Protologue Description: Jaltomata andersonii Mione. TYPE: Peru. Dept. Lima: prov. Huarochirí, highway from Lima to La Oroya between km 82 & 83, 2500 m, with J. propinqua (Miers) Mione & M. Nee, 16 Jan 1998, T. Mione, S. Leiva G. & L. Yacher 622 (Holotype: NY!; Isotype: CONN!).

Herba perennis usque ad 20 cm alta, petiolo usque ad 1 cm longo, foliis et axibus pilos digitiformes, glanduliferos apice ferentibus, flore solitario, corolla purpurea, late crateriformi-rotata usque ad 3.7 cm cruciatim, filamentis maxime villosis basi.

Much branching, presumably perennial, herb to 20 cm, the hairs of the younger axes and leaves gland-tipped. Leaves alternate, sometimes geminate, the blades ovate, 4-7.5 cm long (to 10.5 cm on Spooner et al. 7364a ) X 2-3.5 cm wide, 3-4 pairs of primary veins, the apex often somewhat acuminate, the base usually cuneate and symmetrical or nearly so, adaxially densely pilose due to erect finger hairs, abaxially sparsely pubescent (nearly glabrous on Laudeman 5365 ), the margin nearly entire to sinuate-dentate, ciliate, the petiole to 1 cm long. Peduncle unarticulated, villous, 13-18 mm long; flower solitary. Calyx green, rotate, 16-21 mm across at anthesis, the lobes triangular with an acute apex, abaxially with a raised costa, bearing gland-tipped finger hairs to 3 mm long, and stalked multicellular glands (illustrated in Mione and Serazo 1999) 85-100 µm long, adaxially with a uniform covering of erect, glandless hairs 0.24 - 0.3 mm long, the margin with two classes of hairs: gland-tipped finger hairs to 2.8 mm long and glandless hairs to 0.1 mm long; calyx to 25 mm across with fruit. Corolla broadly crateriform-rotate, 5-lobed (Figure 3A), to 3.7 cm in diameter, purple with 5 pairs of dark-green maculae in a proximal ring, each pair of maculae straddling the main vein that extends radially to the tip of a corolla lobe, closing for the night, the margin ciliate, with glandless finger hairs to 0.6 mm long; both faces of corolla with abundant, evenly distributed stalked multicellular glands 85 - 100 µm long. Stamens 5, 6.9-7.2 mm long, filaments straight, extremely villous at base (Figure 3A, B); anthers (Figure 3C, D) 1.9-2.8 mm on pressed specimens, to 3.9 mm long on specimens preserved in alcohol in Peru, drying brown, or yellow if covered with pollen. Style straight (Figure 3B), 5.7-6.3 mm long, 0.15-0.36 mm wide at midlength. The stigma the same width as the distal end of the style, 0.21-0.3 mm wide (pressed), 0.36 mm wide (preserved in alcohol in Peru), both measured perpendicular to the length. Ovarian disk broad, girdling base of the ovary (Figure 3B). Gynoecium glabrous, except for stigma papillae to 13 µm long; ovary glabrous but appearing villous (Figure 3B) because of the dense vestiture of the stamen bases. Berries of unknown color, probably orange or red, 12 mm across (measured on Laudeman 5365 ).
