Cattleya Orchid belong to the Family of Orchids. Some taxonomist recognize as many as 35, 000 species in 1,000 genera. Other taxonomist recognize only about 20,000 species, but even this number ranks the Orchidaceae as the largest family of flowering plants. Cattleya Orchids are perennials, with only one species, Zeuxine strateumatica, known to be annual, They are also typically herbaceous, but some forms may be viny or somewhat woody. Cattleya Orchid root stock may become thickened to form over wintering tubers or pseudobulbs. From early classical time through the Middle Ages, Terrestrial orchids with testiculate tubers were associated human generative processes. In fact, The world orchid is derived from the greek word testicles or orchis.
Orchids are cosmopolitan, being found from arctic the scientific name is Habenaria hypoborea to the tropics and in almost every kind of habitat except desert. Most species of Cattleya Orchids are tropical, and in tropics most orchids are epiphytes means living upon other plants epiphytically but not parasitically. The temperature zone for orchids are mainly terrestrial, growing in soil. Some orchids are saprophytic, living on dead organic matter. Such as leaf mold. A few grow completely underground. Cultivation of orchis is an important worldwide industry. Thousands of hybrids have been created.
Most orchids have small flowers, some as tiny as 3 mm, as in Pleurothalis. Others have large, broad-petaled flowers up to 23 cm or 9 inches across. As in Catlleya, or long, threadlike petals that may span 60 cm (2ft) from the tip to tip, as in Brassia. Orchid flowers maybe bisexual or unisexual, they demonstrate a wide range of complexity that involves modification for attracting or admitting only specific pollinators, such as butterflies or bees. Only about 200 species of orchids known to be air or water pollinated.
The wild orchid flower's floral enveloped consist of an outer whorl of three, usually equal sized, petal like sepals and an inner whorl of three petals, two of which resemble the sepals. The third petal, called the lip or labellum, may be highly modified. The lip is in the upper position in the bud, but in most orchids it is eventually positioned in the lower part of the flower, a process called resupination.
The seed bearing, or female, organ of the flower is the pistil. The top of the pistil, called stigma, is three lobed orchids and serves as the deposition site for pollen. In most orchid partsof one of the three lobes is modified into a structure called rostellum. Used in transferring pollen from the anthers of the pollinating insect of the agent.
The male organ of the Catlleya Orchids flower is the stamen. Which possesses a pollen producing head called the anther. A distinctive feature of the orchid flower is the fusion of the male stamen with the pistel into a single unit or column.
