This species is know only from one small mountain, Cerro Campana, on the coast of Department La Libertad, Peru.

Note the larger diameter of the stigmas in the photo above compared to photos below taken in the same population but at a different time. In general, in Jaltomata, male-sterile looking plants have fat stigmas and normal hermaphroditic flowers have noticably smaller stigmas; I can't tell if this is what is going on in the photo above because I don't have flowers (I have only this photo of this collection). Photo by Segundo Leiva G., October 2008.

Fewer than 40 plants of this species exist, all on one small mountain.

Soil pH 6.7 at plants (measured late August 2007, associated with plant collection Mione, Leiva & Zapata 759)
