Apparently, the Peruvian Sobralia candida (Poepp. 
& Endl.) Rehb.f. is the only species in the genus with 
which this new taxon might be confused. Vegetatively 
these two species are very similar, though iS. /ancea pos- 
sesses longer and more acuminate leaves. In the floral 
structures, however, a number of discrepancies can be 
observed: the sepals and petals are acute in S. candida 
and acuminate in SS. /ancea; in the former the lip is 3- 
lobed, with the apical lobe wider than the lateral ones; 
in the latter the lip is pandurate, and the apical portion is 
much narrower than the basal part. In addition to these 
differences, S. candida is described as having ‘‘snow- 
white’? flowers, while the color of S. /ancea is canary- 
yellow with purple lamellae on the lip.
