Remarks.

Psammisia is a Neotropic genus of terrestrial or epiphytic shrubs from the Ericaceae family, consisting of ca. 50 species. Its distribution ranges from Costa Rica southward into Bolivia and eastward to French Guiana and Trinidad ( Wilbur and Luteyn 1978; The Plant List 2021). Within the genus, one of the most variable morphologically is Psammisia ramiflora , known only from Costa Rica and Panama. The taxon was described by Klotzsch (1851) based on Warszewicz’s gathering, destroyed during the war. During our studies, we found only one specimen collected by Warszewicz and determined by Klotzsch as P. ramiflora . The specimen is preserved in G herbarium. However, its label slightly differs from both, specified in the protologue and on the type specimen photographed by Macbride (F negative no. 4698). Nevertheless, it constitutes a duplicate of the holotype. In 2006, Luteyn labelled this specimen as the lectotype of the species; however, he did not designate it in publication. Thus, we here propose to designate the specimen preserved in G (https://www.ville-ge.ch/musinfo/bd/cjb/chg/adetail.php?id=238797&base=img&lang=en) as the lectotype of P. ramiflora .
