O. EXCELLENS, Bclib. /.—This ' wonderfully fine ' plant is thought to be a 

 natural hybrid between 0. Pescatorei and U. tripvdians. The flowers are rather 

 broader than those of the latter ; the sepals yellow with a few purple blotches, 

 the dorsal one white in the centre ; the petals much broader, white, having 

 yellow margins ; and the lip pandurate, emarginate, apiculale, white, having 

 numerous small purple blotches on the sides and a few larger purple blotches 

 on the front ; the crests are yellow, and consist of two long divaricate keels, 

 one on each side of a central line, the keels having one tooth at the back and 

 another at the end, while on each side stands a series of curved teeth. It flowers 

 during the summer months. — New Grenada.

 across, fragrant ; the sepals slightly under, and the petals over f inch wide, the 

 former appearing narrower by turning back when mature, and the latter remaining 

 flat ; sepals and petals white at the base, rich yellow towards the tips, their entire 

 surface, except the tips and a narrow margin, spotted and banded with purplish- 

 brown, the markings being in smaller spots near the column, and increasing in 

 size on the outer portions of the segments ; lip irregularly ovate, slightly pandu- 

 rate, toothed at the margin, white tinged with yellow down the middle, and with 

 several rich brown blotches round the crest, and some smaller spots at the sides 

 of the basal portion of the lip. Flowered in the garden of Baron Sir J. H. W.
