Members of Convolvulaceae are usually climbing or trailing
plants, with alternate leaves along their stems. The flowers
have 5 sepals, a lightly 5-lobed funnel-shaped corolla, and 5 stamens attached to the corolla tube.
In the bud stage, the flowers are twisted, and unravel as
they open. There are 2 divisions in the pistil, each of which form a seed.
Members of this family have been cultivated for ornamentation,
and are popular in gardens and lawns. However, some introduced species are troublesome weeds in some areas. The Sweet Potato is a member of Convolvulaceae,
as is the Field Bindweed (Convolvulus arvensis).
A cosmopolitan family of 1500 species in 50 genera, mainly
herbs and shrubs with trailing or twining stems, sometimes
containing a milky sap. Usually instantly recognisable by
their trumpet shaped flowers.
