Shrub or suffrutescent, 0.80--1.2 m high; young axes angulate, green or brown, sericeous to lanate; woody stems brown, somewhat angular, to 1.5 cm in diameter at base, sparsely pubescent to glabrate. Leaves alternate, distally geminate, the blade ovate or eliptic, to 12.5 X 8 cm, membranous, both faces glabrescent or pilose with both finger and branchlet hairs, the apex acute, the base rounded, the margin dentate to entire; petiole to 3 cm. Inflorescence axillary, 4- to 8-(13) flowered including buds; peduncle and pedicel both 4--7 mm long, terete, green and lanate with both finger and branchlet hairs. Calyx green and broadly crateriform during anthesis, 7--8 mm across, the lobes deltoid, abaxially densely villous with branchlet and finger hairs, adaxially glabrous except for glands; at fruit maturity green and to 10 mm across; corolla short-tubular with a 5-lobed, rotate limb, whitish purple to pale purple, the tube (obscured by pressing) 2.4 long X 3.4--3.8 mm wide, within the tube two dark-green maculae flank the radial vein extending to the tip of each corolla lobe, narrow purple ring at mouth of tube, the limb lacking lobules, 7--11 mm across, adaxially glabrous, abaxially sparsely pubescent with finger, forked and branchlet hairs, the margin ciliate; stamens 3.1--4.2 mm; filaments somewhat purple at base, otherwise off-white, pubescent with unpigmented hairs along 40--50% of the length; anthers yellow, 1.3--1.5 mm, exserted beyond mouth of corolla to 1 mm; style 3--4 mm, off-white; stigma capitate, bilobed, green, 0.45—0.75 mm, exserted beyond anthers 1.5 mm; gynoecium glabrous except for stigma papillae 30--35 µm long; disk broad, girdling base of ovary. Berries subspherical, orange, to 7 X 9 mm at maturity; seeds 14 to 21 per berry, brown, alveolate, sub-reniform to sub-triangular, 1.5--1.59 X 1.2--1.29 X 0.45--0.48 mm.

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 is known only from Peru, Department Cajamarca, province San Pablo, between 1850 and 2400 m of elevation. It grows 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).
