 flowers ; the pseudobulbs are ovate, with a pair of oblong lance-shaped leaves, 

 and the flowers, which grow in elongated racemes on radical scapes, are over 

 4 inches across, the sepals lanceolate acuminate, white with a few oblong pale 

 purplish spots ; the petals rather broader but acuminate and of a pure white ; 

 and the lip oblong blunt denticulate, with a pale yellow stain over the disk 

 and a few spots of a rather darker purple ; all the parts, the lip especially, 

 being undulated at the edge. — JSfew Grenada.
