Common Name Wallis' Schomburgkia
Flower Size 1 1/2" [3.75 cm]
Found in Venezuela, Colombia and Napo province of Ecuador as a large sized, warm to cool growing epiphyte with fusiform, rugose with age pseudobulbs carrying 2, coriaceous, oblong-elliptic, heavily creased leaves and blooms on a terminal, racemose, 16" [40 cm] long, several to many [6 to 12] flowered inflorescence arising in the spring on a mature inflorescence.
There is quite a bit of color variation in the species and they can be much browner in color than the photographed flower.
This species is closely related to S lueddemanniana with the main difference is that S wallisi is from South America and S lueddemaniana is from Central America but I have seen both species and have noticed that S wallisi has a small yellow spot with a yellow hook at the apex of the lip and S lueddemaniana is has a larger, yellow, apical spot and no apical hook. From Schomburgkia undulata it differs in the lip ornamentation.
