Mexico: Hildalgo, Lagoon of Metztitlan, 1600 m. alt. Coll. 
Juan Gonzales s.n., sub Nagel 2194! Type! (AMES). 
It differs from D. durangensis (A. & S.) Garay in having 
glandular-pubescent sepals, a differently proportioned lip with a 
different callus at its base and the shape of the rostellum. All 
specimens, with the exception of the holotype collection which I 
have seen named as “Spiranthes durangensis” including those 
from Texas, U.S.A., are all referable to this new species.
