Csticealum; rtepalis lanecolatis patcntibus dorsali potnlisque fornicatis, labello 

 suhroliiutlo abrupt^ acuminate fimbriate medio saccalo: ostio coutracto rcni- 

 fbrmi postlce dentate, columns cirrhatfi. Lindley in Botanical Register,

This specie* is one of the handsomest of the lingular genu* to which it belongs ilie colour* of 

 its large flowers being much brighter than is usual nmnnu tin* race. For if* introduction to this 

 country we arc indebted to lite Messnt- Loddi^cs, who procured it from British Guavami. 



In FOLUGB it is so little different from others that it cannot he distinguished by any describahh* 

 marks. The flower-stems an* from a foot to fifteen incite* high, and each War* seven or eiHit 

 Hovers full four incite* in diameter ; at first they grow erect, hut toward* the point tliey bend down 

 gracefully, a* if beneath the weight of the flower*. The skimls arc lanceolate* c^ual. spreading, 

 inside deep purple, spotted with yellow, outside tinged with yellow. The petal* arc of the same 

 form am) nearly the same size, but are thinner in texture, more spotted with yellow* and at first form 

 an arch over the column, but, after the flower has l»ccn for some time expanded, they spread back 

 even more titan the dorsal sepal. The lip i* of a most irregular form, and rich yellow, fhicklv 

 sprinkled with crimson dot*; in form it i* roundish ovate, with a contraction on each side, and a 

 gradual tapering to the point; all round it is bordered by long firm fringe*; in the middle is a 

 callous perforation, kidney -shaped in front, slightly twoJobed and wartcd at the back ; this perfora- 

 tion opens into a small bag shape*! chamber, which project* below the underside of the lip. At first 

 the lip fa ilat; but it soon turn* back at the point, so that at last it is bent iu the middle at almost a 

 right angle, ami hides the conical chamber already described.
