central callus

The sidelobes of the labellum (lip) come together in a central callus.

Leptotes vellozicola is the only easily recognizable species in this group as it has a thick central callus next to the apex of the lip petal.

The colour is yellowish or pinkish, radiately streaked with chestnut brown or red above, the base with a reddish or purple zone around the central callus, the outer part white, more or less striped radiately.
