Juncus supiniformis Engelm.[FNA22, HC, HC2]
hair-leaved rush, spreading rush
Publication: Transactions of the Academy of Science of St. Louis 2: 461-462. 1868.
Origin: Native
Herbarium search: CPNWH
Notes: FNA22: "The northern California and southern Oregon populations (Juncus supiniformis in the strict sense) form long filiform leaves before flowering, are shorter, and have smaller flowers than the northern populations. Except for the filiform leaves, the variation in sizes appears to follow a rough latitudinal cline with the largest plants and largest flowers in Alaska.
Flowers of Juncus supiniformis often form bulbils."
