From Middle Dutch katteken (“catkin”, literally “little cat”). So named due to the resemblance of lengthier kinds to a kitten's tail, or, perhaps more probably, the fine fur found on some catkins (compare the pictures). Cognate with German Kätzchen, modern Dutch katje; compare French chaton (“kitten”; “catkin”). By surface analysis, cat + -kin.

A catkin or ament is a slim, cylindrical flower cluster, with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect pollinated (as in Salix). They contain many, usually unisexual flowers, arranged closely along a central stem which is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. For some time, they were believed to be a key synapomorphy among the proposed Hamamelididae, but it is now believed that this flower arrangement has arisen independently by convergent evolution on a number of occasions.
