Maxillaria

Finding

This plant matches the description and photos of M. bicentenaria species in the Novataxa paper: "Species New to Science" novataxa.blogspot.com/2021/09/maxillaria-bicentenaria.html. The species is similar to M. pyhalae, but differs in the shape of the lip, callus and a keel-shaped ridge towards the top of the anther. There is an excellent article in Researchgate, "An Homage to Peru's Bicentenary Maxillaria bicentenaria orchidaceae, A New Species previously misidentified as M. pyhalae". This article has excellent photos, drawings and descriptions comparing and contrasting the two species.
