Distribution

This species is abundant in Ecuador and Peru and common in Panama. It is rare in Costa Rica, where the subpopulation occurs mostly in scattered individual plants. Only five or six collections are known from Costa Rica. In Costa Rica it occurs in the Diriá National Park. It can also be found in various protected areas in Ecuador. In some parts of its range, protection is provided due to the emergence of guerrilla warfare and the presence of drug producers, limiting the expansion of tourism, agro-industrial activities, and urban development.
