| | | | | stipe: Encyclopedia II - Orchidaceae - Fruits and seeds The orchid ovary is always inferior (located behind the flower), three-carpelate and 1 or 3-partitioned, with parietal placentation (but axile in the Apostasioideae).
If pollination was successful, the sepals and petals decolorize and wilt. But they remain attached to the ovary. The epigynous ovary typically develops into a capsule that is dehiscent by 3 or 6 longitudinal slits, while remaining closed at both ends. The ripening of a capsule can take from 2 to 18 months. The microscopic seeds are very numerous (over a million per capsu ...

| | | | | stipe: Encyclopedia II - Orchidaceae - Leaves They have simple leaves with parallel veins. Their shape is very variable between species, ovate, lanceolate, or orbiculate. Their size and shape can be an aid in identifying the orchid, since it reflects the taxonomic position. The leaves can be enormous or minute, or they can even be lacking (as in the Ghost Orchid Dendrophylax lindenii, a mycoheterotrophic species, and Aphyllorchis and Taeniophyllum, which depend on their roots, which co ...

| | | | | stipe: Encyclopedia II - Orchidaceae - Orchids in commerce One orchid genus, Vanilla, is commercially important, used as a foodstuff flavoring, the source of Vanilla. The underground tubers of terrestrial orchids are ground up and used for cooking, such as in the hot beverage salep or the so-called "fox-testicle ice cream" salepi dondurma. The scent of orchids is frequently used by perfumists (using Gas-liquid chromatography) to identify potential fragrance chemicals. With these exceptions, orchids have virtually no commercial value other than for the enj ...

| | | | | stipe: Encyclopedia II - Kelp forest - Environmental Characteristics Kelp forests are found in temperate ocean waters around the globe wherever water conditions are conducive to the successful establishment of kelp colonies.
Kelp favors waters between about 4 and 20 degrees Celsius; various species of kelp favor different ranges of temperatures, but none grow in waters where the temperature is consistently warmer. Relatively clear water is also necessary, as kelp depends on light for photosynthesis.
Kelp forests are typically found in waters between 1 and 24 meters below the low tide mark; the t ...

| | | | | stipe: Encyclopedia II - Orchidaceae - Reproduction It is in the variety and the very refinement of their reproductive methods that orchids truly amaze. Each time, the lip serves as landing pad for the insects. This labellum has the right color and the right form to attract the right insect. After pollination, the epigynous ovary starts developing and produces a many-seeded capsule.
The Paphiopedilums (Lady Slippers) have a deep pocket that traps visitors, with just one exit. Passage through this exit leads to pollinia being deposited on the insect.
A Eurasian gen ...

| | | | | | stipe: Encyclopedia II - Orchidaceae - Plant thallus and roots All orchids are perennial herbs, lacking any permanent woody structure.
Some orchids are terrestrial, growing rooted in the soil. Terrestrial orchids may be rhizomatous, forming corms or tubers. These act as storage organs for food and water. The root caps of terrestrials are smooth and white. Terrestrials are mostly found in colder climates.
A great many orchids are epiphytes, growing out of soil on tree branches. They occur in warmer regions. Epiphytic orchids have modified aerial roots and, in the older ...

| | | | | stipe: Encyclopedia II - Orchidaceae - Orchid flowers Orchids are truly flowers of superlatives. Even a complete layman in botany is awed by the beauty of orchids. No plant family has as many different flowers as the orchid family.
There are many types of specializations within the Orchidaceae. Best known are the seemingly endless structural variations in the flowers that encourage pollination by particular species of insects, bats, or birds.
Most African orchids are white, while Asian orchids are often multicolored. Some orchids only grow one flower on each stem, others sometimes m ...
