Juncus hemiendytus var. hemiendytus

Hermann's dwarf rush

Family: Juncaceae · Type: annual · Native

Hermann's dwarf rush is a California native annual found in northwestern California, the Cascade Range, Sierra Nevada, San Bernardino Mountains, and Modoc Plateau in damp open areas, especially vernally wet sites, at elevations of 400 to 3,200 meters. Flowering details are limited in the provided data, but this delicate rush has extremely narrow stems less than a millimeter wide. Growing with slender, compact stems typically 10 to 30 centimeters tall, it forms small, dense clusters in seasonally wet environments. Its stems feature minimal branching with 1 to 2 small bracts, creating a subtle, understated appearance in its habitat. The plant's fruit notably extends beyond the perianth, a distinctive characteristic of this diminutive rush species.
