According to Dr. Reichenbach, this belongs to Lindley’s 
section Myanthium of Odontoglossum, characterized by the 
sessile lip, clawed sepals, and comparatively small flowers, 
which are further described as having parallel lateral 
sepals, which project considerably below and beyond the lip, 
giving the flower a peculiarly irregular appearance. This 
latter character I do not find to be possessed by O. Edwardi, 
which rather falls into the section [santhiwm, with radiating 
subequal sepals, producing singularly regular flowers. 0. 
Edwardi is a native of Ecuador, where it was discovered by 
Edward Klaboch, whom Dr. Reichenbach describes as an 
energetic collector. The specimen here figured flowered in 
the Royal Gardens in April of the present year.
