Comparison With Department Lima: The department of Lima borders the department of Ancash on Ancash's south side. Both Lima and Ancash have seven species. Two of the species are shared (J. andersonii & J. bicolor). Only one specimen of J. andersonii has been collected in the department of Ancash. Regarding J. bicolor, in Ancash the corolla is green (as shown above) and in department Lima the corolla is purple. If these actually represent different species then the plants from Ancash will get a new name. If J. bicolor is split in this manner, then we will report that only one Jaltomata species is shared in the departments of Lima and Ancash. With the current taxonomy, two of Lima's seven species are shared with Ancash, and two of Ancash's seven species are shared with the department of Lima.

Red-Orange Nectar: In the Department of Ancash only J. weberbaueri produces red-orange nectar. Click here for a table of Jaltomata species having red to orange nectar.

Islands: One of these species (J. lomana) may be viewed as growing on a virtual island (lomas). Two additional Jaltomata species grow on oceanic islands, J. antillana (Greater Antilles) and J. werffii (Galápagos Islands).
