| The UV marks on
the petals of Field Bindweed do not coincide exactly with
the visual markings, being larger in the centre of the
flower. This is similar to the UV behaviour of its larger
relative, the Hedge Bindweed (Calystegia sepium). The flower of Field Bindweed reflects strongly in near IR. Also note the signs of UV fluorescence within the corolla. |
