Most Poorly Known Floristic Regions

Certainly among the richest areas on earth for Araceae are the Chocoan lowlands in northeastern Colombia and the western slopes of the Cordillera Occidental. Certain small parts of this area have been reasonably well collected and other portions such as the Pacific slope of Cauca Department have scarcely been touched. The flora seems to be largely endemic and the number of undescribed species in the flora is astonishing. Other regions which are still poorly known are the western slopes of the Cordillera Oriente in Colombia, eastern and western slopes of the Ecuadorian Andes, especially in the northern part of the country, the eastern slopes of the Andes in southern Peru, especially in Zamora-Chinchipe and far northern Peru, especially in the Department of Amazonas. All species in these areas are likely to be poorly known.
