Caesarweed is a pantropical weed, having pink flowers
hollyhocks. Many taxonomists now believe it evolved somewhere in Asia.
Caesarweed grows to 2 meters in height. 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 also found in the Himalayas,
till 1800 m altitudes.
