The fascination with orchids goes back centuries. The Victorians, for example, sent expeditions all over the world in search of new species to entertain wealthy collectors.
Today, many orchids are still highly sought after due to their large blooms, fragrance and rarity.
Here is a look at some of the orchids that were collected and sold illegally at the markets in Thailand.
(The Excluded Lady Slipper Orchid)
It is known to exist only within a 4 sq km area of limestone forest in Peninsular Thailand. It is recognised by the International Union for Conservation of Nature as critically endangered and is protected in Thailand.

(The Longan Tree Dendrobium)
It is found only in northern Laos, although scientists are still uncertain about exactly where it can be found in the wild. The species was first found growing in a greenhouse in Thailand, where it had been illegally imported.
It has not been studied well enough to determine its conservation status, but it is likely threatened because of its presumed narrow distribution, and the pressures of habitat destruction and illegal commercial trade.
(The Elephant Freckle Orchid)
An attractive, fragrant orchid that can be found across tropical Asia.
Although heavily collected from the wild, the species is also legally grown in greenhouses across Thailand.
(The Moon Chiloschista)
This leafless orchid has very small flowers less than 1.5cm in width. This species exemplifies the diversity of the orchid family, as well as some consumers' interest in small, less commonly traded species.
Commercial trade in such species can also be a threat to their conservation, as they are collected in huge volumes.
The conservation status of the Moon Chiloschista, however, has not yet been studied.
