Lepanthes valerieae is most similar to L. silverstonei Luer, but it differs in the narrowly-elliptic to narrowly ovate leaves, < 1 cm wide, the filiform up-per lobe of the petals surpassing the dorsal sepal length and the rudimentary ovate, sub-triangular lower lobe, and the triangular, concave appendix with a subcylin-dric, retuse almost glabrous apex. It is also similar to L. antennata Luer & Escobar; however, it is distinguished by the long apical lobes of petals, surpassing the dorsal sepal, the longer connectives > 18 mm, rounded lobes of the lip, and the oblong, flattened appendix
