First cultivated in 1830 by Dean Herbert, who had received plants 

 from Brazil, one of which he presented to Earl Fitzwilliam, in whose 

 collection at Went worth Woodhouse it flowered in perfection in 1835, 

 and was then figured in the Botanical Magazine. It was subsequently 

 gathered by Miers near Rio de Janeiro, by Gardner on the Serra do 

 Mar, by Weir in 1861 — 2 in the province of San Paulo while collecting 

 for the Royal Horticultural Society of London, and it has since 

 been occasionally very sparingly imported with other orchids from 

 these localities. The specific name, "horn-bearing," refers to the 

 basal lobes of the labellum. 



On, crispum. 



Pseudo-bulbs oblong, compressed, 3 — 4 inches long, brownish ribbed and 



furrowed on the flattened side, di-triphyllous, Leaves oblong-lanceolatej 



6 — 8 inches long, 1 — 2 inches broad. Scapes 30 — 45 inches long,

The early history of this superb species is thus briefly sketched 

 by Dr. Lindley : — 



" The first notice I had of the existence of this species was the finding 

 in the Herbarium of Sir William Hooker, a drawing and one single dried 

 flower of it which had been sent from the Organ Mountains in 

 Brazil, with a memorandum that from fifty to sixty flowers frequently
