 Distribution and habitat: ―The forests where this variety grows are dominated by Quercus humboldtii (Fagaceae), accompanied by highly diverse families such as Rubiaceae, Melastomataceae and Lauraceae and genera Miconia, Anthurium and Psychotria (Reina et al. 2010). 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).
