Juncus digitatus is an annual herb forming small, dense clumps of thin, almost hairlike stems which are red in color much of the time and measure up to 10 centimeters tall. The leaves have blades no more than about 2 centimeters long and are mostly limited to the base of the plant. The
inflorescence is a single flower or a cluster of up to 8 flowers at the tips of the stems. Each flower has six lance-shaped
tepals a few millimeters in length which are reddish to greenish darkening to purplish near the tips. The fruit is a red or brownish, fingerlike capsule 1 to 2 centimeters long. ;Conservation
Juncus digitatus is most closely related to
Juncus triformis, which grows alongside it in one of the populations but not the other. Suitable habitat has been reduced by the conversion of the land to
agriculture. The spring water that feeds its natural habitat has been diverted by pipeline from one population, and the other may be impacted by ornamental rock mining. ==References==
