Convolvulaceae   (Morning-Glory Family)

Notes: Cusctaceae is a monophyletic clade within Convolvulaceae, and for this reason has been subsumed within the latter family.

There is no consensus among regional floristic resources on the treatment of Calystegia and Convolvulus as distinct genera. Morphological differences distinguishing the genera have included stigmatic lobe shape (linear and acute-tipped in Convolvulus; oblong and blunt-tipped, flat in Calystegia) and number of capsular locules (one in Calystegia, two in Convolvulus). Recent molecular studies indicate that Calystegia is nested within Convolvulus (Stefanovic, Krueger, and Olmstead, 2002). Recognition of Calystegia at the rank of genus makes Convolvulus paraphyletic, a situation that is avoided here.
