Scirpus flaccidifolius (Fernald) Schuyler. Common name: Reclining Bulrush. Phenology: Late May-early Jul. Habitat: Bottomlands. Distribution: Endemic to se. VA and ne. NC.
ID notes: Ludwig (1993) found the following characters to be most useful in distinguishing S. flaccidifolius from S. georgianus growing in the same region: bristles 1.2-1.4 mm long (vs. absent or mostly < 0.2, rarely to 1.0 mm long in S. georgianus), spikelets 1.5-2.1 mm wide (vs. 1.1-2.2 mm wide), spikelets 3-9 (-12) per glomerule (vs. 4-23), and inflorescence rays 5.5-17.9 cm long (vs. 3.5-13.5 cm long). Bristle length was the only character which consistently separated the 2 species; other characters showed overlapping values of possibly statistical significance.
Origin/Endemic status: Endemic
