• Botanical Background: Described by the botanist Sodiro in 1902, and while not widely studied, it has captured the attention of aroid enthusiasts for its distinctiveness in form.

• Geographical Range: Native to the high-altitude cloud forests of Ecuador, it grows at elevations where temperatures are moderate, and the humidity is high.
• Environment: Humid environments with consistent moisture, preferring slightly acidic, well-draining soils; it is adapted to the cooler conditions of its native cloud forest habitat, where it receives filtered sunlight.
