In the monocotyledons, the term etagen/storied relates to the arrangement of cells of the lateral meristem (etagen meristem) and the cork tissue (storied cork) as visible in transverse plane (Cheadle, 1937; Rudall, 1991; Donoghue, 2005; Evert, 2006; Verma & Khosa, 2012), while in the dicotyledons, it refers to the stratified arrangement of cells of the vascular cambium (Fig.
At a basic level, three major developmental shifts must occur to establish a normal, functional gemma: 1) a shoot meristem must be formed in a position that would normally bear a leaf, 2) the extension of the shoot must be slowed and then arrested at an early stage of development and 3) an abscission layer must form to allow the gemma to be dispersed.

The shoot meristem, which will give rise to all the "above-ground" organs such as the stem, the leaves and the flowers, and is the site of photosynthesis; and the root meristem, which gives rise to the root system, which lies below the ground and provides water and nutrients to the plant.
