The original discoverer of this plant was Dr. Griffith!, who 
observed it in the Khasia Hills, growing on trees of Gordonia, 
on the descent of the Suniassee Valley. It was also found there 
later by T. Lobb! The plant appeared in October, 1856, in the 
garden of Messrs. Loddiges, when Dr. Lindley brought home, 
during one of my London stays, such a miserable specimen, 
which he was good enough to accept for naming: a single flower 
from the Loddigesian collection; it came in the Schillerian 
collection, where it grew well and flowered in profusion. At 
length, in October, 1866, it appeared in the collection of Messrs. 
Rollissons, of Tooting. They have, however, stated that their 
collector had named it a Celogyne from Java. It may have been 
obtained at Boitenzorg Gardens, where they could have got it 
from the Calcutta Gardens. Finally, I obtained it, in 1869, from 
Director Linden of Brussels.
