Gerardoa (jer-ARD-doh-ah) is a unidpecific genus that contains one species that used to belong to Pleurothallis.  The plant is similar to Sarcinula fulgens, but differs in the elongated petiole of the large, broadly elliptical leaf, and a very short peduncle that bears a successive and distantly two-flowered raceme.  The flowers of the two species are of similar orange color and size, but in Gerardoa montezumae, the sepals are tall-carinate and apiculate.  The lateral sepals are semiconnate and concave below the middle and without lateral lobes.  Most curious is the column-foot that is concave between a pair of calli as seen in some species of Zootrophion and the ovary is undulate-crested as well.
