A shrub endemic to the western slopes of the Ecuadorean Andes, where six subpopulations are distributed from El Oro in the south to Pichincha in the north. The only record in Ecuador’s protected areas network is a nineteenth century collection close to Pululahua. Additional subpopulations may occur in the Los Ilinizas and Cotacachi-Cayapas protected areas. According to C. Taylor (in Andersson et al. 1999) the species is easily mistaken for the endemic P. calothyrsus. Apart from habitat destruction, no specific threats are known.
