The late Professor Jameson, of Quito, originally discovered this 

 species on the Ecuadorean Andes near that city, and in 1851 it was 

 gathered by Warscewicz in the same locality. It does not appear to 

 have been introduced into British gardens till 1866, in the autumn of 

 which year a plant was exhibited at one of the Royal Horticultural 

 Society's meetings by Messrs. Backhouse, of York, who had imported 

 it from Ecuador. 



Although scarcely so bright and so elegant as the other species 

 here described, it is well worth a place in every collection of cool 

 orchids.

Lindenia, IV. t. 154. 



A very handsome species discovered many years ago by Dr. Spruce, 

 the German botanist, who explored parts of northern Brazil and 

 Ecuador. He detected it in the last named country on the volcanic 

 mountain of Tunguragua, at an elevation of 10,000 — 11,000 feet 

 growing among the erupted scorice from the crater, a circumstance 

 which suggested the specific name. It was first introduced into 

 British gardens about the year 1872.
