Paphiopedilum parishii is a species of orchid found in northern and western Thailand, Laos, Myanmar, Yunnan and Assam, in montane forests at 1200–2200 m above sea level.[2] It is named after Charles Samuel Pollock Parish, an English botanist and avid plant collector who had a particular interest in the flora of Myanmar (then Burma).[3]

Plants in this species are described as being epiphytes or lithophytes. They grow in thick moss which occurs on boulders or on the tree branches of Terminalia[4] in humid and shady broad-leaved forests,[5] making them facultative lithophytes.
Paphiopedilum parishii is placed in section Pardalopetalum based on its chromosome count, multifloral inflorescence, distribution and leopard spots on the petals.[4][6]

Description
The 5–8 leaves are clear green, lingulate, up to 45 by 4.5–7 cm and thick.[7][2] The 2–7 flowers are 7.5 cm (3.0 in) across and open simultaneously on an inflorescence 50–70 cm (20–28 in) long. The species has spoon-shaped tips on the long, twisted petals.[2][4] The petals taper from base to apex.[6]
Reproduction
Paphiopedilum parishii is unique in that it evolved a specialised self-pollination mechanism as a possible adaptation to the insect-scarce habitat. The pollen grains and anther liquify and move from the apex of the filament to the stigma.[5] The main pollinator is Allograpta robinsoni, a hoverfly.[6]
Alternative medicine
The plant is used in traditional Chinese medicine for detoxification and to dispel heat, as a mild tranquiliser, to treat febrile rash, pneumonia and depression.[2]
