Editing Monocotyledon (section)

====Roots and underground organs====
The lack of cambium in the primary [[root]] limits its ability to grow sufficiently to maintain the plant. This necessitates early development of roots derived from the shoot (adventitious roots). In addition to roots, monocots develop [[stolon|runners]] and [[rhizomes]], which are creeping shoots. Runners serve [[vegetative propagation]], have elongated [[internodes]], run on or just below the surface of the soil and in most case bear [[scale leaves]]. Rhizomes frequently have an additional storage function and rhizome producing plants are considered [[geophytes]] (Tillich, Figure 11). Other geophytes develop [[bulbs]], a short axial body bearing leaves whose bases store food. Additional outer non-storage leaves may form a protective function (Tillich, Figure 12). Other storage organs may be [[tubers]] or [[corms]], swollen axes. Tubers may form at the end of underground runners and persist. Corms are short lived vertical shoots with terminal [[inflorescences]] and shrivel once flowering has occurred. However, intermediate forms may occur such as in ''[[Crocosmia]]'' (Asparagales). Some monocots may also produce shoots that grow directly down into the soil, these are [[wikt:geophilous|geophilous]] shoots (Tillich, Figure 11) that help overcome the limited trunk stability of large woody monocots.<ref name=Kubitzmmonohist/><ref name=TakhtajanLiliops/>{{sfn|Chase|2004}}{{sfn|Tillich|1998}}
