Viny or trailing shrub, branches up to 1 m long, internodes 20-80 cm, with moderately dense, stri- gose vesture of two-celled bayonet hairs throughout and scattered short gland-tipped hairs, stem woody or thick-herbaceous, older branches occasionally rooting at the nodes; leaves with 3-5 leaflets, 80- 100 mm long (holotype 149 mm), with petiole 18- 30 mm long (holotype 49 mm); leaflets lanceolate to lanceolate-elliptic, base obtuse to truncate, apex acute to acuminate, with moderately dense, strigose vesture of two-celled bayonet hairs, glandular hairs sparse on both surfaces; terminal leaflet somewhat larger than the first pair of lateral leaflets, 36-55 mm long (holotype 68 mm), 19-31 mm wide; first pair of lateral leaflets 30-40 mm long (holotype 49 mm), 9-20 mm wide, short petiolulate; pseudosti- pules lacking; inflorescence a pseudoterminal and/ or lateral raceme with 2 (rarely 3) axes and 15-61 flowers; pedicels 6-11 mm long, basally articulate, densely strigose vesture of two-celled bayonet hairs intermixed with short gland-tipped hairs; corolla white, rotate, moderately reflexed, lobes 5.5-9.5 mm long, sinuses 4-6 mm long, lobe/sinus ratio about 1.6, glabrous adaxially, sparsely strigose to hispid abaxially; calyx green, acute to acuminate, about 1/4-1/3 the length of the corolla lobes, strigose vesture moderate to heavy; anthers pale yellow, apices rounded, 2.2-3.8 mm long, glabrous abax- ially, a few scattered stiff hairs adaxially; filaments 1.5-2.7 mm long (holotype 0.7 mm), fused for less than 14 of their length, scattered stiff hairs along their margin; style 3.9-6.5 mm long, sparingly stri- gose over lower 34 of its length, hairs intermeshing with those of the anthers, stigma slightly capitate, exceeding staminal column by 1-2 mm; fruits glo- bose to elliptic-ovoid, mature fruits yellow-orange with darker orange-brown arms from pedicel to style scar, 20-30 mm long and 13-18 mm wide, surface smooth; seeds 60-200 per fruit, lenticular, flattened with narrow wing around margin of seed, 1.9-2.2 mm long by 1.4-2.0 mm wide, about 0.4-0.7 mm thick, brown, surface smooth to slightly rugose; pol- len tricolporate, 15-18 um diam., exine granular; mean pollen quantity 332,000 grains per flower; mean ovule quantity 146 per flower; mean pollen: ovule ratio 2315:1; n = 12.

Note

The only collection of this species to date, from near Chachapoyas, Peru, was in flower. Glasshouse-cultivated specimens flower year-round. We have also studied an isotype from Carlos Ochoa's personal herbarium. Correspondence with the herbaria cited as housing the isotypes failed to yield the specimens. Thus, the bulk of the study was focused on a large number of plants grown from seed of the type collection. Specimens cultivated (GJA #934) in glasshouses at the University of Connecticut as part of this study have been deposited in CONN, CORD, MO, WI, and US. This species is named in honor of Carlos Ochoa, who collected it and has made many important con- tributions to the systematics of Solanum through his fieldwork and writing. In correspondence, Ochoa gave the following ad- ditional collection information ". . . near Maino, some 15 km (air distance) southeast of Chachapoyas, 2600-2800 m alt. . . . Plants of more than 1 m in height with long-conic berries, 2-3 cm long and 1.5-1.8 cm in the maximum transversal diam., yel- low when ripe, edible according to local information. Vernacular name: Pepinillo."
