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.[1] 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).[2]

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[3] in humid and shady broad-leaved forests,[4] 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.[3][5]

Description

The 5-8 leaves are clear green, lingulate, up to 45 by 4.5–7 cm and thick.[6][1] The 2-7 flowers are 7.5 cm across and open simultaneously on an inflorescence 50–70 cm long. The species has spoon-shaped tips on the long, twisted petals.[1][3] The petals taper from base to apex.[5]

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.[4] The main pollinator is Allograpta robinsoni, a hoverfly.[5]

Uses

Used in China for detoxification and to dispel heat, as a mild tranquiliser, treat febrile rash, pneumonia and depression.[1]
