Danton, Philippe/Perrier, Christophe/Martinez Reyes, Guido (2006) (pp. 485, 531, 554)
Voucher cited: Danton I(5/123)1488. "Esta liana vigorosa se encuentra en varios sitos del pueblo de San Juan Bautista, algunas veces está fuera de los lugares cultivados. Esta especie cubre el suelo de un tapís denso de hojas, en sotobosque y trepa a lo largo de los troncos de los árboles. Con el tiempo, esta liana logra ahogar su soporte. Es una evidencia que la penetración de esta especie en la mirtisilva fernandeziana seria como la llegada de un enemigo más, tal vez tan temible como la zarzamora, aúnque sin espinas".
