Discussion. Jaltomata lanata lacks gland-tipped hairs, has a corolla limb 7--11 mm across, stamens 3.1--4.2 mm long, and the style is 3--4 mm long. In contrast, the species to which it is most similar, J. hunzikeri Mione of Peru (Department Lima), is villous with gland-tipped hairs, the corolla limb is 16--17 mm across, stamens are 4.8--7 mm long, and the style is 6--7.7 mm long. Distribution, ecology, etymology, uses. Jaltomata lanata grows in Peru, Department Cajamarca, province San Pablo, between 1850 and 2400 m of elevation, on roadsides and the edges of agricultural fields. Flowering is in April, May and June, and fruits were observed in May and June. The specific epithet refers to the lanate young plant axes. |

The ripe berries have an agreeable flavor and are consumed by people (Leiva, 1998).
