A shrub endemic to Ecuador. Known from a single record in 1934, made south of Quevedo, near La Carmela village, in Los Ríos province. The species has a strong affinity with the widely-distributed P. hispidum, and may represent an extreme phenotype of it. Not confirmed to occur in Ecuador's protected areas network, but may occur in dry forest remnants. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
