Finding
The spelling of G. magnicolumna was corrected according to Kew POWO. The lip color is very light compared to most G. magnicolumna species than are shown in the available photos of this species, but can be seen. The lip hairs (trichomes) of this plant, a key characteristic, are identical to G. magnicolumna photos and match the description in the Lindleyana Vol. 10 (1995). The hairs on the underside of the column also match the drawing in the Lindleyana and can be seen back in the throat of the enlarged photos. There are thirteen closely matching photos of G. magnicolumna in the orchidroots.com.
