long, spur cylindrical compressed, constricted in the middle, 

 inflated at the apex, 4 mill, long ; petals included within the 

 galea supine oblong-falcate acuminate, ascending at the apex, 

 toothed at base, 4-5 mill, long ; lip linear or linear-lanceolate 

 spreading-decurved, 5-6 mill, long; rostellum very short, scarcely 

 rising above the stigma ; anther reflexed, somewhat pendulous. 



Described from several living and dried specimens, including 

 Drege's types ; the drawing from a pLant gathered near Ceres. 

 Colour of the flowers white with a greenish yellow patch on each 

 side of the odd sepal down to the end of the spur, also on each 

 side of the side se^jals, a purple stripe on the lip and on the edges 

 of the petals. A variable species as to the length and thickness 

 of the spur, and the amount of pubescence on the sepals and lip. 

 A very distinct species, not easily to be mistaken for any other.
