Visible and UV digital images reveal the homogeneous accumulation of UAPs in petals or their spatial distribution creating patterns. Visible (left) and UV (right) digital images indicate UV-absorbing areas in the corolla caused by the accumulation of UAPs. Scale bars = 10 mm. (A) Aquilegia formosa (Rannunculaceae, California) showing homogeneous UAPs accumulation in both petals (spur) and sepals (petal like) are UV absorbing. (B) Symphyotrichum spathulatum (Asteraceae, California) homogeneous UAPs accumulation in both disk and ray florets. (C) Ononis pubescens (Fabaceae, Spain) showing visible and UV veins, and keel and wings with high UV absorption. (D) Madia elegans (Asteraceae, California) showing a highly UV-absorbing bullseye in disk florets and base of ray florets. (E) Triteleia ixioides (Asparagaceae, California) showing UV-absorbing rays on the tepals and corona, in this case is accompanied by chlorophylls causing greenish purple rays in visible photography. (F) Malva sylvestris (Malvaceae, Spain) showing UAPs nectar guides in addition to anthocyanins in the remainder of the petal. (G) Parkinsonia florida (Fabaceae, California) showing visible dots and banner with high UV absorption. (H) Adelinia grandis (Boraginaceae, California) showing a UV-absorbing bullseye in the corolla.
