Solanum valdiviense Dun.

Chile Central

Lax shrub with arching branches, 1-3 m tall, suckering at the base. Stems glabrous to densely pubescent with uniseriate, simple or dendritic trichomes < 0.5 mm long, strongly ridged, the ridges pale; new growth sparsely to densely pubescent with simple or dendritic trichomes. Bark of older stems green to grey, the ridges paler. Sympodial units plurifoliate, the leaves often borne on short shoots. Leaves usually simple, highly variable in size and shape, on non-reproductive stems the leaves 3–6 cm long, 1–1.5 cm wide, lanceolate, occasionally with irregular lobes at the base, on reproductive stems the leaves more often elliptic, 0.9–1 cm long, 0.5–0.7 cm wide, membranous or somewhat fleshy, the upper surfaces glabrous to sparsely pubescent with simple or dendritic trichomes < 0.5 mm long, the lower surfaces glabrous to sparsely or densely pubescent with simple or dendritic trichomes like those of the upper surfaces; primary veins 2–7 pairs, not visible in elliptic leaves; base acute to truncate, in elliptic leaves more usually acute; margins entire, occasionally with one or two basal lobes in lanceolate leaves; apex acuminate to rounded in lanceolate leaves, acute to obtusely rounded in elliptic leaves; petioles 0.5–1 cm long in lanceolate leaves, 0.15–0.2 mm long in elliptic leaves, apparently not twining. Inflorescences terminal on short axillary shoots, 1–3 cm long, simple or occasionally once-branched, with 3–10 flowers clustered at tip, glabrous to densely pubescent with simple or dendritic uniseriate trichomes < 0.5 mm long; peduncle 1–3 cm long; pedicels 1–1.2 cm long, ca. 0.5 mm in diameter at the apex and base, filiform, nodding at anthesis, glabrous, sometimes tinged purple, articulated at the base in a short sleeve on a platform; pedicel scars short pegs clustered at the tips of inflorescence in a small group with the appearance of a platform. Buds ellipsoid, the corolla very exserted from the calyx tube before anthesis. Flowers all perfect, 5-merous. Calyx tube 1–1.2 mm long, conical, the lobes 0.5–1.5 mm long, deltate or quadrate, minutely apiculate, glabrous. Corolla 0.7–1.8 cm in diameter, white or purple, often white tinged with violet, stellate, lobed 3/4 of the way to the base, the lobes 3–5 mm long, 2–3.5 mm wide, strongly reflexed at anthesis, densely pubescent on the tips and distal lobe margins, otherwise glabrous. Filament tube minute, the free portion of the filaments 0.5–1 mm long, glabrous or minutely puberulent with simple trichomes; anthers 3–4 mm long, 1–1.5 mm wide, ellipsoid, loosely connivent, yellow, poricidal at the tips, the pores only partially lengthening to slits with age. Ovary glabrous; style 5–7 mm long, glabrous; stigma capitate, the surface minutely papillose. Fruit a globose berry, 0.5–0.7 cm in diameter, green or red when ripe, glabrous, the pericarp thin, shiny; fruiting pedicels 1.5–2 cm long, more or less woody, ca. 1 mm in diameter at the base, pendent. Seeds ca. 10 per berry, ca. 3 mm long, ca. 2 mm wide, flattened-reniform, reddish brown, the surface minutely pitted, the testal cells square. Chromosome number: not known.

(Figure 105). Solanum valdiviense is found in southern Chile and adjacent Argentina, from 100–2000 m. The altitudinal range of Solanum valdiviense is from almost sea level to the high Andes and it is apparently relatively common where it occurs.
