Discussion
Maxillaria parviflora flowers in September in Florida and in November in Central America.
The Florida occurrence is based on a collection by Roger Hammer from a single host tree; other unconfirmed sightings have been made. The several large plants reported by Hammer, the occurrence in Cuba, and the presence of other widespread tropical species locally leaves little doubt of the identity and presence of this outlier in the flora.
The types of Scaphyglottis parviflora and Ornithidium confertum agree well with the Florida plant often recognized as Maxillaria conferta.
