Sisyrinchium angustifolium Mill.
Common Name: STOUT BLUE-EYED-GRASS
Coefficient of Conservatism: 4
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Nt P-Forb

Moist shores, meadows, fields, thickets, and swales; oak-hickory forests, forest borders, grassy clearings. Plants with simple stems and sessile spathes belong here if the stems are very broadly winged (> ca. 3 mm).

Rare plants that do not seem to darken on drying may be distinguished from Sisyrinchium strictum by their wider stems (> 2.5 or more usually 3 mm), strongly unequal spathe bracts, and no tendency for peduncles and spathes to be geniculate at base.
