It seems ihat this originally flowered in Germany wilh Counl Aremberg : but Jt 

 Iiad been lost sight ol uniil my friend the Chevalier Pinel re-discovered it. The 

 fiowers are dirty-white, in a small diffuse panicle , stained nnd spotted with purple, 

 the column-wings are nlso purple. It is so like the last as lo be easily mistaken 

 for it, but, instead of a double fringe of leeth , the lip bears a pair of subulate re- 

 curved horns for ;he crest. 



Wild in Brazil; on tlie summit of the Serra Morroqueimado, nowhere except upon 

 cleared land where new sorts of ligneous planis have made their appearance— Pinel.

I have now seen a dried spccimen of ihis in ihe Hookcrian Ilerbarium , bul il 

 adds lillle to the information formerly afTorded by the drawing. The oval pseudo- 

 bulbs bear ihree leaves. The scape is spoited wilh purple, straight for len or eleven 

 inches, when it becoraes a iwining raceme, of which about len inches bcaring flowers 

 are present in the plant before me, The sepals are linear, retuse, white; the petals 

 broad, obovate , violet bordered with white . the lip of ihe same colour, concave, 

 streaked wilh crimson , baving four collateral sharp-poinled lamellae. The anther 

 riowny; coluran furnished with iwo great acinaciform ears, terele at the base', wiih 

 a pair of vcrtical quadrangular valve-Iike plaies just below ihe sligma. No olher 

 species is much like ihis.
