Juncus minutulus
Juncus minutulus is a species of rush (Juncaceae) informally[1] referred to as minute rush, dwarf toad rush and annual rush. DescriptionAn annual, resembling and easily confused with a tiny Juncus bufonius with all parts smaller and with flowers rarely opening (cleistogamous): fruit capsule 2.5-3.0mm, stamens usually (2)3 instead of 6, anthers 1/4-1/3 x filaments (not 1/3-1 x), tepals usually shorter than 4mm, inner tepals acute (not long-tapering), 0-1(2) stem leaves, 1–3cm long.[2] J. bufonius also has cleistogamous forms that can very much resemble this in these features therefore all features should be examined carefully (such as inner tepal tip shape).[3][4] RangeEurope & North Asia, possibly cosmopolitan but reliable records are limited.[2][5] HabitatSimilar to Juncus bufonius with which it may grow. Turkey: Wet or temporarily wet, usually open soil, 0–1800 m.[6] Spain: Wet pastures or those in temporarily flooded places, on somewhat saline soils; 0-2900m ("Pastos húmedos o de lugares temporalmente inundados, en suelos algo salinos; 0-2900 m").[4] Istria: Wet roads, fields, ruderal regions.[7] Siberia: In wet lowlands, along banks of water reservoirs.[8] Further reading
