 narrow-leaved form with the point of the auricles projecting towards 

 the stem, but all gradations between this and the broad-leaved form 

 (/. latifoUa) with auricles obsolete or patent may be seen. The leaves 

 vary from being nearly glabrous to var. hirtus, Koch, Syn. Fl. Germ. 

 494 (1837), and the colour of the flowers from white to deep rose-pink. 

 The Bindweed delights in sunny roadsides and exposed margins of 

 cornfields.
