Several biogeographically interesting species have been recorded in the region, such the Colombian endemic genus of Fagaceae , Colombobalanus (Lozano, Hern. Cam. & Henao, Jesús Eugenio) Nixon & Crepet , only known from three other localities in Colombia ( Aguirre-Acosta & Botero-Echeverri 2018), as well as the endemic species: Arthrostylidium virolinense Londoño & L.G. Clark , Eugenia fernandez-alonsoi Parra-Os., and Magnolia virolinensis (Lozano) Govaerts.

Common names:― Vinagrera (in Spanish), because the stems taste of vinegar (Agudelo 170).
