Description.

Suffrutescent herb to small shrub, 0.5-1.5 m tall, arising from a woody rootstock. Stems slightly angled when young, sparsely to densely pubescent with simple uniseriate trichomes to 0.5 mm long, these strongly ascending and all appressed to stem, occasionally (collections from Famatina in La Rioja province, Argentina) more floccose, the trichome base enlarged and slightly bulbous; new growth glabrous or densely pubescent with simple white trichomes like those of the stems. Bark of older stems yellowish grey, glabrescent. Sympodial units difoliate to plurifoliate, if difoliate, not geminate. Leaves simple to variably pinnatifid, 2.5-10 cm long, 1-7 cm wide, more or less lanceolate to narrowly elliptic in outline, the upper surfaces glabrous or with scattered simple uniseriate trichomes at the base and along the veins, these all appressed and pointing distally, the lower surfaces glabrous to uniformly pubescent with appressed and ascending simple uniseriate trichomes <0.2 mm long; primary veins 10-20 pairs, drying yellowish grey; base attenuate, winged along the stem; margins entire to 3-5-lobed, the lobes 0.5-3.5 cm long, 0.2-0.7 cm wide, incised to the midrib or very shallowly, in the basal part of the leaf; apex acute to acuminate; petioles very short to apparently absent, sparsely pubescent with ascending appressed trichomes on all surfaces like those of the stems, not twining. Inflorescences terminal or lateral, occasionally leaf-opposed, 1-2.5 cm long, simple or at most furcate, with 4-10 flowers in a pseudoumbel, glabrous to pubescent with ascending appressed simple uniseriate trichomes like those of the stems and leaves; peduncle 1-2.2 cm long; pedicels 0.7-1.2 cm long, filiform, ca. 0.5 mm in diameter, nodding at anthesis, pubescent like the rest of the inflorescence, articulated at the base in a very small sleeve; pedicel scars tightly packed at the tip of the inflorescence on a small platform. Buds ellipsoid to fusiform and elongate, the corolla strongly exerted from the calyx tube before anthesis. Flowers all perfect, 5-merous. Calyx tube 1-1.5 mm long, conical, the lobes 2.5-3 mm long, long-triangular to lanceolate, glabrous to pubescent with appressed white simple trichomes like those of the stems and leaves. Corolla 1-1.6 cm in diameter, violet or white, often with a green or yellowish green eye, stellate, lobed nearly to the base, the lobes 6-8 mm long, 3-4 mm wide, strongly reflexed at anthesis, densely and uniformly pubescent abaxially with minute simple uniseriate trichomes <0.1 mm long, glabrous adaxially. Filament tube ca. 0.5 mm long, the free portion of the filaments 0.5-1 mm long, densely pubescent adaxially with tangled simple trichomes 0.5-1 mm long; anthers (3-)5-5.5 mm long, ca. 1 mm wide, ellipsoid, loosely connivent to occasionally somewhat spreading, poricidal at the tips, the pores lengthening to slits with age. Ovary glabrous; style 9-11 mm long, glabrous or pubescent with weak simple trichomes in the basal 2/3; stigma capitate, the surface minutely papillose. Fruit a globose berry, 0.5-0.7 cm in diameter, purple or reddish purple when ripe, the pericarp thin and somewhat shiny, glabrous; fruiting pedicels 1-1.5 cm long, ca. 1 mm in diameter, not particularly woody, secund and pendent from weight of fruit. Seeds ca. 20 per berry, ca. 1.5 mm long, ca. 1.5 mm wide, flattened reniform, yellowish brown, the surfaces minutely pitted, the testal cells rectangular; stone cells present. Chromosome number: n=12 ( Moscone 1992).

Discussion.

Solanum salicifolium is extremely (almost incredibly) variable in leaf shape (see Figure 2A ), ranging from simple and linear (the type of Solanum salicifolium ) to deeply pinnatifid with very narrow lobes (the type of Solanum tenuisectum ). This is the extreme of similar variation in leaf shape found throughout the clade, and has led to confusion over the identity and synonymy of this species. Morton (1976) suggested that leaves with a single pair of lobes sat the base might be a late season growth form. Like Solanum endoadenium and Solanum angustifidum , also of the eastern Andean slopes in Argentina, Solanum salicifolium is a shrubby species, but it never appears to become vining. Solanum salicifolium is distinguished from Solanum endoadenium by it eglandular, appressed, ascending pubescence of simple trichomes with slightly bulbous bases and its usually simple inflorescences with the flowers clustered near the tip. It differs from Solanum angustifidum in its leaves that are lanceolate, rather than elliptic, in outline, its simple inflorescences and its anthers borne on equal filaments.

Solanum salicifolium is also quite similar to three species of the Morelloid clade (sensu Weese and Bohs 2007) that are traditionally segregated as section Parasolanum and by some included in a wider section Dulcamara (Nee 1999), Solanum tripartitum Dunal, Solanum radicans L.f. and Solanum palitans C.V.Morton. Solanum tripartitum and Solanum palitans have both been included in molecular analyses and are resolved as members of the Morelloid clade (Weese and Bohs 2007). These taxa have pedicels that are flush with the inflorescence axis, rather than inserted into a small sleeve, and the flowers are spaced along the inflorescence axis rather than being clustered at the tip on a small platform. The berries of Solanum salicifolium contain stone cells, a characteristic of many members of the Morelloid clade, a few of the collections (e.g., Del Vitto & Moscone 852 from Mendoza, Argentina) I have examined have many, but more normally fruits have 1-3 of these hard, seed-like bodies. Possession of these hardened bodies in the fruits may indicate a relationship with Morelloid taxa, but the woody habit is more Dulcamaroid. As more taxa of both these groups are included in molecular phylogenetic studies of Solanum , their relationships may become more clear.

In describing Solanum salicifolium R.A. Philippi did not cite a particular herbarium specimen and potential syntype material annotated with the type locality has been widely found. I have selected the specimen in SI as the lectotype of Solanum salicifolium , a largely Argentinian species.

In selecting a lectotype for Solanum incisum , Morton (1976) stated that specimens from the locality of Hieronymus 220, Sierra de Achala, were a good match for the photo graph of the presumed holotype destroyed in Berlin (F neg. 2779), however, the types of Grisebach’s names are generally to be found at GOET, not B. A single sheet of Hieronymus 220 is present at GOET, making his designation unambiguous. In the Kuntze herbarium at now at NY there are two sheets annotated Solanum tenuisectum ; I have selected that with the locality of the protologue ("western Pampas", NY00172207) as the lectotype. Morton’s (1976) Solanum incisum var. septatopilosum was distinguished from the more typical variety by the possession of spreading trichomes, but plants collected from the same locality (e.g., Sleumer & Vervoorst 2399) have the typical appressed pubescence of Solanum salicifolium . The type of Solanum sericeum var. strigillosum (Hieronymus 812) represents the narrow-leaved extreme of Solanum salicifolium . Solanum sericeum Ruiz & Pav. is not a member of the Dulcamaroid clade, but its relationships are not clear.
