Convolvulaceae

Twining, climbing or trailing non-woody (herbaceous) deciduous annual or perennial vines, some with milky sap. Plants with rhizomes and chlorophyll, green branching stems, and stalked, green, arrow-shaped leaves; or parasitic, lacking chlorophyll, with orange thread-like stems that are often abundant on plants they parasitize, primitive roots that disappear (are ephemeral) as plant develops, and tiny unstalked scale-like leaves. Leaves alternate, simple, sometimes lobed; stipules none.

Flowers white or pink, in axils, in cymes or solitary, sometimes with bracts. Each flower usually producing both pollen and seeds, and usually radially symmetrical. Petals 4 or 5, fused to form a bell-shaped, tubular or funnel-shaped flower. Sepals 4 or 5, separate or fused at base, persistent. Stamens 4 or 5, usually separate; bases attached to the inside of the petal tube. Carpels usually 2, fused to form 1 pistil; ovary located above point of attachment of other flower parts (superior) with 2 chambers; styles 1 or 2. Fruit a round to egg-shaped capsule, with 1-4 (-8) seeds.
