The flowering specimen of this rare Orchidaceous plant was 

 sent to us in January of the present year by our excellent friend 

 Mr. Bateman, from his collection at Biddulph Grange, Congle- 

 ton. It is a native of New Granada, and was discovered m 

 the Pamplona, at the height of 8500 feet above the level of 

 the sea, by Mr. Schlim, and has been hitherto only known 

 by the description given by Dr. Lindley in his valuable ' Folia 

 Orchidacea.' It is there recognized as a new genus, " differing 

 from Brassia in some important particulars : — 1, the lamellae of 

 the lip are confluent and membranaceous ; 2, the lip is parallel 

 with the column, and solidly united to the base of it ; 3, the 

 column is twice as long as in other Brassias, and thin-edged at 

 the base ; 4, the caudicle is short and obovate while the gland 

 is circular." It flowered with Mr. Bateman in January, 1864. 



Descr. Epiphytal. Pseudobulbs about four inches long, sub- 

 cylindrical, tapering upwards, bearing one to three broad linear
