Kandym (lat. Calligonum) is a genus of perennial branching shrubs of the Buckwheat family. One of the striking features of juzguns is winged or covered with numerous setae fruits, which are easily carried by the wind, while avoiding sand burial. In places with a close occurrence of groundwater, some species take on the appearance of tree-like or large multi-stemmed shrubs, but on sands with deep groundwater, these same species may turn out to be low shrubs. Shrubs from 0.4 to 7 m tall, very branched, with an openwork crown.
