bulb. On top of pseudobulbs bear leaves and 1, 2, and more. Elongated bulbs covered with leaves all over or just above. By orchids with sympodial form of the vast majority of genera, among which are popular in ornamental horticulture, as Odontoglossum, Encyclopedia, Cymbidium, Ontsidium, Cattleya and Dendrobium.

Orchid Leaves have different shapes and textures, which are considered a reflection of adaptive reactions of different genera and species of orchids to the specific circumstances of the environment. Y some species they are not thick, with extensive evaporation plane, while others – the thick, fleshy and serve as repositories of moisture. A small number of species, the leaves are reduced to small scales. Absolutely all of these plants Leaf veins are parallel to each other – an indicator saying that they belong to the monocots, which include as sedges, grasses, lily. The length of the existence of the leaves is very different: some it is limited to 1 im growing season, leaves others live two or three seasons, with some – for many years.

The roots of orchids have relatively thick, fleshy.

Their main function, like all other plants – water absorption. The vast majority of tropical orchids may have aerial roots, what are coated with a whitish porous tissue composed of dead cells filled with air. And this fabric, which is called – Velam, like a sponge, absorbs moisture from the air. It also protects the roots from overheating and excessive evaporation. Aerial roots with a special characteristic veil primarily for epiphytic orchids are the best adaptation to the unusual way of life which they lead.
