2. Stem smooth to striate; stems or leaf blade lower surfaces often glaucous; leaves membranous; phyllary midvein lacking a wing
2. Stem ribbed or angular; stems and leaf blade lower surfaces not glaucous; phyllary midvein winged
3. Basal leaf blades regularly crenate, crenate-dentate, to shallowly dentate, with 10-30 teeth per side, the distal ones with 3-10 teeth per side
3. Basal leaf blades entire, lobed, or dentate, with 0-9 teeth per side
