Beschreibung:

Urena lobata, Caesarweed (Bur mallow, Pink burr) is an annual, variable, erect, ascendant under shrub and measuring up to 0.5 to 2.5 meters tall. The stems are covered with minute star-like hairs and often tinged purple. It is a pantropical weed, having pink flowers like miniature hollyhocks. The lobed leaves are covered in star-shaped plant hairs which give the leaves a grayish color and raspy feel. The derivation of the common name is uncertain, but may have come from the Latin caesius "bluish-gray" or caesariatus "covered in hair". The ovary of the flower is five-carpellate. If pollinated, each carpel or chamber will produce a seed. The fruit, about a centimeter in diameter, is a flattened globe and dries when mature. It snaps easily from the plant and each of the five wedge-shaped mericarps separate. The outer surface of each mericarp is covered with glochids, minute hooked spines that cling to fabrics and fur and tangle in hair. It is widely distributed as a weed in the tropics of both hemispheres including Southeast Asia. Originally published at Urena lobata
