Geographic Distribution: J. cajamarca is distributed in northern Peru, mostly Department Cajamarca, but also in northern department La Libertad. Its habitat is roadsides and hillsides with shrubs between 1,500 and about 2,600 meters of elevation. See table of specimens studied (below) for more information.

Figure 4. Longitudinal view of flower of Jaltomata cajamarca. This flower looks like it is hermaphroditic, unlike those in figure 5 (the same population). Stigmas are smaller on hermaphroditic flowers. To notice this, consider stigma width (diameter) in this photo as a fraction of corolla tube diameter, and then compare stigma width (diameter) as a fraction of corolla tube diameter in the male-sterile flowers in figure 5. Note how the tube of the corolla is slightly broader at the base than at the throat (photo by Mione, Mione et al. 793).

Figure 5. Jaltomata cajamarca. These flowers appear to be male-sterile, having malformed or abortive anthers. Broader (larger) stigmas are present on flowers having abortive anthers! (Peru, Department La Libertad, province Otuzco, near Huaranchal, photo taken in Peru by T. Mione, Mione et al. 793).

Figure 6. Jaltomata cajamarca. This plant was grown from seeds in fruits of a plant of the same population as shown in figures 4 and 5. In contrast with the plants we saw in the field, the stamens of this plant appear to have developed normally, the stigma is much smaller and the style is much longer (photo by T. Mione at CCSU).

The Huaranchal population was discovered by Segundo Leiva G. in Peru, La Libertad, a few km before Huaranchal, years before we visited it together in May of 2008.

Figure 11. Fruit (units along bottom are mm, Mione et al. 757).	Figure 12. Note shape variation among leaves: entire and repand-toothed leaves showing, and a toothed leaf is shown in the last photo of this grouping of photos (Photo by Segundo Leiva G., Leiva et al. 4445 = Mione et al 793)

Geographic and Altitudinal Distribution: Peru.

The fruits are eaten (Sagástegui 10315, 12546, 13050, 14121) and the local name is "canamuela" (Sagástegui 10315, 12546, 13050, 14121).

I thank Segundo Leiva G. for bringing me to populations of this species during our field work together.
