Sympodial units 2- to 3-foliate when more than one inflorescence per shoot, but often only one formed and then appearing plurifoliate, the leaves not geminate. Leaves simple, the blades 2–10 × 1–5 cm, ovateelliptic, elliptic, or oblong in outline, discolorous, densely stellate-pubescent abaxially, less densely so adaxially with hairs like those of the stems, unarmed or sparsely armed with prickles up to 3.3(5) mm long on the major veins abaxially and adaxially; base cuneate to subtruncate; margin subentire, sinuate or shallowly lobed with 2–6 lobes per side; apex obtuse to acute; petioles 0.5–5 cm long, densely stellate-pubescent, unarmed or sparsely armed with prickles up to 4 mm long. Inflorescences 1–2.5 cm long, extra-axillary, unbranched or forked, with 1–6 flowers, weakly andromonoecious with the proximal flowers hermaphroditic and the distal flowers staminate, the axes moderately to densely stellate-pubescent, unarmed or very sparsely armed with prickles up to 3 mm long; peduncle up to 2 cm long or absent, with the lowermost flower(s) emerging directly from the node; pedicels 1–2(3) cm long in flower, 2–4 cm long and curved downward in fruit, spaced 0.5–1.5 cm apart, articulated at the base, moderately to densely stellate-pubescent, unarmed or very sparsely armed with prickles up to 1.5 mm long.

Corollas 1.7–3.5 cm in diameter, 12–16 mm long, stellate to stellate-pentagonal or rotate-stellate, chartaceous, usually white, sometimes pale blue-violet, the tube 2–6 mm long, the lobes 5–9 × 4–8 mm, deltate to triangular, the apex acute, densely stellate-pubescent abaxially, glabrous adaxially. Stamens with filaments 0.6–1.8 × ca. 0.2 mm; anthers 7–8.5 × 1.2–2 mm, narrowly lanceolate, somewhat connivent, yellow, the pores directed distally.

Seeds 1.5–2.3 × 1.1–2 mm, flattened-reniform, lenticular, yellow, the surface finely foveolate.

Distribution and Habitat — Solanum aridum occurs in northern and central Argentina, eastern Bolivia, and western Paraguay ( Fig. 4 View FIG ). It typically grows in disturbed areas such as roadsides and waste areas, often in sandy or clay soils. Most specimens examined occur at elevations between 300–1,200 m, but one sheet (C. Peláez 308) reported an elevation of 2,025 m.

Phenology — The species flowers between September and May, and fruits between November and July.

Conservation Status — Solanum aridum is distributed over a large area in Argentina, Bolivia, and Paraguay with a calculated extent of occurrence of ca. 1 × 10 6 km 2 and an area of occupancy of 1,376 km 2. It is common throughout its range and typically grows in disturbed areas, and there is no evidence that the size of its populations or number of locations are declining. Solanum aridum is therefore assigned a preliminary conservation status of “least concern” ( LC).

Etymology — The epithet aridum means dry or withered and was applied by Thomas Morong ( Morong and Britton 1893) because of the perceived “parched, dried appearance” of the plant.

Vernacular Names and Uses — Matesevach (2002) and Barboza (2013) report several common names from Argentina: comida de víbora, meloncillo, melon del campo, and pocotillo. Two specimens from Bolivia, G. Bourdy 2082 and R. de Michel et al. 2539, collected in Cordillera Province in Santa Cruz Department, recorded the names tutia and tutiami, respectively. Label information from G. Bourdy 2082 states that the fruit was ground and used to treat scabies. The name tutia very likely refers to the ellipsoid tuber-like swellings on the roots, a name similar to tutía-tutía, which was applied to S. hieronymi , another species with root swellings.

Chromosome Number — Several meiotic and mitotic chromosome counts of vouchered specimens have shown Solanum aridum to be a diploid, with n = 12 (R. Subils et al. 3566; G. Bernardello et al. 487, as S. juvenale ; Di Fulvio 803, as S. juvenale ) and 2 n = 24 (G. E. Barboza et al. 276; G. E. Barboza et al. 782; F. Chiarini 16) ( Moscone 1992; Chiarini and Bernardello 2006; Chiarini 2007).

Notes — In habit and reproductive characters, Solanum aridum resembles S. juvenale , and some intermediate forms can be found where the two species’ ranges overlap ( Morton 1976; Chiarini 2007). However, S. aridum can be separated from S. juvenale by the absence or very sparse density of prickles on the stem, petioles, leaf blades, inflorescence axes, pedicels, and calyces, whereas S. juvenale is typically moderately to densely armed with prickles, particularly on the calyces. The prickles on the leaf blades are usually much shorter in S. aridum (up to 3 mm long), while in S. juvenale they are up to 8 mm long. Solanum aridum also has larger leaf blades (2–10 × 1–5 cm) that are usually sinuate to shallowly lobed, compared to smaller leaf blades in S. juvenale (1.8–5.5 × 1–2.5 cm) that are more deeply lobed.

The ploidy level consistently differs between the two species, with Solanum aridum being 2 n = 24 and S. juvenale being 2 n = 48. Experimental studies in the greenhouse by Chiarini (2007) showed that crosses between S. aridum and S. juvenale produced triploid plants (2 n = 36) and that ca. 90% of reciprocal crosses between the two species resulted in offspring that produced fruit with an expected amount of seeds, yet only ca. 7% of seeds were viable. Solanum aridum was also shown to be self-incompatible.

Of the 11 sheets of T. Morong 1007 we examined, five are mixed collections of Solanum aridum and S. multispinum (the WIS ex WELC sheet has a specimen of Turnera sp.) and one sheet is composed only of S. multispinum . Nee et al. (2006) outlined the mixed elements of the T. Morong 1007 collection, but here we explicitly identify the elements of each sheet. The sheets at K, MO, NDG, and PH consist solely of S. aridum . The BM sheet contains seven elements; six are Solanum aridum , but the densely prickly plant outlined in pencil with the round fruit is S. multispinum . The sheet at E contains three elements. The left-hand one is S. multispinum and the two right-hand ones are S. aridum ; these have been annotated by M. Nee as “a.” and “b.” for S. multispinum and S. aridum , respectively. The GH sheet consists of five elements; the four densely prickly specimens, each with a round fruit, are S. multispinum , and the central element with few prickles and buds only is S. aridum . The sheet at NY has five elements; the four flowering ones are S. aridum , and the densely prickly one with the round fruit is S. multispinum . The WIS ex WELC sheet contains six elements; five are S. aridum (four with fruit), and the other was determined by M. Nee as Turnera sp. and is indicated in pen on the sheet.

Finally, of the two sheets of T. Morong 1007 at US, one sheet ( US – US 01014263 [ US –1324449]) is composed only of S. multispinum while the other ( US – US 00027459 [ US –48029]) contains only S. aridum . When selecting one of the two US sheets as the lectotype, Morton (1976) was unambiguous: “One of these plants [ US –1324449] is the very spiny plant with stipitate-glandular stems, peduncles, and pedicels, and leaf-blades cordate at [the] base that was described a little later as S. multispinum N. E. Brown ; the other [ US –48029] is a nearly spineless plant (the few spines present being small and inconspicuous), lacking stipitate-glands, and with cuneatebased leaf-blades. I choose the latter as lectotype ...” The sheet is also annotated as “ lectotypus ” in Morton’ s handwriting. Nee (in Nee et al. 2006) incorrectly states that the lectotype sheet is a mixture of S. aridum and S. multispinum when in fact it is composed exclusively of S. aridum .

In the protologue of Solanum elaeagnifolium var. ovalifolium, Kuntze (1898) cited his collection (C. E. O. Kuntze s. n.) from Salta Province, Argentina. Two specimens of this collection were located at NY and US. Kuntze did not indicate the location of a holotype, so we have chosen the specimen C. E. O. Kuntze s. n. (NY–NY00139143) as the lectotype. Both NY and US specimens are from Kuntze’ s herbarium and are annotated in his handwriting, but we chose the NY specimen as lectotype because it is the more complete of the two and contains several additional flowering and fruiting elements. Similarly, the collection T. Rojas 346 from Presidente Hayes Department, Paraguay was cited in the protologue of S. aridum var. pusillum , but the herbarium where the collection was deposited was not indicated. Although the specimen now conserved at G constitutes original material, we cannot be completely certain that it was the only one used for the description, and thus we have designated the specimen T. Rojas 346 (G–G00306542) as lectotype.
