Brazil. Organ Wountains, where it was discovered by Mr. Gardner in 1837, and 

 whence it was sent hy ihc same zealous collector to his distinguished patron, his 

 Grace the Duke of Bedford at Woburn-Abbey, Kamed in conpliment of ihe ablc Hor- 

 ticulturist, who is in charge of ihat noble collection. 



Among the dried specimens there is only one of this species and that is marked 

 „very rare" and is numbered 442 of the Organ Mount. CoII. In the Siove of 

 Woburn it bloss. Oct. 38. 



As a species it comes near 0. crispum B. M. t. 3499 , but the panicle is nuicli 

 larger bcaring more copious flowers ; ihese flowers are very dilTerently coloured 

 and marked: ihe crest and side lobes , arid slill morc ihe column present also amply 

 sufficient characters of distinction , ihe latier being considerably smaller, with very 

 short, angled , by no means serrated wings,

Brazil. ~ For a si>eciraen I am indebted to James W. Buller Esq. of Downes 



near Exeter, wbo observes that it resembles 0. crispum more ihan any of thc spe- 



cies he has seen, but is much more beautiful, having petals gaily edged wilh briglit 



yellow, and some of ihe sepals barred with ihe same colour, jThe plant has a large 



panicle and very gay appearance. I must however add, that 1 find the ground colour 



of ihe flowers very much browner, ihan in the figure in the Bot. Mag. in my copy, of 



which it is britk rcd. The bidenlation of the wings of the column is a variable 



circumstance, but ilie appendagcs of the base of the lip are constantly as represented 



and described by Sir Wm. Hookcr.
