echioides (= Picris echiodes; Bristly Ox-Tongue) is a
common weed species. It is a largish, erect plant that feels quite
rough because of the bristle-like hairs on the leaves, stems and
phyllaries. The phyllaries are distinctive - with the outer row of broad
phyllaries and the upright inner row of narrow ones.
