Polycormon
In botany, a plant population that has emerged from a single plant through vegetative propagation is called a polycormon or polykorm , or more rarely a dividuum : several upright shoots sprout from subterranean shoot sections such as rhizomes . When a polycormon becomes independent, it can disintegrate into several independent individuals, for example by dying off old parts of the rhizome. Examples of this are a single berry ( Paris quadrifolia ), reed ( Phragmites australis ), bush anemone ( Anemone nemorosa ) or bracken ( Pteridium aquilinum ). The individuals of a polycormon are genetically identical (clones), since they arise from a single plant, and therefore form a gene .
A type of branching in wood plants is called polycormic: side axes straighten up and take the form of a main axis. This meaning of the term is older and was introduced by Vöchting in 1884 .
