Class:angiosperms
Group:monocotyledons
Order:Poales
Family:Poaceae
Tribe:Eragrostideae
Genus:Aeluropus
Scientific name: Aeluropus micrantherus Tzvel.
Name acc. to:Gubanov 1996
Description:Plant 6-30 cm tall, gray-green, rigid, culms procumbent or ascending. Leaves flat or convolute, 1-3 mm wide; ligule very short, at margins with 2-4.5 mm long hairs. Inflorescence spikelike (racemes congested on inflorescence axis), up to 7 cm long, somewhat unilateral. Spikelets 3-6-flowered. Lemma 5-9-veined. Anthers 0.6-0.8 mm long.
Tax. Comments:Near to the widespread and highly variable species Aeluropus littoralis (Gouan) Parl., which occurs from Europe to temperate Asia.
Comments:Species adapted to saline soils in Central Asian desert regions. The tough, widely spreading rhizomes and stolons make them effective soil stabilizers.

perennial (i)living for several to many years, as opposed to annual and biennial
acc. to: FoC online
Parasite status: (i)Is the plant a half- or full parasite?no parasite/saprophyte (i)Plant fully autonomous, leaves with chlorophyll

Simple or divided leaves: (i)Are the leaves simple or completely divided in several parts? Blade of the leaf entire or (more or less) deeply dissected. Attention: There are various appearances of the leaf margin (from entire to toothed and lobed). Here, we ignore this and ask only for dissections that separate the leaf for more than one third of its length or width, whatever is smaller. Sometimes, it is difficult to tell apart compound leaves from a shoot system with simple leaves: look for stipulae and/or axillary buds at the ground of the leaves: if only some possess these structures, the others are most likely leaflets of a compound leaf.simple (i)Non-divided leaf, but margin may be incised nearly to the ground. inherited by order Poales: simple
Shape of blade: (i)Easy for simple leaves. In compound leaves use the general shape of leaflet. Always check the ground for largest leaves of a plant. To be worked out: how to handle pinnate leaves?linear incl.grasslike or oblong (i)Leaves more than two times longer than broad with more or less parallel margins; see character: stipule for ligula.
