Orchids: Flowers
built 221 days ago
Orchids, like tulips, have become a major market throughout the world. Buyers now bid hundreds of dollars on new hybrids or improved ones. Because of their apparent ease in hybridization, they are now becoming one of the most popular cut-flowers on the market.

Orchids have developed highly specialized pollination systems and ... the chances of being pollinated are often scarce. This is why orchid flowers usually remain receptive for very long periods and why most orchids deliver pollen in a single mass: each time pollination succeeds thousands of ovules can be fertilized.

If roses are the flower of romance, then orchids are the flower of passion. Collectors through the years have risked life, limb, and incarceration in their quest for yet another rare orchid to add to their hoard. They've often died in the effort--usually by accident or disease, but sometimes as a result of murder by headhunters or even a rival orchid collector! There have even been cases of "death by orchid." Borneo's Grammatophyllum orchids can grow to a circumference of 40 feet (17 meters) and weigh more than half a ton (tonne). These have been the death of more than one collector who was crushed when trying to dislodge one from the top of a rain forest tree.

All orchids belong to the Orchid Family, Orchidaceae (or-Kid-ACE-ee-ee). Orchids are divided into two basic growth types: monopodial and sympodial. Monopodial orchids have a central stem which grows continuously from the tip. Flowers are produced from the stem between the leaves, usually alternately from side to side. Phalaenopsis orchids are a good example. Sympodial orchids, such as cattleyas, laelias and paphiopedilums, possess a rhizome which sends out a shoot.

All of the other orchids, the clade called Monandria, retain only the central stamen, the others being reduced to staminodes (4). The filaments of the stamens are always adnate (fused) to the style to form cylindrical structure called the gynostemium or column (2). In the primitive Apostasioideae this fusion is only partial, in the Vanilloideae it is more deep, while in Orchidoideae and Epidendroideae it is total. The stigma (9) is very asymmetrical as all of its lobes are bent towards the centre of the flower and lay on the bottom of the column.
