The currently accepted scientific name of three-flowered rush is Juncus

a Eurasian variety and J. triglumis var. albescens as a New World
variety.  The second is commonly referred to by its synonym, Juncus
albescens [6].  Other authorities argue that the two entities are in

Triglumis var. albescens is calcareous-soil limited [5].
