Description.

Erect or prostrate (in mountainous areas) annual up to 70 cm, stems reddish, glabrous or scarcely papillate. Lower leaves up to 80.0 × 0.5-1.0 mm, much shorter in the middle and upper stem parts, linear or filiform, with a mucro 0.6-2.0 mm long. Flowers in axillary clusters and arranged in the main inflorescence. Flower clusters (located below the main inflorescence) abundant, consisting of two flowers surrounded by bracts and bracteoles that are connate almost to the top and not gibbous basally; perianth segments of each flower membranous, glabrous, r-shaped, their tips appressed to each other, hardened and not forming a tight conus, with white, small tubercles 0.3-0.5 mm long or without any projections in the flexure; styles with stigmas ca. 1.0 mm; fruits 1.0-1.3 mm, depressed roundish. Flowers in the main inflorescence with (almost) free, basally not gibbous bract and bracteoles (that are appressed to the stem), hermaphrodite; perianth segments membranous, glabrous, r-shaped at fruiting stage, (1.5)2.0-2.5 mm long, membranous above the flexure and not forming a distinct conus; two abaxial segments usually have short erose wings (up to 1.0(1.5) × 1.5 mm), their tips (above outgrowths) hyaline and not stout; anthers 0.6-0.9 mm long; styles with stigmas ca. 1.0 mm; fruits lenticular, 1.1-1.5 mm. Seed seems to be vertical (due to anacrostyly) but is indeed horizontal.

Habitat.

Cold stony deserts at elevations of 2800-4400 m.

Phenology.

Flowering: July-September; fruiting: September-October.

The specimens from India reported by Dhar and Kachroo (1983) and Klimeš and Dickoré (2005) were not examined by us. All investigated specimens belong to Salsola hartmannii and S. tragus . However, S. collina is present in North Pakistan and its occurrence in Jammu and Kashmir is predictable.

General distribution.

Temperate Eurasia and East Europe; alien in West/Central Europe, Scandinavia and North America.
