Kefersteinia taggesellii Neudecker, Orquideología 19 (3): 98. 1994.

Kefersteinia taggesellii is superfcially similar to K. graminea (Lindl.) Rchb. f. and K. tolimensis Schltr. but the latter species belong to a distinct group, characterized by a low, broad, laminar callus. Among the species provided with a umbonate callus, K. taggesellii is more closely reltaed to K. taurina Rchb. f., from which can be distinguished by the presence of much prominent wings
on the column (vs. reduced), and the quadrate, doubly bifurcate callus (vs. bull head-shaped, with two diverging horns at the base).
