The native country of this species seems not to be 

 exactly known ; it was first published by Dr. Reich enbach 

 from specimens that flowered in the famous Orchid Col- 

 lection of Consul Schiller at Hamburg; and a few years 

 later, in the " Xenia Orchidacea," it is mentioned as to be 

 found in various gardens in Germany. It is, however, 

 supposed to have come from St. Catherine's in South 

 Brazil. The specimen here figured was contributed by 

 Messrs. Sanders, of St. Albans, in 1886, and flowered in 

 August of this year. 



Dbsce. Pseudo-bulbs sub-distichously imbricate on a 

 short rhizome, an inch long, broadly ovoid, compressed, 

 truncate, smooth, in age with a few broad shallow grooves 

 on each face. Leaves two at the top of the pseudo-bulb, 

 sessile, four to six inches long, linear-oblong, rounded at 

 the tip, thickly coriaceous, deep green and shining, chan- 

 nelled down the middle. Raceme eight to ten inches long, 

 long-peduncled, rather stout, flexuous, pendulous; bracts 

 small, ovate, appressed to the pedicels. Flowers one and a 

 half inch across the petals. Sepals linear-oblong, acuminate,
