In this article, the genetic diversity and systematics of 14 Solanum accessions representing 11 species growing in the southwestern highlands of Saudi Arabia were evaluated using morphological variations and molecular polymorphism generated by 13 ISSR primers. Substantial variations were scored in 26 morphological characters and reflected in the cluster analysis of the examined accessions based on morphological variation. In the cluster trees illustrating the relatedness of the examined accessions based on morphological variation and ISSR polymorphism, the accessions of S. villosum and S. nigrum were differentiated as one cluster and S. dulcamara was associated with S. sisymbriifolium. In the meantime, S. coagulans was clustered with S. macracanthum. The analysis of ISSR data confirms that S. villosum is related to S. nigrum and supports the grouping S. incanum and S. glabratum based on the morphological traits. Principle Component Analysis (PCA) analysis of morphological and ISSR data as a combined set, differentiated the examined species into four groups in a scatter plot. The differentiation of the species/populations in the PCA scatter diagram agrees with their separation in the cluster trees. The four groups are 1. S. macracanthum, S. coagulans and S. schimperianum. 2. S. glabratum and S. incanum. 3. S. dulcamara, S. sisymbriifolium and S. torvum, 4. S. nigrum, S. villosum, and S. villosum ssp. puniceum.

[CBNPMP-Thèmes] TaxonomieMots-clés : Solanum Résumé : The Dulcamaroid clade of Solanum contains 45 species of mostly vining or weakly scandent species, including the common circumboreal weed Solanum dulcamara L. The group comprises members of the previously recognised infrageneric groupings sect. Andropedas Rusby, sect. Californisolanum A. Child, sect. Dulcamara (Moench) Dumort., sect. Holophylla (G.Don) Walp., sect. Jasminosolanum (Bitter) Seithe, sect.Lysiphellos (Bitter) Seithe, subsect. Nitidum A.Child and sect. Subdulcamara Dunal. These infrageneric groups are not monophyletic as traditionally recognised, and the complex history of the classification of the dulcamaroid solanums is reviewed. Many of the species in the clade are quite variable morphologically; plants are shrubs, herbaceous vines or woody canopy lianas, and habits can vary between these states in a single locality. Variation in leaf shape and pubescence density and type is also extreme and has lead to the description of many minor morphological variants as distinct species. The flowers of members of the group are generally very showy, and several species (e.g., Solanum crispum Ruiz & Pav., Solanum laxum Spreng., Solanum seaforthianum Andrews) are popular ornamental plants that have occasionally escaped from cultivation and become naturalised. The clade is here divided into five morphologically and geographically delimited species groups to facilitate further study. One new species from southern Ecuador, Solanum agnoston S.Knapp sp. nov., is described here. Full descriptions and synonymies (including designations of lectotypes or neotypes), preliminary conservation assessments, illustrations, distribution maps, and an extensive list of localities are provided for all species.
