Juncus triglumis var. albescens
Limy shorelines and marshes in the high peaks of the Wallowa Mountains. 2300–2400m. BW. ID; across North America; eastern Russia. Native.
Juncus triglumis is a well-marked species with a small terminal flower cluster, pale flowers, and tailed seeds. Some study is needed to clarify the subspecies in North America. The septate leaf character is difficult to detect in some specimens. The leaves are minutely hollow, usually with two longitudinal tubes.
