A tree endemic to Ecuador, where it is known from multiple collections made on the southern slopes of the Volcán Sumaco, along the Hollin-Loreto road, during 1988–1989. Also collected in 1988 in the poorly explored Parque Nacional Llangantes, and in 1989 in Mera. Another population was registered on the border of Tungurahua and Pastaza provinces in 1933 by L. Diels near the junction of the Pastaza and Negro rivers. Reportedly also collected in Carchi province, but details are not known. There are isolated reports from the wet coastal forest, in the Río Palenque private reserve and in the San Sebastián area of the Parque Nacional Machalilla; these need to be confirmed. Apart from habitat destruction, no specific threats are known.
