GENUS INDEX

GENUS CODE: SCIRP
GENUS SCIENTIFIC: Scirpus
GENUS AUTHORITY: L.
GENUS COMMON: Bulrush
GENUS SUMMARY: A genus of about 20 species, herbs, of circumboreal distribution, also with species in Australia, Malaysia, and South America. The complex of species including S. atrovirens, S. georgianus, S. hattorianus, S. flaccidifolius are difficult to identify, and some have doubted their validity. Although further work on this group is needed, they do generally appear to behave as biological species despite their morphological similarity. Schuyler (1967) writes that the remaining species in the key differ in minute characteristics and often the most satisfactory means of identification is by carefully comparing specimens of them. Despite the close morphological similarity of these species, their characteristics are reasonably constant even in areas where they coexist and occasionally hybridize.

SCIENTIFIC NAME: Scirpus flaccidifolius
COMMON NAME: Reclining Bulrush
SYNONYMY: [= FNA, K, Va, Z; < S. atrovirens var. atrovirens - C; = S. atrovirens Willdenow var. flaccidifolius Fernald - F]
PHENOLOGY: Late May-early Jul.
HABITAT: Bottomlands.
COMMENTS: Endemic to se. VA and ne. NC. 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 value.
