Solanum pocote Hieron. ex Millán, Revista Argent. Agron. 12: 117. 1947, nom. illeg. superfl., non S. pocote Hieron. (1881) .—

TYPE: Based on S. hieronymi Kuntze.

Erect to decumbent perennial herb up to 0.4 m tall; stems unbranched or branched near the base; roots usually in the form of a taproot, producing buds and ellipsoid tuber-like swellings ca. 1–2 × 0.5 cm. Stems moderately to densely pubescent with sessile to short-stalked stellate hairs 1.4–2 mm in diameter, with 4–5 lateral rays, the central ray 1–3-celled and up to 3 mm long, also moderately to densely pubescent with short unbranched glandular hairs up to 0.3 mm long, moderately armed with straight tapered prickles up to 7 mm long, these often minutely glandular-puberulent. Sympodial units 2- to 3-foliate, sometimes plurifoliate, the leaves not geminate. Leaves simple, the blades 2.5–12(21.5) × 2–7(16) cm, ovate to elliptic in outline, moderately to densely stellatepubescent abaxially, sparsely to densely pubescent adaxially with sessile stellate hairs up to 2 mm in diameter, with 4 lateral rays, the central ray 1-celled and up to 1.4 mm long, sparsely to moderately armed with prickles up to 7.5 mm long on the major veins abaxially and adaxially; base cordate or less often truncate; margin irregularly lobed; apex obtuse; petioles 2–6 cm long, moderately to densely stellate- and glandular-pubescent with stellate hairs like those of the stem, sparsely armed with prickles up to 3.5 mm long, these rarely with 4–8 rays at the apex. Inflorescences 2–10 cm long, extra-axillary, unbranched, with 5–10 flowers, weakly andromonoecious, the axes moderately to densely stellate- and glandular-pubescent, sparsely armed with prickles up to 5 mm long; peduncle 2–8 cm long; pedicels 1–5.5 cm long in flower and fruit, strongly deflexed downward in fruit, spaced 0.5–2.5 cm apart, articulated at the base, moderately stellate- and glandular-pubescent. Calyx 5–10 mm long, the tube 1–5 mm long, the lobes 3.5–7 × 2–2.5 mm, narrowly triangular, the apex acute, moderately to densely stellate- and glandular-pubescent abaxially, rarely with stellate hairs with stout prickle-like stalks up to 3.5 mm long, glabrous adaxially, moderately to densely armed with prickles up to 4 mm long; fruiting calyx accrescent and covering the lower ⅓ to ½ of the fruit, 7–15 mm long, the tube 1–5 mm long, the lobes 5.5–12 × 5–6 mm, triangular to narrowly triangular, sparsely stellate-pubescent, moderately armed with prickles up to 4 mm long, these sometimes with 4–8 rays at the apex. Corollas 2–4 cm in diameter, 13–22 mm long, rotate to stellate-pentagonal, chartaceous, white, the tube 5–15 mm long, the lobes 2–8 × 4.5–6 mm, deltate, the apex apiculate, moderately stellate-pubescent abaxially, glabrous adaxially. Stamens with filaments 1.2–1.5 × 0.3–0.5 mm; anthers 4.2–10 × 0.6–2 mm, narrowly lanceolate, not connivent, yellow, the pores directed distally. Ovary 2.3–3.2 × 1.6–2.5 mm, subglobose to ovoid, glabrous; style 7.5–15 × 0.5–1 mm, cylindrical, straight, glabrous, exserted; stigma capitate. Fruits 1.5–2.2 × 1–2 cm, subglobose, the apex obtuse, green to whitish-green and somewhat darker green-striped at the proximal end when immature, yellow at maturity, glabrous. Seeds 1.8–2 × 2–2.2 mm, flattened-reniform, lenticular, yellow, the surface finely foveolate.

Distribution and Habitat — Solanum hieronymi is distributed in northern Argentina, south-central Bolivia, and northwestern Paraguay (Dept. Boquerón) ( Fig. 6 View FIG ). It grows in disturbed areas (e.g. roadsides, borders of cultivated fields, grazed woodlands) often in sandy or clay soils and in chaco vegetation from 400–1830 m in elevation.

Phenology — Flowering between November and April and fruiting between February and June.

Conservation Status — Solanum hieronymi is distributed across a large area in Bolivia, Paraguay, and northern Argentina. It grows in highly disturbed habitats, and it is doubtful that there will be any significant reduction in population size or locations. With an extent of occurrence of ca. 820,000 km 2 and area of occupancy of 1,248 km 2, Solanum hieronymi is assigned a preliminary conservation status of “least concern” ( LC).

Etymology — Solanum hieronymi is named after Georg Hans Emmo Wolfgang Hieronymus (1846–1921) who collected in Argentina, Bolivia, and Brazil.

Vernacular Names and Uses — From the Santa Cruz Department in Bolivia, two names recorded on herbarium sheets were papa de zorro (I. G. Vargas C. 414) and tutía-tutía (A. Fuentes & C. Pítare 2400). These common names almost certainly refer to the globose or ellipsoid swellings on the roots (the common name tutia was given to S. aridum , another species with swellings on the roots). Other common names in Argentina include papaquisla, pocota, pocote, and pocotillo ( Matesevach 2002). Barboza (2013) reports that the tuber-like root swellings are edible.

Chromosome Number — Chromosome counts of Solanum hieronymi have shown it to have a variety of ploidy levels: n = 12 (G. Bernardello 505; T. E. Di Fulvio 824), n = 18 (A. T. Hunziker et al. 24847), n = 24 (R. Subils et al. 3859; A. T. Hunziker 24846), and 2n = 24 (G. E. Barboza et al. 1261) ( Moscone 1992; Chiarini 2007).

Notes — In habit and most vegetative and reproductive characters, Solanum hieronymi is similar to S. comptum but can distinguished by its white corolla (vs. light blue in S. comptum ), larger (1.5–2.2 × 1–2 cm) depressed globose fruits with a weakly accrescent fruiting calyx (vs. smaller (0.8–1 × 0.7–1.3 cm) globose fruits completely covered by the accrescent fruiting calyx), and small stellate hairs with central rays of 1–4 cells that are longer than the lateral rays (vs. central rays consisting of 1–2 cells and shorter or equal to the lateral rays). In S. hieronymi , large stellate hairs with stout yellow prickle-like stalks are absent or sparsely distributed on the petioles and calyces. In S. comptum , the same stellae are sparsely to moderately distributed on the stem, petioles, leaf blades, inflorescence axes, and pedicels, and densely so on the calyces. Solanum hieronymi also has short (up to 0.3 mm long) unbranched glandular hairs that are moderately to densely distributed throughout the plant, whereas S. comptum completely lacks glandular hairs.

Among the several duplicates of P. G. Lorentz & G. Hieronymus 361, the B and NY sheets were both annotated “ Solanum Hieronymi OK ” in Kuntze’ s hand (the B specimen was destroyed, but its image is preserved in F neg. 2778). Both the B and NY sheets likely represent original material as Kuntze is known to have worked at B, and the NY sheet was acquired from his personal herbarium. The B specimen has both a mature flower and a fruit, whereas the remaining duplicates contain only immature flowers and fruits. We have chosen the sheet NY–NY00172025 as the lectotype because it is likely to be the only other existing duplicate representing original material examined by Kuntze. Chiarini (2007) and Barboza (2013) incorrectly list the NY specimen as the holotype.

Morton (1976) discusses the convoluted case of the name S. pocote Hieron. Hieronymus intended to apply the name to a species of spiny Solanum , but cited S. tuberiferum var. arenarium Dunal in synonomy without providing any further descriptive details of the plant. This latter name is a synonym of S. montanum L., a non-spiny Solanum , and thus S. pocote Hiern. is also a synonym of S. montanum L. Millán (1947) attempted to rehabilitate the name S. pocote , applying it to a species of spiny Solanum . He cites the earlier name

S. hieronymi Kuntze in synonomy, making S. pocote Hiern. ex Millán a synonym of this name.
