Although we have been unable to obtain specimens of Pleurothallis gomesii-ferreirae for inclusion in our phylogenetic analyses, we do not hesitate to add this taxon to our list of Madisonia species. The tiny plants possess an elongate, articulate rhizome, which is ca. 1 cm long between ramicauls; the leaf is erect, linear-lanceolate, 1–1.5 cm long; the inflorescence is erect, ca. 3 cm long; the flower is minute and patent; the sepals are ca. 5 mm long, the lateral sepals almost entirely connate to near the apex to form a synsepal; the lip is oblong, trilobed, rounded and obtuse, with lateral lobes erect and placed slightly above the middle of the lip.
