notes Slo.: rumenoplodni razhudnik - , syn.: Solanum alatum Moech, Solanum luteum Mill. ssp. alatum (Moench) Dostál, Solanum miniatum Bernh., Solanum nigrum subsp. alatum (Moench.) Čelak, Solanum nigrum subsp. miniatum (Willd) Hartman. - Habitat: semi-ruderal, locally almost flat terrain; skeletal, calcareous ground; sunny, open, dry, nutrient poor place; average precipitations ~ 800-900 mm/year, average temperature 12-14 deg C, elevation 30 m (95 feet), Sub-Mediterranean phytogeographical region. - Substratum: soil. - Comments (pertain to pictures in Flicker album Solanum villosum ssp. alatum): Solanum villosum ssp. alatum is a common species native in most European countries, Turkey, Tunisia and Egypt (Ref.5). It is also introduced to some northern and eastern European countries as well as to other continents. Plants in the very large genus Solanum (around 1.500 species described) are generally considered poisonous. However, there are exceptions and it includes several food crops of the highest economic importance: the potato, the tomato and the eggplant, for example. Solanum villosum seems also an exception. Its leaves and berries are edible. However, some (for example Ref. 4.) consider it poisonous. It is an old Ayurvedic herb with multiple medicinal properties (Ref.1). A promising hope is also its mosquito larvicidal activity (Ref.2). Extract from its berries could be used in stagnant water bodies for the control of mosquitoes acting as vector for many diseases including dengue fever, a debilitating viral disease of the tropics, transmitted by mosquitoes. Chemical agents used today are losing their effectiveness. The taxonomy of the plant in literature is not settled yet completely. According to Nikolić (2020) (Ref.: 4) Solanum villosum ssp. alatum has yellow, orange or red berries. The whole plant is glabrous or hairy. Hairs, if present, are short, non-glandular, adpressed and pointing upwards. The stems and branches (only some of them in the plants shown) have longitudinal harsh ridges (see Fig. 6.). There are a few (3-5) flowers in the inflorescence. Other similar species have more of them growing together.
