Sagittaria calycina Engelmann. clade: Calycina Group. Hooded Arrowhead. Phen: May-Sep. Hab: Seasonally exposed shores and flats of ponds, pools, and impoundments. Dist: N. OH and MI west to SD and CO, south to sw. VA, c. TN, LA, TX, and Mexico; disjunct in CA. Scattered occurrences eastwards are difficult to interpret as to 'nativeness', being primarily or entirely in manmade wetlands, to which they may have arrived by a diversity of means. First reported for SC by Hill & Horn (1997).
