“Sonchus Asper Flower Stem Section,” by Gerd A. Günther
Günther says: “This photomicrograph is of a flower stem of Sonchus asper (spiny sowthistle), a common thistle with wonderful yellow blooms. All over the plant stem, in a high density on the flower stems, these plants have tiny little hairs with red, small tips. Two of them are shown here with a cross section of a flower stem.”
