Herb, sometimes slightly woody, few- to many-branched, 2–7 dm tall. Stems sparsely to densely pubescent with straight one-celled or geniculate two-celled hairs, the straight hairs common on older growth, the geniculate hairs dense on new growth. Sympodia 2-foliate, usually geminate. Leaf blades 1–7 + 0.75 –3 cm, elliptic to elliptic-ovoid, chartaceous to membranaceous, sparsely to moderately pubescent adaxially and abaxially with 1- or 2-celled unbranched hairs, these lying flat along blade, denser along veins; base rounded to obtuse, often decurrent into petiole; apex acute; petioles 0.5–2.5 cm, moderately pubescent with unbranched hairs. Inflorescences with 1 –5 flowers, the axes sparsely to moderately pubescent with unbranched hairs; peduncle absent or nearly so; rachis absent; pedicels 5 –15 mm in flower, 12–20 mm in fruit. Flowers with the calyx 3–6 mm long, the tube 1–3 mm, the lobes 2–4+ 0.5–1.5 mm, linear-lanceolate, moderately to densely pubescent. Corolla 1–2.5 cm in diameter, rotate with abundant interpetalar tissue, chartaceous to membranaceous, white to purple, the tube 4 –10 mm, the lobes 2–4 + 1–2 mm, triangular, acute at apices, glabrous abaxially and adaxially. Stamens 3 –6 mm; upper, shorter filaments 1–2 mm, the lowermost, longer filament 3–7 mm, glabrous or pubescent; anthers 4–6+ 1–2 mm, oblong, the base cordate, the apex emarginate. Ovary glabrous; style 7–10+ 0.5 –1 mm, longer than the smaller stamens, closely appressed to larger stamen, curved near the apex; stigma to 1 mm wide. Berries 10–20 mm in diameter, globose, white to yellow when immature, maturing semitransparent, drying brown, glabrous, the mesocarp watery and held under pressure until dehiscing explosively at maturity. Seeds 10–35 per fruit, ca. 2.5+ 1.5 mm, the entire seed twisted, not flattened, with a small notch where connected to placenta, the surface with raised cell walls forming netlike projections. Figure 13. <i>Habitat and Distribution—</i> A weedy species of roadsides, grassy pastures, gallery forest, alluvial flats, forest edges, and open shrubby vegetation that occurs from central Bolivia to eastern Paraguay and the Brazilian state of Mato Grosso do Sul and south into northwestern Argentina between 300 –1,950 m in elevation (Fig. 5). <i>Phenology—</i> Flowering specimens have been collected in all months except August with a peak from October through February. Fruiting specimens have been collected in January through May and September through December. <i>Conservation Status—</i> The widespread distribution and abundant populations of <i>S. turneroides</i> give it an IUCN Red List Status of Least Concern. <i>Etymology—</i> The epithet <i>turneroides</i> presumably refers to a resemblance to the genus <i>Turnera</i> (Turneraceae), possibly due to the five-parted flowers that usually open in the morning and last for only a few hours. In the description, Chodat mistakenly likens the habit of <i>S. turneroides</i> to that of <i>S. caripense</i> Dunal, a viny member of <i>Solanum</i> sect. <i>Basarthrum</i>. <i>Additional Specimens Examined—</i> BRAZIL. <b>Mato Grossodo Sul:</b> Mun.

As noted by Nee (1989), the flowers of <i>S. turneroides</i> are not open in the heat of the day, as is also the case for <i>S. evolvuloides</i> (L. Giacomin, pers. obs.). When grown in the greenhouse at UT the flowers were open and very fragrant during the night and early morning. As the day gets warmer the flowers take on a wilted appearance. The pollinators of these flowers are unclear. Fragrance is unusual in the genus and is commonly only found in <i>S.</i> sect. <i>Pachyphylla</i> (Bohs 1994). The floral development is also of interest, with the stamens of equal length on the first day the flower is open and then the filament of the lowermost anther doubling in length the following day (Figs. 13C, D). Although herbarium sheets rarely display the feature, <i>S. turneroides</i> seems to spread rhizomatously. The hairs of <i>S. turneroides</i> are also unique in the section. While they superficially appear to be geniculate, like those of <i>S. olympicum</i> and <i>S. hoffmanseggii</i>, closer inspection shows that the hairs are simply bent downward on the stem and lack the 90 <b> °</b> elbow bend that characterizes the hairs of the latter two species. Using scanning electron microscopy, the base of these hairs appears to have a ring of small lateral cells, hinting that perhaps these hairs are reduced stellate hairs. If so, it may suggest that the simple hairs found in this and other species of sect. <i>Gonatotrichum</i> may represent evolutionary reductions from stellate hairs. The protologue of <i>S. turneroides</i> cites many Hassler specimens as syntypes, all from Paraguay, but gives no herbarium locations. <i>Hassler 4396</i> has been chosen from among the many syntypes cited because of the quality of the collection and its wide distribution in herbaria. The sheet from the Hassler herbarium at Gis chosen as the lectotype. Bitter cited four syntypes in his protologue for <i>S. gonatotrichum</i>, including <i>Fiebrig 2732</i> and three un-numbered specimens collected
