Type: Type: Described from southern Europe.
Distribution: Distribution: Most of Europe and Asia, N.Africa; introduced elsewhere.
Comment/Acknowledgements: A common species of wet places in the hilly parts of Pakistan. It is easily distinguished from the previous species by its leaves not spine-tipped and each individual flower subtended at the base by a pair of short bracteoles.

Some forms of this species have been mistaken for Juncus effusus L. (R.R.Stewart, l.c. 40), a species of N.Temperate zone, India (?) (Sikkim to Khasia) eastwards to Malaysia, Australia and New Zealand. It is distinguished by its obovoid capsules, emarginate at tip, about as long as the perianth, flowers smaller and often only with 3 stamens.
