Chamaechorie

The legumes of the bladder bush, which are blown up by carbon dioxide, are also spread chamaechor by the wind

Feld-Mannstreu , a typical “steppe roller”, in which the above-ground part of the plant in its entirety is driven away by the wind by rolling.

The Chamaechorie also anemogeochory is a propagation strategy that is used by plants. It represents a sub-form of anemochory , the spread by the wind. The plant is called ground runners , trolleys , Tumbleweed , Steppe scooter or steppe witch , in North America and Australia and Tumbleweed .

Chamaechore spread is always present when fruits, whole plants or parts of them are detached and driven rolling or sliding along the surface of the ground by the wind. This spreading form is typical for steppe plants and is particularly common in butterfly flowering plants . Typical trolleys also found in Central Europe are the fruits of the gigantic tragacanth and the blistered fruits of the bladder bush . The best-known chamaechor spreading plants include the real rose of Jericho ( Anastatica hierochuntica ) and the Ruthenian salt herb ( Kali tragus ) as well as in the Central European and Pannonian flora the field man's litter ( Eryngium campestre ), the crescent umbel ( Falcaria vulgaris ), the broom Radmelde ( Bassia scoparia ), the perennial rapeseed yolk ( Rapistrum perenne ), the white amaranth ( Amaranthus albus ) and - very rarely - the Tátorján sea kale ( Crambe tataria ).
