A member of the section Spathium, and apparently most allied

3 2 -41⁄4 in. broad; petioles 9-10 in. long. Scape 14 in. high, few- 
wered. Bracts ovate-oblong, subobtuse, 3-4lin.long.  Pedicels 
: Tin. long. Dorsal sepal broadly oblanceolate, acute, 7 lin. long;

Yungas, 1890 (609). 
Allied to the Peruvian G. tingens, Poepp. & Endl., but the lip 
scarcely half the size, in which respect it approaches G. Gardner: 
Hook., though the lip is not nearly so membranaceous.
