Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from convolvere, to wind). The leaves are simple and alternate, without stipules. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary).
