Paphiopedilum sanderianum

Paphiopedilum sanderianum is a rare species of orchid endemic to northwestern Borneo (Gunung Mulu). First discovered in 1885 by F. Sander's collector, J. Foerstermann, the orchid became renowned for the remarkable length of its petals, which can measure over 1 m long. The largest in recent times was one grown in 1999 by Dr. John M. Doherty with petals 90 cm long. Although P. sanderianum has been used as a parent in a number of crosses, none of the resulting hybrids have so far matched the extraordinary lengths of this species' petals. However, soon after the turn of the 20th century, this rare orchid was lost to cultivation and thought to be extinct in the wild, until its rediscovery in 1978 by Ivan Nielson. The wild population of Paphiopedilum sanderianum grows protected in Gunung Mulu National Park....read more on Wikipedia.
