DE: Windengewächse

They can easily be recognized by their funnel-shaped radially symmetrical corolla; the floral formula for the family has 5 sepals, 5 fused petals, 5 epipetalous stamens (stamens fused to the petals), and a 2 part syncarpous and superior gynoecium. The stem of these plants is usually winding, hence its Latin name (convolvere = to wind). The leaves are simple and alternate, without stipules.
