This beautiful plant was discovered in the the Eucadorean 
Andes in the valley of Mindo, at an elevation of 6000 feet, 
by the late Col. Hall, who sent dried specimen to Sir W. 
Hooker that were imperfectly described by Dr. Lindley, and 
it has since been gathered in the same locality by his fellow 
explorer of the Andes, Dr. Jameson, and others. Subse- 
quently, but not till many years after its discovery, it has 
been fully discribed by Prof. Reichenbach in the ‘ Gardeners’ 
Chronicle,’ with two figures, one of the whole plant reduced, 
the other of a portion of a panicle with about fifteen flowers 
of the natural size. As a species its nearest allies are 
O. Hailii and inter-purpureum, both natives of the Andes, 
but it is abundantly distinct from these and all other species. 
Since its importation by the Messrs. Klaboch, 0. cerrhosum 
has flowered with many collectors, amongst the first of whom, 
I believe, is Sir Trevor Laurence, Bart., whose gardener, Mr. 
Spyers, informed Dr. Reichenbach that thirty flowers might 
be produced on a single panicle.
