Neotropical <i>Poteranthera</i> (Melastomataceae: Microlicieae) Revisited

Trembleya warmingii is transferred to Poteranthera based on its herbaceous habit, elongate internodes, spreading gland-tipped trichomes on foliar margins, and floral morphology. A revised description of P. warmingii is provided along with an illustration based on the type, a diagnostic key, a distribution map of the five currently recognized species in Poteranthera, an updated circumscription of Poteranthera, and comments on its generic delimitation.
