gradually swells, and becomes a green pseudobulb, of an 

 ovate or oblong figure. The scape is radical, and a foot 

 and a half or two feet high, sometimes bearing as many as 

 G or 8 flowers expanded at once. They are less perish- 

 able than those of many of the Orchis tribe; their sepals 

 and petals are greenish, spotted with irregular blotches of 

 brownish purple ; the labellum is a bright blue, deeply 

 stained with darker lines, and has at its base a remarkable 

 fleshy, elevated, lunate, transverse ridge. 



Eulophia is readily known among the genera most 

 nearly allied to it, by its ascending sepals and crested cal- 

 carate labellum : the crest is seen under various forms, 

 sometimes as a few elevated lines, sometimes as a number 

 of thick ridges, or, as in the present case, in the form of a 

 thick transverse hump. The length of the spur is very 

 variable. 



Our drawing was made in the Garden of the Horticul- 

 tural Society in November 1828.
