late, deciduous hracts, as long as the peduncle. Each/ow^ is about four inches across 

 if fully expanded, with pale-green sepals ^nd petals, and a singularly warted /?>, marked 

 with deep broad black veins and stains upon a greenish-yellow ground. The crests are 

 two, deep, double-warted lines, on each side of a three-ribbed, central discj these crests 

 converge towards the middle of the lip, where they lose themselves in a field of paUid 

 rugged, irregularly situated, often two-lobed warts. The column is green, slightly ex' 

 panded into thin, rounded edges. The lip, although really oblong, yet, in consequence 

 of the manner in which the sides are bent down, has much the form of a violin
