is otherwise either bright white, or various shades of pink, red, purple or black. The species is further unique in having a dome-shaped synandrium with numerous fertile anthers surrounding a number of central, resiniferous staminodes. Usually the same stamens produce both resin and pollen. The high number of peltate stigmata in the female flowers is also highly distinctive. Finally, fruits are larger than usual for

. The montane forests in the Sambotambo area are situated on the western slopes of the Andes just outside the mouth of the dry valley of Piñas, and are frequently covered by clouds formed by the rise of moisture laden air blowing in from the Pacific Ocean. The new species appears to be endemic to this region that is also home to a variety of other narrowly endemic plant species (

). Given the few existing collections it is difficult to assess its conservation status with certainty, but the apparently limited range and high degree of deforestation in its area of occurrence suggest it might be vulnerable.
