Taxonomy Comments: Two taxa have often been recognized, have different distributions, and may warrant recognition. Var. floridanum has plants green, leaf sheaths (especially the lower) moderately to densely hairy, and leaf blades hairy on the upper surface from base to apex. Var. glabratum is distinctly blue-green when fresh, has leaf sheaths glabrous (or the lowest very sparsely hairy), and leaf blades glabrous or hairy on the upper surface only at the very base.
