. Due to their popularity, Paphiopedilums have been ruthlessly gathered and poached from the wild, making them very rare or extinct there. As soon as a new species or population is discovered, poachers will take the plants for orchid collectors who pay large sums of money. Habitat destruction is an additional factor contributing to their rarity.

Each new shoot only blooms once when it is fully grown, producing a raceme between the fleshy, succulent leaves. The roots are thick and fleshy. Potted plants form a tight lump of roots that, when untangled, can be up to 1 m long. Members of this genus are considered highly collectible by orchid fanciers due to the curious and unusual form of their flowers. Along with ''

(including those of closely related '' Phragmipedium'' slipper orchids), ''Paphiopedilum'' stomata do not. This difference results in simpler, but weaker control of stomatal function. For example, most plants close their stomata in response to either blue or red light, but ''Paphiopedilum'' guard cells only respond to blue light. The fact that they lack chloroplasts has made them valuable to researchers investigating stomatal function. For example, it enabled the discovery of intracellular events that precede stomatal closure.

In horticulture

The paphiopedilums are among the most widely cultivated and hybridized of orchid genera. Spectacular new species are being discovered every now and then; for example the golden slipper orchid (''P. armeniacum''), discovered in 1979 and described in 1982, amazed growers of orchids by the extraordinary beauty of its golden flowers. In addition, growers have bred thousands of interspecific hybrids and registered them with the

''Paphiopedilums'' are terrestrial and evergreen in growth habit, and by careful selection of species and hybrids, it is possible to have a flowering period extending over nine months of the year.
